I. Background❑ Previously the government (old: Ministry of ICT, KCC) pursued

a policy to be able to switch early to the IPv6 system in casethe existing number of IPv4 addresses became exhausted, so atransition plan was established first in 2004, then modified in
2007, then modified again in 2010.
*32

Whereas the number of IPv4 addresses is about 4.3 billion (2 ), the number ofIPv6

addresses

is

2

128

(3.4×1,038)

which

is,

for

all

practical

purposes,

inexhaustible.
- This is because an IPv6 address is composed of 16 bits and 8 units, forexample: 2001:dc2:0:40:135:72df:9e74:d8a3.

ŸThe government has over the years made consistent efforts toimprove preparations for adopting IPv6 in both the private andpublic Internet, but support for each IPv6 network productneeded to implement the network (routers, switches, servers,etc.) and commercialization of IPv6-based services (Network
Enabled Service, etc) has been very poor nonetheless.

ŸThe preparation rate for the backbone network was 92%, 65% for
the subscriber network (as of Dec. 2013), and 60% for the public
network (as of Dec. 2010.)*

In fact, there was only one IPv6 service available which is the LGU+ LTE voiceservice that launched in August 2013 and gained 800,000 subscribers by theend of December 2013.

❑ In February, 2011, ICANN* declared its IPv4 address exhaustion

and final allocation policy, which states that each organization
can be assigned up to 1,024 IPv4 addresses at once.
*

ICANN (Internet Corporation for Assigned Names and Numbers) is a nonprofit- 1 -private organization established under the auspices of the US Department ofCommerce in 1998 to manage the domain name systems and allocate IP
addresses.
** Final allocation policy : Each organization can be assigned 1,024 IPv4 addresseach time.

Ÿ*Whereas the public and private sectors of other major countries
are quickly switching to IPv6, Koreans are not yet using it verymuch.
For example, IPv6 service use rate (as of Dec., 2013) was, in descendingorder, in Switzerland 12.5%, Romania 10.78%, Luxemburg 9.55%, Germany
7.22%, Japan 6.81%, USA 6.41%, and China 1.13%. But in Korea it was only
0.01%.

❑ As

domestic IPv4 addresses will be used up within two or
three years, we will be unable to expand existing services andhandle newly created demand (Cloud, Internet of Things (IoT),etc.) without switching to IPv6.

*

One reason is because when providing mobile Internet (LTE) services, each
subscriber requires two IP addresses (voice and data).

☞ To successfully respond to the impending huge growth indemand for Internet services and promote smooth executionof the Internet-based “creative economy”, we must now
establish a strategic roadmap to expand the infinite Internet
address system (IPv6) to encompass the entirety of the
network including all fixed and mobile entities.

- 2 -< IPv6 transition concepts >❑ IP address conceptsŸIP (Internet Protocol) is a mutual communication protocol for PC communication.
An IP address is absolutely required for connection and communication between
networks and/or mobile devices.

※ Each IPv4 address consists of eight bits and four units (ex. 211.192.38.1) so the total
number available is 232 (about 4.3 billion). Meanwhile, each IPv6 address consists of
16 bits and 8 units (ex. 2001:dc2:0:40:135:72df:9e74:d8a3) so the total number available
is 2128 (3.4×1038) which is practically infinite.

❑ IPv6 transition conceptŸThis means that existing IPv4-Only equipment (routers, switches, servers, etc.)
are replaced with IPv4/IPv6 compatible equipment or IPv6-Only equipment.

❑ IPv6 transition methods
Ÿ

Check if the existing equipment support IPv4-Only, IPv4/IPv6 or IPv6-Only andreplace the equipment or update the software.

※ Check whether the hardware chipset supports IPv6 and whether the software version
supports IPv6. Determine whether it is necessary to replace the equipment for IPv6transition.

Execution Status Overseas

1
❑ The

international organization ISOC (Internet Society) hosted`World IPv6 Launch Day’ on June 1st, 2012, officially signaling
the start of IPv6 commercial services with about 3,100
companies including Google participating.

※ Soon after many companies such as Google, Yahoo, Facebook and YouTube
began providing IPv6 commercial services. In Korea, KISA (Korean Internet
Security Agency), Daum and other companies also participated, but as of now
they are only providing test services.

Ÿ

The IPv6 Forum (launched as a non-profit organization
headquartered in Luxemburg in July, 1999) actually beganassigning the “IPv6 Ready” logo to all IPv6 supporting products
worldwide starting in September, 2003.

※ As of January 1, 2014, the total number of IPv6 Ready products in the world
was 1,587 with 94 being Korean.

ŸCurrently the IETF (Internet Engineering Task Force) is seeking
out issues related to network switching technologies andoperation for IPv6 introduction and making consistent efforts toestablish the international standards.

※ Mobile communication (LTE) provides voice and data service are using the464xLAT standard.

Ÿ

PC versions of Microsoft Windows higher than Vista 2007 cansupport IPv6 as well as all smartphones launched after 2010.
- 5 -※ Both Apple iOS 4.0 or higher (2010) and Android 2.3 or higher (2011) can
support IPv6.

❑ The

United States: Although the USA has the most IPv4
addresses in the world, in order to maintain their reputation as
the leader of the Internet in the IPv6 environment, the nation
has prepared a public sector IPv6 transition roadmap and is
now aggressively executing it.

ŸAuthorities will make sure that the government and publicorganizations switch to IPv6 preemptively as a role model sothat security issues can be alleviated and the private sector canbe encouraged to adopt IPv6.

ŸAll federal organizations adopted IPv6 for its backbone networkby September 2012, and all the federal government public service
websites and internal systems must migrate to IPv6 bySeptember 2014.

※ 546 (41.1%) out of 1,294 federal government websites already introduced IPv6
as of December 2013.

❑ Europe:

The EU formed an IPv6 task force to promote IPv6transition and is now encouraging its introduction in various
areas such as infrastructures, applications and services.

Ÿ

In 2011, the EU invested €6 million in its ‘Gen6 Project’ toimplement secure and efficient electronic government services
based on IPv6.

❑ Japan: In 2002, the government allowed for a special, one-year

corporate tax deduction whereby communication service
providers were able to deduct 12% of the purchase price ofrouters for IPv6 services. This was done as an incentive toentice companies and institutions to voluntarily switch to IPv6.
- 6 -

Ÿ

In 2008, the Ministry of Internal Affairs and Communication
established an ‘IPv6 Execution Plan’ that aimed to have thenation switch to IPv6 by the end of 2012. They recommended
ISP service providers to finish implementing the IPv6 system by
the end of 2011.

※ As of Mar. 2013, 54% of all the ISP service providers and 13% of CATV
service providers were providing commercial services based on IPv6.

❑ China: To quickly avoid impending problems arising due to alack of IPv4 addresses, China has been encouraging introductionof IPv6 at the national level.
Ÿ

By 2006, they had implemented thirty IPv6 regional networkbases throughout the nation and in 2013 they performed a slewof small scale tests on IPv6. China is now ready to pursue
commercialization in the 2014-2015 timeframe.

❑ India:

In March 2013, India revealed its IPv6 introduction
roadmap that applied to service providers, content providers,manufacturers and government organizations.

※ All government organizations will finish switching to IPv6 by Dec. 2017. Service
providers have already been offering IPv6 LTE services since July 2013. IPv6
services will be available for wired networks starting in July 2014.

- 7 -Viewpoints◈ Other countries are taking the following actions:

Announcing an IPv6 transition plan/roadmap
Ÿ Introducing IPv6 first in the public sector so encourage
widespread adoption
Ÿ Increasing the demand for related technologies and equipment
Korea also needs to seek out various political plans suitable forthe current situation such as preparing an IPv6 roadmap,
introducing IPv6 to government and public organizations, allowing
tax deductions and providing special support for small & medium
size companies.

for※ Since December of 2013, Daum has been testing additional websites based on
IPv6.

❑ (Equipment)

About 70% of domestic companies’ network
equipment such as routers support IPv6 but only 15% of theinformation security products support IPv6, which is very low.

※ 94 (70%) out of 134 network equipment products (routers, switches, etc.) madeby 28 small & medium companies in Korea are “IPv6 Ready” certified (inaccordance with the international IPv6 forum), and 30(15%) out of 197 CC*
certified products support IPv6.

Demand and Transition Forecasts① Demand forecasts❑ Higher demand for IP addresses as more handsets access theInternet.
Ÿ-The widespread promotion of wireless services such as
integrated wireless/wired services, smartphones and emergenceof 4G services has lead to a parabolic increase in the demand for
IP addresses.
More than 12 billion devices including servers, PCs and smartphones in theworld are connected to the Internet. By 2020, this figure will be increased to 50
billion units.
* Cisco Visualization(http://share.cisco.com/internet-of-things.html)❑ Domestic IPv4 address scarcity and demand forecastsŸ-

According to IPv4 address availability surveys, about 15 million(13.6%) of the total of 112 million IPv4 addresses are yet to be
used.
Considering the pattern of IPv4 address use in the past, we expect a shortage
within 3 to 4 years. Main service providers will face a shortage within 1 to 2
years.

ŸConsidering the changes in the number of IPv4 addresses
available during the years 2006 to 2010 before IPv4 address
scarcity was declared in 2011, and taking into account future
demand until 2017 based on the standard deviation method, we
can conclude that we will need about 330 million IP addresses in2017.

② Transition forecast❑ Since the declaration of IPv4 scarcity in 2011, the amount of

IPv6 traffic in the world has suddenly increased.
Ÿ-For the first 10 years after being launched in 1998 there was onlya slight annual increase in the amount of IPv6 traffic, but after
the scarcity of IPv4 addresses was announced in Feb 2011 theamount of IPv6 traffic has increased drastically.
Until 2011, the years prior to the announcing of IPv4 address scarcity, theamount of IPv6 traffic had increased to only 0.27% of all traffic, but as of Dec.
2013 it had suddenly increased to 2.75%.

Feb 2011, Declaration of
IPv4 address scarcity*Source : Google IPv6 statistics❑ The amount of IPv6 traffic will be suddenly rise from 2.75%(end of 2013) to 50% (by 2018).
ŸConsidering the trends of IPv6 traffic changes around the world,
Google conducted a study to forecast IPv6 traffic growth fromwhich they concluded it will jump from 10% at the end of 2015
to 50% by the middle of 2018.

- 16 -

*Source : Google IPv6 statistics

ŸCountries like the USA and Japan will introduce IPv6
aggressively in an attempt to lead the Internet market andimprove national competiveness, while countries like China andIndia will do so mostly to resolve the issue of IPv4 address
scarcity.

Ⅲ. Anticipated problems (Trouble Factors)❑ Delayed supply of commercial IPv6 services(Private sector) According to the existing IPv6 transition plan,
the rate of network preparation is increasing consistently, butthere are some delays in promoting IPv6 support related tovarious network equipment availability and service transition.

Ÿ-

Different

participants

such

as

networkandserviceprovidersanddevicemanufacturers are trying to avoid taking responsibility for introducing IPv6(“chicken-egg” problem).
-As there exists the burden of investment costs such as equipment replacement
and software updates, they are reluctant to introduce IPv6.

Local network (inside)

Internet (outside)
ServerNAT conversion table* Using Network Address Translation (NAT) that converts a private IP address to a
public IP address and vice versa, you can generate and use several thousand(theoretically 65,000) private IP addresses from a single public IP addressŸ(Public sector) For network equipment, IPv6 service has been
mandatorily required since 2008, but websites have not been
mandated to do so, so there has been a delay in the IPv6
service.
- 18 -

❑ Concerns over security vulnerability of IPv6 and the absence ofservice models
Ÿ

There have not been any significant efforts for developing
information security products by verifying quality through any
functional/performance evaluations and also there are some
vague concerns about security and threats in the IPv6
environment.

Ÿ

There have been an insufficient number of new services
developed to generate profits from the given IPv6 investments.

❑ There is a lack of specialists and absence of successful cases oftransition.
Ÿ

There is no sufficient system operation or manpower
development for the newly introduced IPv6 system and there
has not been any sufficient number of accumulated experienceand successful cases of IPv6 transitions, so industry participants
are reluctant to be the first to introduce IPv6.

※ About 70% of small & medium companies want to receive support in the formof expert training and technical consulting. (2013, KISA)< Problems Anticipated by a Delayed IPv6 Transition >❑ Limited

numberofresponses

tonewservicedemands

andnewcomers entry to the market

Ÿ

There is a restriction on starting new services requiring IP addresses andexpanding existing services.
*(Hosting company A) Complains about difficulties in attracting new customers
as so many IP addresses are required to conduct business.

*(Cable company K) As it was unable to acquire sufficient IP addresses, it
failed to execute its service expansion plans but was finally able to take over
IPv4 addresses from company D that went out of business.

- 19 -

❑ Use of additional equipment such as NAT leads to a cost increase
and degraded quality.

Ÿ

Due

to

the

conversion

betweenprivateIPaddresses

andpublicIPaddresses, there is difficulty in bi-directional one-to-one communication, so it
is hard to remotely control sensors and electronics.

Ÿ

Duplicate use of private IP addresses leads to an increase in complexity of
networkmanagement.

Public-privateIPaddress

conversion

degradesnetwork quality and increases NAT purchase costs.

❑ Foreign companies eating up the domestic market and difficulties in
exploring overseas markets

ŸIn the entire Internet industry including network/system integration (NI/SI) andprofessional consulting, there is a huge gap of technology power with foreigncompanies who are very willing to switch to IPv6, so there is significant
concern about losing domestic market share to foreign companies.

Ÿ

Due to the lack of IPv6 experience and technology, domestic companies arehaving a hard time exporting equipment or receiving orders on infrastructure
implementation projects.
*(IPv6 conversion equipment manufacturer A) They tried to participate in the
IPv6 implementation project funded by the Malaysian government, but theyfailed

in

❑ Issuesof

unfairness

betweencompanies

havingaddresses and those withoutŸService is not what they are competing for but it is more about how they get
IPv4 addresses, so the problem can degrade the overall fairness of theInternet service market.
*(Companies A and B competing for exclusive company sales) Company A
tried to make a contract on the condition that they get more IPv4 addresses
than company B. Company B suffered from the lack of IPv4 addresses.

Execution Strategy❑ Switchfrom ‘equipment improvement’ to ‘service oriented’

efforts.
Ÿ In the past, the existing IPv6 expansion policy focused on
equipment (network preparation rate improvements) but now ashift has been made to focus on practical IPv6 service use.
Ÿ

By launching commercial services for mobile communication, thewired Internet and websites at the same time, we can implement
a virtuous IPv6 cycle involving all aspects of the system(network, services, devices).

❑ Mandatory

introduction of IPv6 in the public sector forincreased use of IPv6
Ÿ When the government/public organizations implement a new
website or make changes in their existing website, they must use
IPv6, so that use of IPv6 can be extended to websites in theprivate sectors.

❑ Strengthening

the competitiveness of IPv6-based information
security products and promoting the security industryŸ

To alleviate groundless concerns over IPv6-based security
equipment and to promote the relevant security industry, we
will develop competitive products and establish more strict
evaluation criteria for IPv6 security vulnerabilities.

❑ New IPv6-based service model development
ŸDiscover new IPv6-based service models and executeprivate/government
collaboration
test
projects
andcommercialization to create new values and attract IPv6
investments.

IPv6 transition promotion and user environment creation① Tax deductions for companies introducing IPv6

◇ Tax deduction on IPv6 equipment❑ Tax deduction on IPv6 equipment (Mar. 2014-)※ Most companies have difficulties in creating profits when introducing IPv6
equipment, so they want incentives/assistance such as tax benefits from thegovernment.

Ÿ

A certain portion of the cost of purchasing IPv6 equipment(routers, switches) should be tax deductible (big companies 3%,
small & medium companies 7%) to reduce the burden on any
company introducing IPv6.

IPv4 and IPv6 address comparisons❑ IP address types
Ÿ

There are two types of IP addresses: IPv4 and IPv6. Currently,
mostly IPv4 is used.
Classification

IPv4 (developed in '81)

IPv6 (developed in 1998)

Address length

32 bits

128 bits

Address format

Ex.: 211.192.38.1

Ex.: 2001:dc2:0:40:135:72df:9e74:d8a3

Total number ofaddresses

About 4.3 billion (232)

About 4.3 billion×4.3 billion ×4.3 billion×4.3

Auto setting (complex address structure)

Security

IPSec protocols installed

Basically provided in the expansion function.

Quality control

No way of supporting

Easy to guarantee the quality❑ IPv6 advantages
Ÿ(IP addresses increased) The number of IP addresses is greatly
increased as the bit number is increased from 32 bits to 128 bits,
therefore IPv6 will be able to handle the immense impending
demand to be generated from the IoT and expanded use ofsmartphones.

Ÿ(Auto address setting) In the past, IPv4 addresses were set
manually but IPv6 allows auto setting without intervention by a
user.

Ÿ

(1:1 communication) IPv4 uses a private IP address and cannot
achieve one-to-one device communication, but IPv6 does not use
a private IP address, so it can achieve one-to-one device
communication.

Ÿ(Handset mobility) Even if a user moves to another base station,- 45 -

the IP address is not changed and service can be provided
without interruption.
Ÿ(Quality control) It is possible to classify packets depending onuser’s class and service, and guarantee quality accordingly.

Ÿ(Reduced network management costs) IPv6 does not require
address converters (Network address translation (NAT)) so it iseasy to configure the network, and costs for network
implementation and management are reduced.

Ÿ(Security) IPv4 requires additional installation of a security
function (IPSec) but IPv6 provides security as a basic unit of its
expansion function.

IPv6 transition costs

When domestic ISPs and CSPs (content service providers)
implement IPv6, we can expect that transition costs after 2014
will amount to about KRW 2.1 trillion.
- The main ISPs occupy 37.1%, small & medium ISPs occupy
21.6%, and CSPs occupy 41.3% (about KRW85.8 billion),- 47 -

which means that CSPs occupy the largest portion.

SKT, LGU+), the small & medium ISPs (77 companies) and CSPs (152 companies)
surveyed.

Ÿ(USA) As the IPv6 implementation costs can affect service types, transition
technologies, infrastructure configurations, security levels and transition time,
so also we need to discuss with interested parties and experts to derive theIPv6 implementation costs. (Jan. 2006, US Department of Commerce report,
ISPs: hardware 15%, software 15%, labor fees 70%)
