JP Domain Name
Registry ReportJapan Registry Services Co.,Ltd.

Introduction

As the Internet is being used in increasingly diverse areas of society, the need fordomain names is growing and the area of domain name use is getting broader. With
this background, the total number of registered JP domain names topped 1.45 million
in January 2017. Especially, about 390,000 names are registered under “co.jp,” making
it the most registered category in the Organizational Type JP Domain Name, thedomain name space categorized by organizational type of registrants. 97% of
publicly-listed companies in Japan have already registered “co.jp” domain names,
which indicates that many companies regard “co.jp” as the suitable domain forcorporate websites.
In 2016, JPRS made progress on the launching and developing new services toimprove the security and reliability of domain names in order to meet the increasing
demand for domain names. As part of this effort, it started the JPRS Digital Certificates
Issuance Services.
With respect to the trend of the global domain name industry, the New gTLD Programof ICANN*1 enabled a number of new gTLDs to start operation one after another. Morethan 1,200 new gTLDs emerged on the Internet by the end of 2016, which led to thelaunch of websites with those new gTLD domain names.
On the other hand, various challenges have continued to threaten the Internet
infrastructure such as DDoS attacks exploiting the mechanism of the domain namesystem (DNS) and detection of vulnerabilities in DNS software.
As a company supporting the basis of the Internet society through domain names and
DNS, JPRS is striving to make the Internet safe for everyone to use. To this end, JPRS
promptly provides information and deals with risks and challenges related to domainnames and DNS as they arise. JPRS also actively contributes to discussions of global
issues and conveys relevant information to the communities in Japan.
In addition to the above, JPRS is committed to its ongoing operations to improve JP
domain name services, develop systems, and carry out promotional activities tofacilitate the use of JP domain names and deliver greater value to users.
The management and administration of JP domain names require a high level ofcommitment to enhancing the public interest and getting ahead in the competition.
Recognizing this vital nature of its services and influence on society, JPRS carries out
its tasks and publishes the annual “JP Domain Name Registry Report” on its
management and administration of JP domain names.
JPRS will continue to ensure that JP domain names remain useful and contribute to thedevelopment of the Internet society.

Goal of JPRS as the JP Domain Name Registry

Our main objectives as the registry are: to continuously improve the value of JP domain names; to gain stronger
support from the local and global Internet community; and to provide domain names as well as management andadministration services that contribute to society in an environment where JPRS competes and collaborates withother registries of TLDs*1 and similar service providers.
JPRS defines the following as the core concepts for the registration and administration of JP domain names.
Reliability: establishing domain name space with the public trust
Stability: operating and administering the stable domain name system (DNS)
Usability: providing accessible domain name services which meet users' needs
Fee Performance: providing services at reasonable fees
With the mission of supporting the Internet infrastructure, JPRS considers it important to ensure reliability andstability while pursuing a good balance with usability and fee performance.

International Relations

1.Participation in ICANNICANN is a private non-profit organization established in the UnitedStates in 1998 to coordinate globally the resources underpinning theInternet, such as domain names and IP addresses.
Since its foundation, JPRS has been actively participating in theorganization of ICANN and various policy discussions, and supporting
the facilitation of Internet resource management led by the private
sector, with ICANN playing the central role. In 2002, JPRS signed a“ccTLD*1 Sponsorship Agreement” with ICANN, and has since been

By participating in various organizations established within ICANN, as well as by giving presentations andinformation exchanges at various sessions, JPRS participates in policy development andimplementation-planning to cope with issues facing ICANN and registries. Also via ICANN, JPRS is sharing its
experience in JP registry operations with the global community, thereby contributing to the development of theInternet as a whole.
ICANN holds three public meetings each year in different regions of the world to enable global stakeholders toparticipate in person and discuss policies and rules for Internet resource management. In 2016, ICANN held its
55th meeting in Marrakech, Morocco in March, the 56th meeting in Helsinki, Finland in June and the 57th
meeting in Hyderabad, India in November.
With the participation of numerous parties interested in ccTLD and gTLD*2, ICANN has always functioned as animportant forum for information-sharing and discussion on issues on policies and governance concerning domainname management. In addition, Supporting Organizations (SOs) and Advisory Committees (ACs) actively held a

01 Registry Activities(2) IDN Variant TLD Program
The IDN*5 Variant TLD Program is a series of activities to develop Label Generation Rules (LGR) for the rootzone and aims to establish procedures to add non-ASCII scripts to the root zone.
The following two panels are engaged in the activities of the IDN Variant TLD Program:
1. Generation Panel (GP)Each GP is composed of key figures of each language community and experts in linguistics and domain names.
Each GP creates a proposed LGR for a given script and is organized for each script to be added in the root zone.
2. Integration Panel (IP)
IP is a panel of experts in character encoding or IDNs and is tasked with integrating rules developed by the GPs
into a consistent set of LGRs.
The IP was established in 2014, and several GPs for different scripts were formed in 2015. Hitherto, the Arabic
and Armenian LGRs have respectively been proposed, and other Asian language communities are also making
progress.
The cultural community that uses Han (Kanji) script includes the Chinese, Korean and Japanese communities,
so it is necessary to develop the LGRs that are consistent across those language communities. Therefore, theJapanese community has been working on its LGR in consideration of such necessity. The study is being
conducted in the Japanese Generation Panel (JGP) involving experts representing the Japanese language
community, linguists and registry experts, with JPNIC and JPRS serving as the secretariat. Hirofumi Hotta of
JPRS is leading the initiative as the chair, and Yoshiro Yoneya as well as Yoshitaka Murakami are participating as
members to contribute their expertise gained through designing, providing and operating the Japanese JP
Domain Name services and knowledge related to trademarks.
The Japanese, Chinese and Korean GPs will continue to coordinate with each other and then respectively
propose the LGRs for their own scripts to ICANN. The three-party coordination and the arrangement with the IP
were originally planned to be complete by mid 2015, but development of the Chinese and Korean LGRs andcoordination with ICANN are still under way. Accordingly, the JGP will continue to collaborate with the Chineseand Korean GPs, IP as well as ICANN to consider the Japanese LGR in 2017.

01 Registry Activities(6) Root KSK Rollover Design TeamDNSSEC deployment in the root zone began in July 2010. It is specified that a rollover of the Root Zone Key
Signing Key (KSK) should be carried out when necessary or every five years*10. In February 2015, ICANN set up
a design team (KSK Rollover Design Team) that was tasked with planning the Root Zone KSK rollover. The teamproduced and published for comment a document that defined the roles of the related parties and the rollover
process. The draft was approved by the ICANN Board, which was followed by publication of the finalized version
in March 2016*11. Yoshiro Yoneya of JPRS participated in the Design Team as a member.
The document is intended for the first KSK Rollover and proposes that the signature algorithm and key size
should be maintained; the KSK should be rolled over on a 90-day window that is set for the Zone Signing Key(ZSK) rollover; and a fallback should be performed in case of emergency.
The root KSK rollover will be conducted from July 2017 to March 2018.

(7) RA Spec11 Security Framework Drafting TeamThe new gTLD Registry Agreement (RA) requires the registries to periodically assess whether the registereddomain names are being used for malicious purposes and provide statistical reports to ICANN*12.
The report is called “Spec11 3b” or simply “Spec11,” after the relevant part in the RA. ICANN established a teamto draft a guideline for the new gTLD registries (Spec11 Security Framework Drafting Team) in July 2015, so that
ICANN could respond to the inquiries from the registries as to how they should implement the Spec11. Currently
the Drafting Team is drawing up a document containing the points to be considered by the new gTLD registries.
The Team consists of three groups, namely, the Registry Group, the Registrar Group and the GAC*13 Group.
Yoshiro Yoneya of JPRS is on the Registry Group.
In the Team, mainly the Registry Group prepares the outline of the document, and then the Registrar Group andthe GAC Group review the draft.
Although development of the draft was behind schedule, currently it is planned to come out for public comment in2017.

IETF 95(1) precis WG
Internationalized identifiers generally refer to identifiers containing non-alphanumeric ( internationalized)
characters that uniquely identify domain names, email addresses and website addresses on the Internet.
To use internationalized identifiers, preprocessing is necessary to unify or normalize character cases andcompatible characters so that character strings can be matched up correctly.
In IETF, the way for standardization had been discussed in the precis WG*3 set up in June 2010. precis consistsof a framework that defines the outline of the processing order, mode and the individual options, along with theprofiles that define the options in the framework to be used in each protocol.
The guideline co-authored by Yoshiro Yoneya of JPRS to complement the framework was issued as RFC 7790 in
2016.

01 Registry Activities(2) dnsop WG
The name of the dnsop WG*5 derives from DNS Operations, and aims to compile a guideline for DNS operationin general, including administration of DNS servers and registration data.
JPRS has actively participated in the dnsop WG with its expertise as the JP DNS operator to point out the
ambiguity in the DNS protocol, present the issues caused by misconfigurations of DNS servers and discuss theoperational method of DNSSEC. JPRS also played an active role in developing RFC 4074 and RFC 7719 as an
author.
In 2016, Kazunori Fujiwara of JPRS, Mr. Akira Kato of the Graduate School of Keio University and Mr. Warren
Kumari of Google Inc. in the U.S. made progress in standardizing the proposals that they had co-authored to use
DNSSEC as a method to streamline name resolutions and as a countermeasure against random sub-domain
attacks (DNS water torture attacks). These proposals are now under final review in the dnsop WG. Following thestandardization within the WG, the documents will be submitted to IESG*6.
Kazunori Fujiwara of JPRS, Mr. Paul Hoffman of ICANN and Mr. Andrew Sullivan of Dyn Inc. in the U.S., who isalso the IAB chair, co-authored the DNS Terminology ( glossary ) , which was then issued as RFC 7719 in
December 2015. Since then, efforts have been made to collect words for the terminology and to makesuggestions for improvement.
Furthermore, Fujiwara pointed out the defects in the name resolution algorithm defined in RFC 1034 as well as
RFC 2181 and presented a suggestion for improvement. However, some said that his proposal required carefulconsideration, and so the WG agreed to continue discussing the issue.

The regext WG*7 is a working group formed in March 2016 as a result of integration of the eppext WG organized
for functional extension of EPP*8 and the weirds WG*9 set up to consider the standardization and functional
extension of RDAP. The regext WG is also tasked with discussing the registry-related protocols in addition to theconcerns of the predecessor WGs.
Following the new gTLD application round held in 2012, standardization of data escrow*10 also went ahead.
JPRS contributed to the standardization activity as one of the co-authors of the related Internet Draft. The
Internet Draft had not been issued as an RFC by the end of 2016. The authors therefore called on the regext WG
to include data escrow standardization in its scope.

for the Future

JPRS has constantly worked to strike a proper balance among reliability, stability, usability and fee performance,
which constitute the basis of JP domain name registry services and JP DNS operation, while also improving
each of the four values.
In 2016, JPRS fully migrated its application processing environment for JP Registrars into a system operating
under the authentication method based on digital certification, with a view to further improving the security andreliability of its service. It also made progress in studying and developing the new service to enhance the security
and reliability of domain names, and started the JPRS Digital Certificates Issuance Services in April.
JPRS also tapped into its expertise as the JP domain name registry to provide information related to domainnames and DNS and promote understanding of industry trends at events and meetings held in Japan andoverseas. Its continuous collaboration with various related communities and active contributions including theVWDQGDUGL]DWLRQRI,QWHUQHWWHFKQRORJLHVSURYHGIUXLWIXODVLWSXEOLVKHGD-DSDQHVHJXLGHWR,&$11·VILQDOUHSRUWon the name collision issue that resurfaced as a concern upon the introduction of new gTLDs, and had the RFCs
issued with its engineers as co-authors.
The year 2016 saw incidents threatening the stable operation of the Internet, such as a number of urgent andserious DNS software vulnerabilities and large-scale DDoS attacks exploiting the mechanism of DNS. JPRS
collaborated with other relevant organizations and responded to these problems by alerting the community with asummary of the incidents as well as countermeasures against them.
Recognizing the growing necessity of Internet-related education in schools, JPRS has distributed a free booklet
on how the Internet works to educational institutions across Japan for seven years in a row as part of its
Internet-related educational support activities. As a result, the number of copies distributed in these seven years
exceeds 200,000. JPRS also provided domain names free of charge at a website creation contest for junior andsenior high school students.
The Great East Japan Earthquake that occurred in 2011 has added further weight to need for the reliability andstability of the Internet infrastructure. To ensure service continuity and improve the operational infrastructure
against this backdrop, JPRS enhanced its ability to restore service by using the disaster recovery site establishedin the Kansai area to fully duplicate the operation base and registry system. It also compiled manuals andconducted test drills along the same lines. Furthermore, JPRS conducted a joint research with eight telecom
carriers backed by electrical power companies on continued use of the Internet in case of a large-scale disaster,using “.jprs,” a new gTLD for research and development.
Going forward, JPRS plans to reinforce the disaster recovery capability of all of its services by implementing amore robust recovery scheme. It will also consolidate its operational infrastructure to improve the systemmonitoring function and security. In addition, JPRS will continue to enhance the security and reliability of its
services and disseminate information on DNS technology by issuing advisories on vulnerabilities and security
alerts to ensure the stable operation of DNS.
As the registry of JP domain names, JPRS will continue its efforts to provide better and stable services.

38 Registry ReportAbout JPRSJPRS provides domain name services such as domain name management, administration anddistribution, and also performs domain name system (DNS) operations. In addition, JPRS is
engaged in research and development of various Internet technologies.

Domain Name Management and Administration
JPRS manages and administers domain names. In particular, JPRS plays an important role as the registry of JP
Domain Name, or domain names of Japan. You may have seen addresses for websites and emails such as“http://○○○.jp” and “△△△@○○○.jp.” JPRS manages and administers a part of these addresses, namely,
strings in the form of “○○○.jp.” Domain names are the key to accessing the Internet. JPRS is constantly improving
its services so that JP domain names will continue to assist the activities of all kinds of Internet users, including
companies, organizations, and individuals.

DNS Operation
DNS (domain name system) is a system for identifying computers connected to the Internet using domain names, so
it is sometimes referred to as the “phone book for the Internet.” If DNS were to fail, people would not be able toaccess websites or exchange emails using domain names. To prevent such a catastrophe, JPRS has established a
24/7/365 system to ensure stable operation of the “JP DNS” for managing JP domain names.

R&D of Internet Technologies and International Activities to Support the Internet
JPRS takes an active part in the research and development of advanced technologies to promptly respond tochanges in the Internet environment and social needs. Specifically, JPRS engages in standardization activities
through contributing to the internationalization of the identifiers used for protocols, devising methods for resolving
issues concerning DNS operations and submitting proposals to standardize registry technologies. JPRS actively
publishes the results of these activities and shares information at IETF and other meetings to contribute to the
network society.
