“.jprs” R&D Platform
What is “.jprs”
For the Internet to keep growing, we will need anenvironment to create innovations …

Experimental TLD for domain names and DNS
As demonstration experiment– For innovative technologies and productions» Difficult to implement in a production environment

For collaborative R&D with researches and businesses– Autonomous research pertaining to the Internet

Physical Geography of Japan
Hokkaido

Japan has 8 regions
Each region contains several prefecturesc.f. Japan has 47 prefectures– Tokyo, Osaka, Fukushima, Kumamoto …

ChugokuTohoku
Chubu
Kanto

Kinki
ShikokuEach region has historical, economic, Kyushu,
Okinawaand cultural feature

Such geographical features do not always pose potential danger
to all regions of Japan but specific regions in many cases

Logical Structure of Internet in Japan
Characteristic of Internet structure
Concentration of Internet resourcesin Tokyo/Osaka, which are major urban areas
Internet Exchanges (IXs),
Transit connections,
Data Centers, etc…

Osaka
Tokyo

Natural disasters that occur in/around Tokyo/Osaka
can intensely affect Internet connectivity

Recruiting Participants
Participants8 domestic regional ISPs (as of May 11, 2016)
Parent companies are/were domestic
power supply companies

Characteristics of participants’ service area
Each participant’s service area covers the “region”
where it belongs to without overlappingPower supply business had beenmonopolized in regions until Apr. 2016

ApproachWhere to install .jprs DNS servers
Into 8 ISPs’ networks

at JPRS network
at ISP network

How to direct DNS queriesRouting configuration
Using routing protocol– i.e. BGP (IP Anycast)Resolver configuration
Specifying DNS servers’ IP addresses– i.e. “static‐stub” zone type for BIND

Evaluation Method
 Continuous Internet service and Reachability of .jprs DNS
Evaluation Scenario: 2 states of environments
Before installing .jprs DNS.jprs DNS servers are locatedonly outside ISP network

After installing .jprs DNS.jprs DNS servers are locatedinside/outside ISP network
