Available characters, variants• Available characters– Hiragana, Katakana, Kanji• The selection is based on JIS (Japanese Industry Standard)– Several marks regarded as a Kana or a Kanji• Variants– No variants defined– In our draft: “… However in the name, especially inthe proper noun, those aren't interexchangablebecause of their own identity. Actually, there is no
official Kanji variants table in Japan.”

Unifying hostname of .JP DNS servers• Hostnames of .JP DNS servers are unified to[A-F].dns.jp on June-August 2003
– Primary server• A.dns.jp: operated by JPRS

– Secondary servers (*)IPv6 ready• B.dns.jp: formerly ns0.nic.ad.jp• C.dns.jp: formerly dns0.spin.ad.jp• D.dns.jp: formerly ns0.iij.ad.jp(*)• E.dns.jp: formerly ns.wide.ad.jp(*)• F.dns.jp: formerly ns-jp.sinet.ad.jp(*)• To allocate the payload for ‘more’ IPv6 glue
• To simplify the relation of delegation– “dns.jp” zone itself is now delegated to [A-F].dns.jp

Japan Registry ServiceE.dns.jp• Formerly, ns.wide.ad.jp– Operated by WIDE Project• Moved the physical location– Outside of Tokyo (Osaka area)• Changed the IP address and AS number– Performed at the same time the unification ofhostname– Provider independent (PI) address and its own ASnumber• Detached from WIDE Internet• Only for DNS infrastructures• To acquire multiple transits

E.dns.jp (cont.)• This is a pilot case to enhance robustnessof .JP DNS service– To provide extra redundancy to survive .JP DNS
service in the case of serious disasters in Tokyo– Especially, preparing to the electric power crisis of
the summer of this year (by the scandal of electricpower company)• But, in Japan, this summer is very cool… ☺
• But, serious power outage occurred in NY– This is an object lesson

Japan Registry ServiceFuture plans• We will change IP address and AS
number of A.dns.jp (primary server) for‘critical infrastructure’– Critical infrastructure is defined by APNIC• http://www.apnic.net/info/faq/criticalinfrastructure-faq.html– country code TLD (ccTLDs) nameservers• We plan to introduce anycast
technology onto .JP DNS servers– To enhance robustness of DNS service
