IP Anycast for .JP DNS distribution• A.dns.jp and D.dns.jp are now in IP Anycast mesh
– A.dns.jp, by BGP anycast– D.dns.jp, by IGP anycast– Details are described later• We completed system buildup, and applied for thechange of nameservers information (IP address) toIANA• Schedule– Jan 19: zone data of jp and dns.jp were changed and‘ccTLD modification form’ was sent to IANA
– Jan 22: receipt of the “change request” came from IANA
– Jan 23: JPRS confirmed the change request• Some further operations are needed to be done by IANA
– For example, communication with DoC (US government)• The change is expected to be effective on the rootserver in afew days

Future plans• Worldwide distribution ?
– In Europe, Asia, …. ?

• IP Anycast of other .JP nameservers for
JP DNS distribution ?
– RFC 3258 says, “... organizations
implementing these practices should always
provide at least one authoritative serverwhich is not a participant in any shared
unicast mesh.”– At least one nameserver should remain ‘notanycasted’
