Hi, the first IPv6 /20 allocation ever has been made today: inet6num: 2001:2000::/20 netname: EU-TELIANET-20040510 org: ORG-TIC2-RIPE descr: PROVIDER Local Registry descr: TeliaSonera AB country: EU and this means that "if you have been following my filtering recommendations, this network will not be accepted right now" (the current filters had a minimum accepted prefix length of a /24). I have updated the prefix filter recommendation page: http://www.space.net/~gert/RIPE/ipv6-filters.html and urge you to check whether your filters are prepared for these large prefixes. (There is a /23 upcoming, and rumors speak of a /19 being requested "real soon now"). TODO: the "strict" filter could do some grouping for different IPv6 allocation ranges, but this is dangerous today, as we don't know how future allocations will look like. Note: ICANN just doesn't get it. They have not allocated a reasonable prefix size to RIPE (like a /8), not even a /19, but "a big chunk of 14 sucessive /23s, summing up to a /20+/21+/22" - see the list at http://www.iana.org/assignments/ipv6-tla-assignments Gert Doering -- RIPE Address Policy WG Co-Chair, keeper of the IPv6 filter list -- Total number of prefixes smaller than registry allocations: 60210 (58081) SpaceNet AG Mail: netmaster@Space.Net Joseph-Dollinger-Bogen 14 Tel : +49-89-32356-0 80807 Muenchen Fax : +49-89-32356-299
