Subject: /20 allocated - update your BGP filters!

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
