It's update your IPv6 filters time:

http://www.arin.net/reference/ip_blocks.html

8<----------------------------------------- IPv6 Assignment Blocks CIDR Block 2620:0000:/23 ----------------------------------------->8 Expect blocks in between /40 and /48 there.

Filter recommendation document updated.

Could you also add blocks like 2800::/23 from LACNIC issued Nov 2005 by IANA?

Does the policy really permit /40.../47 assignments?

The only thing I found so far is [1] which really only defines the <=48 end. It's talking about _at least_ a /44 reserved for future growth and it says "When possible, [subsequent] assignments will be made from an adjacent address block.". Considering what we see with v4 PI (direct assignments) today and had seen with /8 PA and an undefined ("open") other end in ARIN policy I wouldn't trust any >=40 rule being the maximum for this block. I have so far decided to use (also see [2]): ! + ARIN PI (chose whatever one you think is worse) !ipv6 prefix-list ipv6-ebgp-strict seq 135 deny 2620::/23 le 128 ipv6 prefix-list ipv6-ebgp-strict seq 135 permit 2620::/23 ge 32 le 48 Happy weekend. /bz References: [1] http://www.arin.net/policy/nrpm.html#six582 6.5.8.
