What if a /8 was set aside from one of the reserved pools, and each ASN got one /24 out of that /8 automatically and predictably (8 bits net + 16 bits of ASN = 24 bits) when getting an ASN?
This is just the "GLOP" multicast address assignment idea of RFC 2770 http://www.ietf.org/rfc/rfc2770.txt where a /24 is assigned automatically. It would add 30% to the number of BGP address blocks pretty much automatically. Regards Marshall Eubanks
Since you have to connect to two or more providers to get an ASN, and since the whole reason to have an ASN is to inject things into the DFZ it doesn't seem like it would increase routing table size by a huge amount. It would eliminate one whole paperwork/justification step (for your first address allocation). For subsequent allocations there is an example (that /24) of how efficiently the ISP uses the space. -- Leo Bicknell - bicknell () ufp org - CCIE 3440 PGP keys at http://www.ufp.org/~bicknell/ Read TMBG List - tmbg-list-request () tmbg org, www.tmbg.org
