Re: 30 second ipv4 redesign?

BGP route space is not an issue, we went passed that ages ago the issue is IPv4 only has space for 16bit or 65535 AS numbers and we are using 61140 advertising 724500 routes (agregated to just under 400k in the core)

we went over the 512k routes a few years back and no-one missed a step TCAM tables on modern routers have space for 2048k entries, which should keep us going for some while yet.

Talking v6 adoption, there are 52k routes and 15320 ASes in the current BGPv6 table and the v6 header has room for 32-bit AS numbers or upto 4294967295 ASes
