Project: IPv4 shortage AMS-IX

Samenvatting

The AMS-IX will probably run out of its /22 IPv4 address range on the Internet Peering VLAN in 2016. When this happens no new routing devices can join the IPv4 AMS-IX Internet Peering VLAN anymore. To double the current /22 to a /21 IPv4 range the AMS-IX will have to become a LIR by becoming a member of RIPE NCC. If the AMS-IX should decide to do this it would have to act quick as the RIPE NCC will no longer give out /21s to LIRs when the final /8 IPv4 range will start to be handed out. This will probably start to happen in the coming few months. This solution should be used to buy more time so better and more permanent solutions can be developed. A promising more permanent solution is a new technique described in RFC 5549 which enables MP-BGP to advertise IPv6 next hop addresses for IPv4 destinations. This would eliminate the need for IPv4 entirely on the AMS-IX Internet Peering network. In this document I describe 3 ways how RFC 5549 could be implemented. These are: • native inter-protocol forwarding1 • a translation table managed by the forwarding table • a translation table managed by the routing deamon There is now a working proof of concept which utilizes a translation table managed by the routing deamon. This proof of concept shows that RFC 5549 has potential as a permanent solution to the IPv4 shortage on the AMS-IX Internet Peering VLAN. Further research on RFC 5549 is needed. For example there is a problem with traceroute in the current proof of concept. This document describes a theoretical way of solving this problem. The AMS-IX could use this proof of concept and this research report to create a demand for this solution with its clients. The clients of the AMS-IX should then proceed to ask their routing vendors to implement RFC 5549 in their routing devices.
