  2. IPv4 …. YAWN!

  3. Process • Get some numbers! • IPv6 PI For Exchange Points • IPv4 PI • IPv4 PI will go away very soon indeed!

  4. Do v4 prefix exchange over v6 transport? • You still need an IPv4 next-hop • Process separation is desirable • Assumption that next-hop can deliver 4 *and* 6 is possibly flawed • Troubleshooting?

  5. RFC 1918 IPv4 • URPF • Duplication • Reverse DNS • ICMP failure • Troubleshooting ?

  6. Just do v6 peering at new exchanges? • Makes new exchange unattractive or unviable • Exchange is a neutral catalyst for good of internet including v6 deployment

  7. Just don’t make any new exchanges • Unappealing • The bits of the world without exchanges will benefit enormously from an exchange

  8. Save some IPv4 for IXPs? • Hold an additional /16 from the last /8 for IXPs • We define IXPs in ripe document already • … Discuss ? • To be taken to APWG on Thursday if support.
