Martin List-Petersen, AirWire

  1. 1. ISP IPv6 deployment Martin List-Petersen Airwire martin@airwire.ie
  2. 2. Migration and pitfalls ● 6to4 ● Teredo ● 6in4 (Tunnel Broker Services) ● PPPoE ● Native
  3. 3. Tunneling pitfalls ● Unpredictable latency with 6to4 and teredo ● 6in4 tunnels have predictable latency, but static provisioning of 6in4 tunnels is cumbersome
  4. 4. 6to4 traffic
  5. 5. Teredo traffic
  6. 6. PPPoE ● Manageable from an ISPs perspective (package/service management) ● IP6CP + DHCPv6 for dynamic configuration of endpoint ● Exactly the same as PPPoE for IPv4
  7. 7. Native ● Optimum from a networking perspective ● Circuit separation/security ? – Could be implemented at ethernet level (VLAN etc.) ● Package/Service Management ? – Can be applied locally, but not really easily manageable in a large scale environment
  8. 8. Pitfalls on the consumer side ● Very few routers available with IPv6 support ● Inconsistency of router vendor implementations ● Currently no DHCPv6 support on our platform ● Windows XP needs IPv4 transport for resolving DNS ● Non-IPv6 capable consumer routers block automatic roll-out.
  9. 9. Pitfalls on the carrier side ● All our carriers deliver IPv6 ● Some carriers still don't have a full-table and the implementation of their peering agreements can be unfortunate. ● Some carriers still have to learn, not to take their IPv4 filtering policies and “just” to apply them to IPv6.
  10. 10. Where is the killer app ? ● Various websites have enabled IPv6 ● We are Google IPv6 weblisted ● When Google end of last year enabled YouTube, IPv6 skyrocketed
