I'm in wellington on the 27.252.128.0/22 subnet. I have noticed there is now IPv6 via dhcpv6.

I'm using an edgerouter-lite, and thought id share my config, and start a thread to discuss any teething pains.

i had a wee bit of trouble with routing, but after configuring it to use eui64, it seemed to work. annoyingly vyatta wouldnt let me commit that config because the ipv6 address was already present.

Remember: if using ipv6, dont forget to properly firewall. especially if you're advertising onto lan, as there is no nat (internal devices are externally reachable).

I'll check out how the performance is. Ive heard people have been having a lot of dns issues in wellington lately, perhaps due to the rollout?

dns can sometimes be unpredictable when ipv6 is in use because it alternates between giving you ipv4 A records and ipv6 AAAA records.
My DNS has been pretty solid because rather using vodafones notorious server, i have unbound running on my router, giving secure, reliable, fast resolving. for those on ubiquiti or openwrt, id recommend this.

The main issue here in wellington appears to be DHCPv4, hopefully now ipv6 may provide a fallback, and possibly more reliability, at least in cases where theres problems on the v4 side

The prefix is 2407:7000:f01c:0:[duid]/64

where duid is based on your mac address
