Re: new ipv6 features in latest airport and time capsules



James,

Thanks for the summary.  This is very useful information.

I've been using the new Airport Extreme for a few weeks now and have been very pleased with the new features so far, compared to the older Extreme I had been using for the last few years. For me, the upgrade was well worth the investment.

For IPv6 I've used both manual and automatic (6to4) tunnels, and both worked without a hitch, and were very easy to configure. For anyone else that wants to try this (tunnels) I would strongly recommend a manual tunnel to one of the free tunnel brokers (Hurricane Electric is probably the best) since that is going to be more robust than 6to4 (as long as your public IPv4 address is fairly static) when interacting with the the IPv6 Internet at large.

Since MacOSX doesn't support DHCPv6, I haven't had a chance yet to test those features on the new Extreme.

Other things I really liked (compared to my much older Extreme):
- 802.11n, of course
- seeing my MacBook Pro connect at 300 Mb/s
- the ability to configure a separate "Guest" network (SSID), to keep all your house guests separated from your home network and systems, with support for older encryption types that are more compatible with older PCs
- the reporting and graphing of status on AirPort Utility


The disappointment that remains is Snow Leopard (10.6) seriously broke IPv6 functionality when it switched to using mDNSResponder internally and now throws away all but the first DNS response to any query, so you almost always lose your AAAA responses in DNS queries. So I do a lot of my IPv6 testing using my 10.5 system, to make sure I'm always using IPv6 when available.

everyone--

One of the new features in the latest round of AirPort Extreme and Time Capsule products that Apple quietly released earlier this month is improved IPv6 capabilities. This wasn't announced in any press releases, since these new features are still intended primarily for advanced users only, i.e. mainly the subscribers of this list and leading IPv6 service providers.

I'm going to describe briefly the improvements here.

+ support in the DNS resolving server for IPv6 forwarding addresses.

+ new DHCPv6 client in IPv6 host mode:
 - supports both stateless and stateful DHCPv6;
 - requests DNS server IPv6 addresses and merges with IPv4 addresses.

+ new IPv6 "native router" configuration mode:
 - available only in IPv4/NAT mode;
 - not available when WAN is configured for PPPoE (sigh);
 - manual IPv6 WAN configuration is optional;
 - DHCP6 client requests prefix delegation, advertised on LAN bridge.

+ stateless DHCP6 server:
 - available in both IPv6 tunnel and router modes;
 - advertises the IPv6 address of the integrated DNS resolver;
 - no stateful DHCP6 service supported.

As improved IPv6 capability is A New Feature, it will not be made available in firmware maintenance releases for earlier AirPort Extreme/Express and Time Capsule products.

The IPv6 features in AirPort and Time Capsule are mainly for the purpose of supporting advanced users of IPv6 networking and for participation in engineering trials of native IPv6 service by residential Internet service providers. If you're an IPv6 service provider and you discover interoperability problems, then I'm power- motivated to get them fixed as soon as possible. I'm under some time pressure to get everything related to this feature nailed down and solid, so please hurry if you can.

Please file problems you discover at http://bugreport.apple.com for best results. If that doesn't work for you, then email me directly, but everyone will be happier if you go through the bug reporter.
