What sites are IPv6 capable? I've been "DiG"ing for AAAA records and haven't gotten any IPv6 responses yet.

H:\>dig @4.2.2.1 AAAA www.google.com

; (1 server found)

Huh, yeah, I get the same results... probably something I'm not understanding about DNS. If you dig for ipv6.google.com it works. :)

Here's a good list of stuff: http://www.sixxs.net/wiki/IPv6_Enabled_Websites

Google, Yahoo, etc have their IPv6 setup this way because of a (small) subset of users with broken/mis-configured IPv6 setups; normally you'd have an A record pointing to the IPv4 addy, and an AAAA record for the same name pointing to the IPv6 address. However, in this situation, broken clients (i.e., clients that think they have a working IPv6 setup, but really don't) would try the AAAA/IPv6 site first, getting timeouts and frustrated. See http://www.fud.no/ipv6/ for more information.

Yeah my answer was a bit too quick.

Going to the RIPE IPv6 training thing tomorrow, let's hope I learn a bit more

My hosting provider doesn't offer IPv6 addressing yet. I should offer to help them beta test it.

You really should, I think I suggested something about that many months ago. :)

I would gladly contribute some time!

I'm ashamed to say that Itihs was the first time I've ever used "dig". It's cool :)

I'd be down with NF being IPv6 but Australian ISPs are behind what's actually needed. Not that many are there by the sounds of things.

I'll be there with bells on when my ISP goes IPv6. Hopefully I'll be involved in the transition ;)

btw, learned this morning. You have to ask google to resolve via IPv6 for yourself

More info here: http://www.google.com/intl/en/ipv6/faq.html#request

IPv6 day, June 8th I think it is, most big sites will resolve IPv6 for the entire day. This ensures users are aware that any issues getting to these places are down to them or the ISP, not the site in question.


But why is this so? I've yet to have that much IPv6 real life experience, but it's said that if a site resolves into an IPv6 and IPv4 address, the host will choose the IPv6 address first.

This means if your IPv6 stack has problems, you'll never get to google. The only way to 'test' is to specifically go to the IPv6 google site

This isn't exactly the case, what happens depends on how the client reacts. For some it may just add a slight delay while the IPv6 connection times out but other clients don't handle it so well and may never fall back to IPv4.

You can go here to test if you have broken IPv6 connectivity or not:
http://test-ipv6.com/

Also, here's what Google's www AAAA looks like when you're white listed (for those curious):
Code:
; <<>> DiG 9.5.1-P2.1 <<>> aaaa www.google.com
;; global options:  printcmd
;; Got answer:
;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 57107
;; flags: qr rd ra; QUERY: 1, ANSWER: 2, AUTHORITY: 0, ADDITIONAL: 0

;; QUESTION SECTION:
;www.google.com.                        IN      AAAA

;; ANSWER SECTION:
www.google.com.         67343   IN      CNAME   www.l.google.com.
www.l.google.com.       112     IN      AAAA    2001:4860:b007::93


Here's the site I use to browse new IPv6 sites:

Dig is a command line DNS lookup tool for *nix systems that is similar to nslookup but usually more useful.

From the MAN page about Dig:
A flexible tool for interrogating DNS name servers. It performs DNS lookups and displays the answers that are returned from the name server(s) that were queried. Most DNS administrators use dig to troubleshoot DNS problems because of its flexibility, ease of use and clarity of output. Other lookup tools tend to have less functionality than dig.

On the subject of IPv6 capable, I am wondering about the client end of capability! Can Windows XP SP2 handle v6 IP addressing? My current DHCP server provides requested IP addresses in the IPv4 format. If it provided these in the new IPv6 format, would I have to do anything to ensure my local system will accept them?

you have to run an IPv6 stack on the box.
