IPv6 Day Has Started

[+] ay|14 years ago|reply

BTW in case it is a non-event, you can post fun IPv6 addresses that you notice.

Here's some. Check the AAAA for:

www.facebook.com www.luns.net.uk www.cisco.com

EDIT:

I meant, check the literal IPv6 addresses that correspond to these hostnames. I'll put emphasis so it is more visible :)

2620:0:1c08:4000:===face:b00c===:0:1, 2a01:8900:0:1::===b00b:1e5===, 2001:420:80:1:===c:15c0:d06:f00d===

EDIT2:

And while you're at it - maybe enable AAAA record for your site and give it a whirl! (and come up with some more creative IPv6 addresses in the process!) Thanks to guylhem for reminding about this.

sprint.net has a pretty nice one. Theirs isn't an IPv6 day exclusive either. Kind of amusing address for a telecom company...

[+] guylhem|14 years ago|reply

I use dead:beef and feed:cafe for my 2 small subnets on a /48 I got from he.net, because it's easy to remember.

Of course, if you really want to identify your allocation, setup reverse dns. To do it the easy way go to afraid.org. They offer a great free service, IMHO better than dyndns.

my site jcs.org has been dual-homed for quite a while.

Wonderful. I switched from an hetunnel to native ipv6 on my linode, and it actually reduces latency over the ipv4 connection:

    [~] 0 (jon@snowball2)
    $ ping itchy.jrock.us
    PING itchy.jrock.us (66.228.52.205) 56(84) bytes of data.
    64 bytes from itchy.jrock.us (66.228.52.205): icmp_req=1 ttl=49 time=59.4 ms

And then with native ipv6:

    [~] 0 (jon@snowball2)
    $ ping6 itchy.jrock.us
    PING itchy.jrock.us(2600:3c00::f03c:91ff:fe93:50b0) 56 data bytes
    64 bytes from 2600:3c00::f03c:91ff:fe93:50b0: icmp_seq=1 ttl=246 time=36.6 ms

Pretty good!

During one of the last FOSDEMs (fosdem.org) we noticed similar thing - the RTT to google.com was slightly smaller over IPv6 than IPv4.

But it's a mixed bag. All one can conclusively say that the average patient temperature in the hospital is pretty close to normal.

My web site has been open for ipv6 business for a while. At home today, I installed tunneling software on my openwrt box, and it's working with comcast. Once I found the right set of instructions it went smoothly (https://wiki.xkyle.com/Comcast_IPv6_on_Openwrt). I can see unicorns now: http://ismyipv6working.com/

[+] justincormack|14 years ago|reply

Yeah, installing a tunnel went pretty smoothly, but finding the home router documentation was not that easy, this has details for O2 broadnband in UK http://blog.technologyofcontent.com/2011/05/this-blog-is-now...

Lovely - thanks for the link! added it to my mini-directory on ipv6-test.net

Interesting how South America and Africa have absolutely zero traffic reported. I thought at least Africa, with it's shortage of IPv4 addresses, much like Asia, would have picked up on IPv6 to a larger extent than the "IPv4 wealthy" nations in the industrialized parts of the world.

Anyone have any theories? Ideas?

[+] rwmj|14 years ago|reply

99.99% of people won't have an IPv6 connection and can't be bothered to set up a tunnel. However it's still possible to play with IPv6 on your home network, and relatively simple too if you have at least one Linux box:

[+] ay|14 years ago|reply

The point of the day is to ensure that enabling AAAAs on the server side does not break the world. clientside IPv6 connectivity is a nice plus, but optional.

A couple of corrections:

1) ULAs are normally not routable over the internet. Though of course blocking them explicitly would not hurt.

2) depending on the RFC3484 configuration on the hosts, this "IPv6" might break connectivity to dualstack sites.

Please - go to tunnelbroker.net (or sixxs.net) and get yourself a tunnel - it is not that difficult, really.

[+] mrcharles|14 years ago|reply

The large company I work for (~5000 people worldwide) doesn't appear to support any of this. Attempting to reach ipv6day.org gives the message "No DNS records."

Sites that already had IPv4 records work.

[+] drdaeman|14 years ago|reply

I have fully working IPv6 connectivity (10/10 by test-ipv6.com metrics), but ipv6day.org still fails for me. It seems that the problem is that there're no A/AAAA records:

    $ host -t AAAA ipv6day.org 
    ipv6day.org has no AAAA record
    $ host -t A ipv6day.org  
    ipv6day.org has no A record
    $ host -t MX ipv6day.org 
    ipv6day.org mail is handled by 20 mail2.consulintel.es.
    ipv6day.org mail is handled by 30 dns1.consulintel.com.
    ipv6day.org mail is handled by 10 mail.consulintel.es.
    $ host -t SOA ipv6day.org 
    ipv6day.org has SOA record ns1.euro6ix.com. dnsadmin.consulintel.es. 2010120100 86400 7200 2592000 172800

I've just gone with the common ones.

[email protected] [~]# host jacen.kly.no jacen.kly.no has IPv6 address 2001:16d8:eea2:30::dead

[email protected] [~]# host civ5.flexd.net civ5.flexd.net has address 178.255.146.39 civ5.flexd.net has IPv6 address 2001:16d8:eea2:30::beef

[email protected] [~]# host caedus.kly.no caedus.kly.no has IPv6 address 2001:16d8:eea2:30::daad

IPv4 users hit a IPv4 varnish which redirects to another varnish on the proper server (woo, double). IPv6 hits the proper server varnish directly. Seems to work great from everywhere!

Would be very interesting to hear what the HN folks' experiences are with the whole v6day thing. Hopefully it should be a non-event, but interesting to know anything otherwise.

[+] dangrossman|14 years ago|reply

Comcast came by and ripped the cable off the pole at just about midnight exactly. I've had no internet connection since and have no idea if it'll be back on before the day is over. I'm on HN through my phone.

Coincidence I'm sure.

[+] guylhem|14 years ago|reply

It's just a good opportunity to configure services and test how it works. Personally I had never touched anything ipv6 related before this spring. There was no real reason to (blame me). Now seems a good moment.

[+] smackfu|14 years ago|reply

Can anyone tell me why http://ipv6day.org is failing after a lengthy timeout, but http://www.ipv6day.org works? There are links to the non-www version in this article, so I assume it worked at some point.

Edit: Actually, I think SANS just linked to the wrong site. It should be http://www.worldipv6day.org/

This Firefox plugin lets you see the IP you connect to which is useful to see if you get IPv6 https://addons.mozilla.org/en-US/firefox/addon/showip/?id=59...

The bbc is odd, as www.bbc.co.uk has ipv6 address 2001:4b10:bbc::2 but Firefox only connects to ipv4.. [edit] finally connected on ipv6 after a restart...

[+] there|14 years ago|reply

from what i remember, that add-on just tries to resolve hostnames that it sees, it doesn't actually show you whether you connected to that specific ipv4 or ipv6 address.

[+] madao|14 years ago|reply

Netregistry.com.au also joined in on the ipv6 fun, funny their main competitor melbourneIT seems not to be interested in it.

[+] jarito|14 years ago|reply

Looks like www.rackspace.com is IPv6 now. I can't route to it since I'm on TimeWarner, but it seems to have a AAAA record.

[+] skimbrel|14 years ago|reply

My HE tunnel is working great! Looks like my latency to Google is the same as it is on IPv4.

[+] lostbit|14 years ago|reply

Some sites that don't have AAAA DNS today:

[+] jrockway|14 years ago|reply

Resolving AAAA records doesn't have much to do with IPv6 connectivity. The whole point today is to see what happens when clients receive AAAA records in addition to A records. If a misconfigured client thinks it can use IPv6 but can't, then the existence of that AAAA causes problems.

[+] cmeiklejohn|14 years ago|reply

Awesome, since Google via IPv6 is not responding for me now and has been all day.

ping me if you want any help with the debugging. I might be a bit busy but will try to help.

Either my gmail or work address could work as XMPP contact.

ycombinator.com (67.23.12.57) is up via IPv4! ycombinator.com doesn't have an IPv6(AAAA) DNS Entry!

I'm going to try to see if I can get IPv6 working for my linodes.

If you're in Fremont, Newark, or Dallas, it's pretty easy... Just open a ticket (I hear there's actually a button now) and reboot.
