Surfing with IPv6

My DSL carrier (and as far I know no Spanish ADSL carriers) has IPv6 available so my only chance to join IPv6 Launch Day is to create a tunnel to a IPv6 service provider. I've choose the well known Hurricane Electric Tunnel Broker free service.

Easy steps using Ubuntu:
- Sign-in.
- Create your tunnel connection towards your public IPv4 address (Note: You will need to allow HE to ping your router in your firewall configuration).
- Configuration following this guide: http://davecoyle.com/documents/ubuntu-ipv6-he-tunnel.html
- Add the IPv6 DNS server at your /etc/resolv.conf file. In this cases is: nameserver 2001:470:20::2
My suggestion, and for the sake of the test, is to use only this DNS server.
And test!

How my IPv6 tunnel interface looks like:

# ifconfig he-ipv6 he-ipv6   Link encap:IPv6-in-IPv4            inet6 addr: 2001:470:1f08:16b::2/64 Scope:Global           UP POINTOPOINT RUNNING NOARP  MTU:1480  Metric:1           RX packets:24393 errors:0 dropped:0 overruns:0 frame:0           TX packets:15097 errors:0 dropped:0 overruns:0 carrier:0           collisions:0 txqueuelen:0           RX bytes:30140949 (30.1 MB)  TX bytes:1460976 (1.4 MB)

And the local interface. Now we have the new localhost IPv6 address ::1 (In IPv6 this is the equivalent of 127.0.0.1).

lo        Link encap:Local Loopback            inet addr:127.0.0.1  Mask:255.0.0.0           inet6 addr: ::1/128 Scope:Host           UP LOOPBACK RUNNING  MTU:16436  Metric:1           RX packets:1043 errors:0 dropped:0 overruns:0 frame:0           TX packets:1043 errors:0 dropped:0 overruns:0 carrier:0           collisions:0 txqueuelen:0           RX bytes:105946 (105.9 KB)  TX bytes:105946 (105.9 KB)

First, ping my interface (notice that I'm using ping6 command):

# ping6 -c 5 2001:470:1f08:16b::2 PING 2001:470:1f08:16b::2(2001:470:1f08:16b::2) 56 data bytes 64 bytes from 2001:470:1f08:16b::2: icmp_seq=1 ttl=64 time=0.033 ms 64 bytes from 2001:470:1f08:16b::2: icmp_seq=2 ttl=64 time=0.048 ms 64 bytes from 2001:470:1f08:16b::2: icmp_seq=3 ttl=64 time=0.062 ms 64 bytes from 2001:470:1f08:16b::2: icmp_seq=4 ttl=64 time=0.047 ms 64 bytes from 2001:470:1f08:16b::2: icmp_seq=5 ttl=64 time=0.032 ms --- 2001:470:1f08:16b::2 ping statistics --- 5 packets transmitted, 5 received, 0% packet loss, time 3996ms rtt min/avg/max/mdev = 0.032/0.044/0.062/0.012 ms

Then, ping the other side of the tunnel (notice the round trip time change):

# ping6 -c 5 2001:470:1f08:16b::1 PING 2001:470:1f08:16b::1(2001:470:1f08:16b::1) 56 data bytes 64 bytes from 2001:470:1f08:16b::1: icmp_seq=1 ttl=64 time=66.7 ms 64 bytes from 2001:470:1f08:16b::1: icmp_seq=2 ttl=64 time=66.5 ms 64 bytes from 2001:470:1f08:16b::1: icmp_seq=3 ttl=64 time=66.5 ms 64 bytes from 2001:470:1f08:16b::1: icmp_seq=4 ttl=64 time=66.3 ms 64 bytes from 2001:470:1f08:16b::1: icmp_seq=5 ttl=64 time=67.4 ms --- 2001:470:1f08:16b::1 ping statistics --- 5 packets transmitted, 5 received, 0% packet loss, time 4007ms rtt min/avg/max/mdev = 66.309/66.720/67.461/0.460 ms

And then, my first IPv6 ping to Google :)

# ping6 -c 5 -n ipv6.google.com PING ipv6.google.com(2a00:1450:400d:803::1013) 56 data bytes 64 bytes from 2a00:1450:400d:803::1013: icmp_seq=1 ttl=57 time=167 ms 64 bytes from 2a00:1450:400d:803::1013: icmp_seq=2 ttl=57 time=176 ms 64 bytes from 2a00:1450:400d:803::1013: icmp_seq=3 ttl=57 time=170 ms 64 bytes from 2a00:1450:400d:803::1013: icmp_seq=4 ttl=57 time=176 ms 64 bytes from 2a00:1450:400d:803::1013: icmp_seq=5 ttl=57 time=176 ms --- ipv6.google.com ping statistics --- 5 packets transmitted, 5 received, 0% packet loss, time 4006ms rtt min/avg/max/mdev = 167.003/173.506/176.744/3.987 ms

And now is time for a browser and what could be better than http://whatismyipv6.com (IPv6 style of course :)

And http://test-ipv6.com

Google redirects me to the UK site although I'm at Spain. That's because among all the tunnels endpoints from Hurricane Electric I've choose the one at London. But there are more. This could become handy later.

 

A curios ping :)

# ping6 -n -c1 www.v6.facebook.com PING www.v6.facebook.com(2620:0:1cfe:face:b00c::3) 56 data bytes 64 bytes from 2620:0:1cfe:face:b00c::3: icmp_seq=1 ttl=51 time=197 ms --- www.v6.facebook.com ping statistics --- 1 packets transmitted, 1 received, 0% packet loss, time 0ms rtt min/avg/max/mdev = 197.501/197.501/197.501/0.000 ms

And a couple more:
