VDSL2

At last... an internet connection running at almost the maximum line speed.

Max:   Upstream rate = 26390 Kbps, Downstream rate = 82608 Kbps
Path:  0, Upstream rate = 20000 Kbps, Downstream rate = 79999 Kbps

Speed test: 73.31Mb/s down, 15.21Mb/s up, 30ms ping Ping test: 28ms 1ms

Move Over IPv4 (Bring on IPv6)

Move Over IPv4 (Bring on IPv6)

Over 300 people from the UK Internet community got together to mark the end of IPv4 at the London Transport Museum and promote the adoption of IPv6.

Ed Vaizey MP did an introductory speech followed by an review of IPv4 by Prof Peter Kirstein (UCL) and IPv6 by Simon McCalla (Nominet). After a short panel debate on IPv6 readiness there was a mock handover of 185/8 from IANA to RIPE NCC. Finally, Gary Feldman performed his RIPE55 song "The day the routers died" (a parody of American Pie).

I took a few photos and some video. The Internet survived unharmed (although I did turn it off at one point, sorry if you were using it at the time).

Enumerating ip6.arpa

Based on an idea from a NANOG post I created a script to walk an ip6.arpa zone and list all IPv6 hosts.

It works surprisingly well:

More details and a method of preventing this are in my ip6walk git repository.

Finally. It took an extra 17 days to work around BT's inadequate ordering system, and then another extra 10 days for BT to send out an engineer before they could discover that they needed to override their Dynamic Line (mis-)Management system in order to allow the upstream line rate to be 10000Kbps... for a few more hours. Followed by another 3 days for it to slowly automatically increase the speed because they're incompetent and unable to override the system. Additional delay provided by AAISP caching the line check result too aggressively.

Internet connection

Since wednesday (the 22nd) I've been able to use my ADSL connection, so I now have IPv4, (native) IPv6 and multicast IPv4 at the fastest possible speeds. :)

Now if only I had a username and password to connect with, and account details of where to send money...

Dalgety Bay

After moving into a flat in Dalgety Bay on Saturday, I'm now waiting for a proper internet connection. The speed of dialup is really annoying me. It takes BT 14 hours to reconnect a phone line but 3 days to notice it exists and a further 7 days to activate ADSL on it...
