Hi, I'd like to request an enhancement: it should be impossible to register a username that is also a valid IP address. The reason is that this leads to confusion with pages such as Special:Contributions etc. and is thus used by some sneakier vandals to make tracking them more difficult (compare [[en:WP:VIP]]). Thanks!
This was added long, long ago. If it's stopped working, can you please give some specific examples? I'm not able to replicate the problem.
There's http://en.wikipedia.org/wiki/Wikipedia:Vandalism_in_progress#User:192.197.71.189 which mentioned this issue.
There was a regression caused by changes to the checks in the IPv6 support. It should be fixed now, and I've deleted the 50 accounts on en.wikipedia.org that were created.
Thanks. ^_^
