For whatever reason, going to those IP addresses, take you to 2 these pages:
[3] http://bitbucket.org/dqvsra [4] http://bitbucket.org/antonrylov
There isn't anything really of interest on either of the pages. It's not like you're seeing their logged in page. This is just some kind of routing issue with Bitbuckets server configuration.
