As admin you can disable anon editing in the wiki features. At least for now you should do that to stop the IP. If you don't know where, you can do it on Special:WikiFeatures.

Another important note: Do not react to messages or something from the IP. Just block the IP and remove the messages and rollback the edits on the wiki pages.
