Is it possible to merge edits from an IP to a user account in Wikipedia?

I'm guessing there might be some 'owner' issues, but if one could prove no-one else used the IP apart from 'guest' posts and logged in user posts, could the edits be merged to a named user?

Username (and also IP) merging is technically possible but isn't done. It would require a highly manual effort by database admins. And yes it is hard to proof that this were your edits (how should they know if it was you?).

Yeah, I thought as much. It just looks a bit suss when you have orphan edits on a work IP when you forgot to log in <_< – glasnt Jul 8 '10 at 5:00

It is in fact possible for bureaucrats to merge user accounts in MediaWiki wikis, without manually editing the database, using the User Merge and Delete feature. However, this extension is disabled on the English Wikipedia. It is enabled on Wikivoyage for purposes of migrating user accounts from the old Wikivoyage/Wikitravel. There is a (partial) list of wikis that have the feature enabled.

I'm not sure whether the tool lets you merge anonymous (IP) accounts. I didn't see any such merges in the logs of a few wikis from the list, but that doesn't mean it's impossible.

No, it is not possible to merge edits from IPs and user accounts together. There are actually two different things inside the MediaWiki database – Hydra May 1 '13 at 12:33
