I'm glad I wasn't the only one who felt that line was insufficiently descriptive.

I had recently seen the problem, so I was able to guess what it meant, but I don't see any reason to be vague about it, especially since multiple tech update blogs in the past have plainly said "127.0.0.1":
 * User_blog:DaNASCAT/Technical_Update:_July_15,_2014
 * User_blog:Kirkburn/Technical_Update:_March_3,_2015

The line is also additionally misleading as it says "displayed in the Recent Changes list for a brand new wikia", but the main page move is not simply displayed as being 127.0.0.1 in the Recent Changes list, it's attributed to 127.0.0.1 in all the usual place such as page history, Special:Contributions, Special:Log

I still think saying "An incorrect IP" is needlessly vague. Perhaps in return, I should start making vague bug reports.
