That is a Wikia IP, which is why it has so many (and the others above 100k are all Wikia or internal IPs as well, in addition to most of the rest of that top ten). This method is used to get all wikis an IP has edits on, so we can rename them to a dummy IP when they have been identified as a COPPA user (i.e. we're to remove their IP (anonymise it) when we know they are under 13). This would never apply to a Wikia IP or an internal IP.

This is called in the same way as the method above it for [user activity](https://github.com/Wikia/app/blob/dev/extensions/wikia/UserRenameTool/RenameUserHelper.class.php#L45), which also uses ```WikiFactory::isPublic``` (which uses cached data unless that wiki hasn't had its data loaded in the past 24 hours). This is only called upon a staff member initiating a rename request for the IP address as part of the COPPA cleanup process.
