The original question asked about an anonymous user changing his IP.

That site calculates ranges from given IP addresses, and has no capability to look up the IP addresses of Wikia users.

If you're dealing with a registered User1 who, after being blocked, repeatedly changes his ip and creates User2-100, then you should report him to VSTF or Staff and let them look up his range and block it.
