Caught this in the logs the other day:

Started GET "/verify-UncategorisedWebsite?aHR0cHM6Ly93d3=" for 198.240.130.75 at 2012-12-03 14:51:50 +0000

I bumped around a bit and couldn't find anything that should be searching for that. Is this a webcrawler? If so, anyone know who?

It gives you the ip address. How are we suppose to know who owns it? –  Ramhound Dec 3 '12 at 16:07

Apart from doing the usual reverse dns and a whois lookups, you're left with the option to phone these people and ask them what they want from you.
