Seeing lots of ips in proxied sites report

Need to do a reverse DNS lookup for these so that we get more useful reporting.

Ignorant question: I suppose the system will cache these to some extent? If not, a small cache for the most used ones would probably help.

[oxtoacart]

@aranhoide Good point. I'll put in a little LRU cache.

Hmm, I'm not sure this is going to be very useful. Example of resolution / reverse lookup:

www.google.com -> 74.125.198.147 -> og-in-f147.1e100.net
