Via a comment at Strange Maps [1], I came across this neat IPv4 (Internet Protocol version 4) Map [2] (which is based off this xkcd IPv4 map [3]). What's neat is that this map shows you the ownership of IP (Internet Protocol) blocks. It also allows you to zoom in to see the finer detail of ownership (for instance, Level 3 Communications [4] owns 3.0.0.0/8, but has leased out 4.3.0.0/16 to Verizon [5]).
I think Smirk will like this.
