The investigations that produced the ball of string to the right began when I noticed that some IPs seemed to quickly shift while users were using them, and I collected examples where I could find them.My list of IPs was incomplete, as is clear from the list below, which lists the IPs together with their unique host-name, which fall into two clear series, which start in red.
Clearly, the first series of number should have begun at 66.185.84.68 (= wc01.mtnk.rnc.net.cable.rogers.com).This, however, ignores the more important question: what does "wc" stand for? "Water closet"? "Winston Churchill"? "Workers' Compensation"?
No. It's quite simple. It clear stands for "web cache", which is what these IPs do.
