Lucy - thanks for the correction.
It is, in fact, 172.217/16
Telus was the one I was actually registering in my system, G was the accidental finding when I checked to see how big telus was. I always try to check adjacent IP ranges when registering a naughty one.
Don't know about WMT authentication but to verify ownership of a domain (aka web URL) you have two options: one is a file in the root, the other is to paste the verification code into each page header - the one I preferred until I gave up playing G's games. Same methods for bing and (once upon a time) yahoo. The codes are much longer and more alpha-numeric than G's current attacks on web sites.
