This is a new one on me; a WebmasterWorld regular just drew my attention to it.
Way back when, all of 34 was Halliburton. Eventually the 192-255 segment was sold to AWS. And more recently, when nobody was looking, the 64-127 segment has been sold to Google. That's
34.64.0.0/10
which, if my arithmetic is right, is about 1000 times as many addresses as the /20 they oh-so-efficiently use for crawling.
This is not a new crawl range. Instead it means that some of those unwanted robots from 34 (don't know about the rest of you, but I've never ever met anyone from the 0-63 and 128-191 Halliburton-at-least-this-week sectors) are not AWS, as one might reasonably assume, but Google Cloud and similar.
Whether this makes any practical difference to anyone is a whole nother matter.
