One of my sites has been getting queries from googlebot, on the order of:
example-log:220.127.116.11 - - [06/Apr/2016:15:36:56 -0700] "GET /vvytnoxvontwusz.html HTTP/1.1" 404 15136 "-" "Mozilla/5.0 (compatible; Googlebot/2.1; +http://www.google.com/bot.html)" TLSv1.2 AES128-GCM-SHA256
I've gotten a few of these in the past couple of days. The address seems to be authentically in Google's IP space, but I have no clue what's going on, other than that it's properly 404'ing: I was not surprised to find that the referenced page is nowhere on my site, nor elsewhere on the internet (as you'd expect if someone is generating a random string of 15 characters).
I suppose I'm not overly worried about this in the grand scheme of things, but does anybody have a clue what's going on? Thanks!
