I have a bunch of these in my nginx log file, on a range of URLs:
on 220.127.116.11 - - [12/Nov/2015:10:40:25 +0000] "GET /myadminfolder/page.html HTTP/1.1" 200 1247 1800 "-" "Google favicon" "18.104.22.168"
Where 22.214.171.124 is my home IP address.
(Whatever it is isn't logged in so thankfully it gets bounced to the login page after this.)
I don't fully understand these, what they are or why they happen. I looked the IP address up and it does appear to be google (http://www.dnsstuff.com/tools#ipInformation|type=ipv4&&value=126.96.36.199).
My admin folder is "secret" and not linked anywhere (security through obscurity...). That and my IP address suggest it must be something to do with my Chrome browser, I guess?
I've not accessed that page myself since 22 hours prior to this log though, so it's certainly not something that happens AS I browse.
Can someone tell me
- what this is
- WHY it is
- if I should be worried about it!?
