Starting Nov 12 / 2017, my website's landing page (default.html) has been requested 32 times from 18.104.22.168. The IP belongs to Cisco Systems Ironport Division. Half of these hits happen anywhere from 7 to 40 days apart from each other, a couple happen with a spacing of 60 and 140 days, and the rest happen between 0 to 6 days apart (4 hits on one day, and a couple other days where there was 2 hits on same day). I'm posting about this because I noticed some of those hits last week and decided to get a full historical picture of them.
Five of these hits have had this user-agent:
Mozilla/5.0 (Macintosh; Intel Mac OS X 10_12_6) AppleWebKit/537.36 (KHTML like Gecko) Chrome/64.0.3282.167 Safari/537.36
All others were this:
Mozilla/5.0 (Windows NT 10.0; WOW64; rv 53.0) Gecko/20100101 Firefox/53.0
No other files (ie favicon.ico or robots.txt) were requested.
Any theories as to what this Iron-port bot (or proxy?) is doing or what it's purpose is?
