Welcome to WebmasterWorld Guest from 220.127.116.11
Unfortunately I can't block the service. One of my clients gets traffic from USA and I'm not entirely sure which ISPs without a major investigation, but I suspect some are from comcast.
this is the "business" IP range; typically for company web sites and services - no different than any other server farm IMO.

If the IP Address was also 18.104.22.168 to 78, then you have come to the right place to find out about who was probably crawling your site. If it was a different IP address then someone else is hijacking my crawler's name.
As my bot page explains...
...if you disallow my robot in the robots.txt file it won't crawl your site beyond grabbing the robot page.
