DubBot crawls websites to conduct its testing via the use of a headless browser. If you use Google Analytics, it will pick up on these visits, and will report them back you. The visits are reported similar to the way that normal users are reported. (It will currently report the visits coming from Boardman, Oregon, which is where our Amazon's AWS service is hosted).
Google provides instructions on filtering these visits.
The crawler's IP address is: 184.108.40.206
Note that this IP address is subject to change. The DubBot team will contact clients in the rare event of a change.
