What Bingbot does
Bingbot crawls pages automatically for the Bing search index, with desktop and mobile user agents. Its rendering engine is regularly updated to the latest stable Microsoft Edge, which is reflected in the Chrome/W.X.Y.Z part of the user agent. It honors robots.txt and the Crawl-delay directive.

07 · Verification
Is it really Bingbot?
Anyone can copy a user agent. Real Bingbot requests come from the IP ranges published at bing.com/toolbox/bingbot.json. A reverse DNS lookup of a real request resolves to search.msn.com, and that hostname resolves back to the same IP.
