`adidxbot`

Bing says AdIdxBot is the crawler used by Bing Ads. It crawls ads and follows the websites from those ads for quality control, with desktop and mobile variants. The row title is AdIdxBot. The published strings contain adidxbot/2.0. The help URL HTML is an application shell. The article was read from the help API that page loads, ArticleId 8c184ec0. The page says robots.txt files can be configured to tell Bing crawlers how to interact with the site. It does not say that this crawler obeys every directive. This check matches the whole token and still reports the RFC 9309 decision.

robots.txt token: adidxbot
Operator: Microsoft
Kind: ads_check
robots.txt: tells_how_to_interact. The vendor says a robots.txt file can be configured to tell this crawler how to interact with the site. The cited page does not say that the crawler obeys every directive.
HTTP user-agent: Mozilla/5.0 (compatible; adidxbot/2.0; +http://www.bing.com/bingbot.htm) The row title is AdIdxBot. The page also prints an iPhone string and a Windows Phone string, both containing adidxbot/2.0 and +http://www.bing.com/bingbot.htm. The iPhone string is Mozilla/5.0 (iPhone; CPU iPhone OS 7_0 like Mac OS X) AppleWebKit/537.51.1 (KHTML, like Gecko) Version/7.0 Mobile/11A465 Safari/9537.53 (compatible; adidxbot/2.0; +http://www.bing.com/bingbot.htm). The Windows Phone string names Lumia 530. The page does not print a separate robots.txt User-agent line.
IP list: None on the cited page. The page says user-agent strings are easy to spoof, so a matching string does not prove the request is from Bing. It links to the Verify Bingbot tool and to the verification-methods article. This article does not publish an IP list. Botcard does not call that tool and does not copy addresses.
