207.46.13.179 – bingbot/2.0

Recently I’ve been fixing some performance issues due to the behaviour of some web bots. If you are concerned about 207.46.13.179, I’ll let you right away that this a legitimate Bingbot. Here’s an example from the HTTP access log:

207.46.13.179 - - [04/Sep/2019:21:53:15 -0700] "GET /library/file/mustangser532.exe-206653/ HTTP/1.1" 301 4303 "-" "Mozilla/5.0 (compatible; bingbot/2.0; +http://www.bing.com/bingbot.htm)"

207.46.13.179 is requesting content from Freefixer.com approximately every 10 seconds. Quite often, but that’s OK. I would like Freefixer.com to appear at bing.com.

So, how do I know that this in fact is a real Bingbot, and not some unwanted program that scrapes my web site? I’ll use the same procedure as recommended over at Bing Webmasters Tools. That is, a reverse IP lookup on the IP address, and then a forward IP lookup on the results from the reverse lookup. If you end up with the same IP that you started with, and the reverse lookup reports a search.msn.com, you can rest assured that you are dealing with a legitimate bingbot.

207.46.13.179 is the real Bingbot from Microsoft

If you do an ARIN lookup on 207.46.13.179, you’ll see that Microsoft owns the range starting from 207.46.0.0 to 207.46.255.255. So I assume you can expect bingbots from all the IP addresses.
