I keep getting image requests from 70.37.130.8 with a blank user agent.


I can't block blank UAs because of some of the services that we use dont send the UA info... go figure..

Anyhow, it appears to be from
NetName: MICROSOFT-DYNAMIC-HOSTING

but is that really Bing/Microsoft or what?

Sure you may.
Just used multiple condition focused upon both the UA & IP.


There's an old thread around on MS Dynamic Hosting [webmasterworld.com]

# deny blank UA; IP ONLY
RewriteCond %{HTTP_USER_AGENT} ^-?$
RewriteCond %{REMOTE_ADDR} ^70\.37\.([0-9]|[1-9][0-9]|1[0-8][0-9]|19[01])\.
RewriteRule .* - [F]

FWIW, it's my understanding if your server has installed the latest version of Apache (2.4-?) that you may use CIDR.

My el-cheapo still has 2.2 installed.

And not intending to hi-jack this thread, however I had some email correspondence via a website inquiry and the email header contained the following:

65.54.190.zzz
Microsoft Hosting

Anybody have a clue if MS has a similar hosting range in the 52-55 Class B?

I'd tried blocking some of these hosting ranges of theirs only to find that bing shopping was pulling their images from that range.... pisses me off that they aren't supplying a user agent.

I've blocked blank UA for close to 10 years:

RewriteCond %{HTTP_USER_AGENT} ^-?$
RewriteCond %{REQUEST_METHOD} !^HEAD$
RewriteRule !^(favicon\.ico|403\.html|w3c/p3p\.xml|w3c/policy1\.xml|robots\.txt)$ - [F]


But allow HEAD requests for the above files.

As have I and many others (standard practice even at the suggestion of SE's and confirmation of DNS), however apparently his situation is unique.

You can verify IPs at bing dot com/toolbox/verify-bingbot
Not the most useful way to do things.
