MsnBot failing DNS lookup

IP address is registered to Microsoft Corp

[Vimes]

Hi,

finally we've managed to set up a reverse forward look up on our server,

I've had many visit from this ip range 65.55.234.* which fails on the first hurdle which is to match the DNS this is what i'm getting:

Resolve Host: bl1sch2042001.phx.gbl

so is this a legit Bot and if so is any one else seeing this is from MSN ip range.

65.52.0.0 - 65.55.255.255

They give us a formula and then change the goal posts ;)

They're running rogue bots that emulate browsers (aka user agent spoofing), and that don't honor robots.txt or <meta name="robots" content="noindex,nofollow">.

Ostensibly, the purpose is to detect cloaking, but that bot of theirs doesn't have proper etiquette or good manners.

This thread might be of interest:
