Bing's verify page says some of these are NOT verified Bingbot IP addresses. If you follow the URL in the UA you end up with Bing's verify tool. It does not have any equivalent tool for the msnbot but by the same token they do admit to 65.52.109.114 while disavowing 131.253.26.233, 131.253.36.194, 131.253.26.242 and 131.253.24.128 with:

Verdict for IP address 131.253.26.233: No - this IP address is NOT a verified Bingbot IP address.

I did not check all the IPs listed, their captcha stinks and I can't sign in on FF due to their stupid geo-language fixation. I know it shows up as Microsoft's range, but they are telling people that it is not them. ?.
