That's a great list - thank you for sharing.

Thought I'd add the IP assignments per country for those new to access control that don't know about these:
Anyone got anything else good, anyone?

The MS lists are (mostly) very short ranges! A real pain to add to blocklists. Probably worth doing, though, if they are clouds.
The v=spf returns are for mail (part of DKIM encoding/checking) - they specify IPs that can send mail so are probably not a threat to web servers.
Looking more closely at the MS ranges: some can be concatenated; others I already have listed as bot IPs. Does that mean they are changing usage?

From what I read the Google SPF lists are pretty all encompassing because the change IPs for stuff all the time and that's pretty much the list I had too. Says right on their website that it's where to get the definitive list of IPs and that comment was in the Google Developer section I think and wasn't an email discussion.
MS IP usage is all over the map so who knows. I think any IP is fair game at MS to be used for anything.
I just want sources that I can download and process automatically and keep updated without going stale and these look good so far but you're right, the MS list needs some concatenation.

It figures that G would abuse the spf system. :(
I've been wanting to ban G mail for a long time but my customers and their customers still insist on using it.
A while ago I began blocking all "bot company" IP ranges except for known bot IPs. This seems to block some "mobile" proxies but since Y and G seem to use these IPs indiscriminately, tough.

From the Azure XML file:
Now I see "msnbot-media/1.1 (+http://search.msn.com/msnbot.htm)" coming from 188.8.131.52 <=> msnbot-65-55-211-186.search.msn.com. This Azure IP list is garbage.

I started using BGP Toolkit from Hurricane Electric site for finding IP Ranges that belong to specific organization/colo/datacenters a while back. These are on more granular level. Seems to work OK.
Goog IPs for example: bgp.he.net/search?search[search]=google .
The RIR lists from FTP Sites that incrediBILL mentioned are also pulled on monthly bases and processed into a DB. Also have a subscription for ip2location DB.

Interesting stuff for sure. I use ip2location as well, but maxmind has a really great one as well that I use on an ad need basis. You can look up 25 per hour free on their site.
