Need /24 (arin) asap

A couple of suggestions on "cleanliness" checking:

-Here's a link to a quick-n-dirty Python script I made to check against a bunch of DNS blacklists:

-We once got caught after buying a "clean" block that was (unknowingly to us) on an old un-maintained blocklist called iblocklist. You can search that list here: They didn't respond to any contact attempts, and yet a number of carriers and hosts out there use those blocklists. In the end we had to re-purpose that block for internal use only and re-number a few customers.

Hi Bryan and all,

Could you please recommend few places or vendors to check on cleanliness?

We've had good results working with Addrex.

I would still strongly recommend you do your due diligence for "cleanliness".
