prabhjot Posted August 15, 2014 Share Posted August 15, 2014 Hello all, I am new to SpamCop. I read on this page http://www.spamcop.net/fom-serve/cache/351.html that we can use a dns query to know if an IP is in a black list or not in our custom application/software. The page says that if I want to check an IP like 1.2.3.4 then my dns query should be: nslookup 4.3.2.1.bl.spamcop.net But for me this returns the messsage that this is a non-existent domain. I wanted to confirm my understanding. So, if I receive non-existent domain message it means that IP is not blacklisted else it is blacklisted? Thanks and have a nice day!

Farelf Posted August 15, 2014 Share Posted August 15, 2014 And yes, if using the DNS query "Non-existant domain" means unlisted, 127.0.0.2 means listed, like in Non-authoritative answer: Name: 226.212.189.177.bl.spamcop.net Address: 127.0.0.2 (for IP address 177.189.212.226) Oh, and the text value Non-authoritative answer: 226.212.189.177.bl.spamcop.net text = "Blocked - see http://www.spamcop.net/bl.shtml?177.189.212.226" Link to comment Share on other sites More sharing options...
