ronbaby Posted July 30, 2013 Share Posted July 30, 2013 I suppose that this might perhaps be an FAQ, but I haven't been able to find the answer in any of the Spamcop FAQ files I've looked in, so I'll just ask. I would like to check to see if there are any single IPv4 addresses within a given range that are currently listed on the Spamcop blocklist. What is the proper way to do this? Note that I am _not_ either the owner or the administrator of the IP address range in question, but I still do want to get the information for analysis. (No, I am not a spammer. I am an anti- who is trying to do research on certain blocks that I feel are exceptionally "dirty".) Obviously, I could just write a trivial little scri_pt that would generate each of the IP addresses in the range in turn and then I could also write another trivial little scri_pt that would check each one of those individual IP addresses, in turn, against bl.spamcop.net, but that does seem rather horribly inefficient, and if the block is big... say like fer instance a /16 or something like that... then I feel that I would be needlessly taxing Spamcop's DNS resources if I did it this way (which would involve making 65536 separate individual DNS lookups against bl.spamcop.net). So basically, is there a proper, recommended, and _polite_ way of checking an entire block against the blacklist, I mean, ya know, even if the party who wants the info is not the owner of the block in question? Also and separately I'd like to know what additional information Spamcop provides to the general public about individual entries in/on the Spamcop blacklist. Specifically, if I have an address, A.B.C.D and I have checked and seen that it is in fact currently listed on the Spamcop BL, then what information about the causes for that listing can I, an interested third party, get from Spamcop about those causes? Can I see the spam message that caused or or maybe even a redacted version thereof? If so, where and how would I find that? Link to comment Share on other sites More sharing options...
