When you query against bl.spamcop.net, you take the connecting server's IP address, reverse it, and query for that record. If it answers 127.0.0.2 it's listed, if it errors out, it's not.
i.e. 1.2.3.4 connects, your server queries DNS for 4.3.2.1.bl.spamcop.net. 127.0.0.2 It's never necessary to simply query for bl.spamcop.net itself. nslookup -q=ns bl.spamcop.net gives: Non-authoritative answer: bl.spamcop.net nameserver = blns4.spamcop.net bl.spamcop.net nameserver = blns11.spamcop.net bl.spamcop.net nameserver = blns6.spamcop.net bl.spamcop.net nameserver = blns8.spamcop.net bl.spamcop.net nameserver = blns5.spamcop.net bl.spamcop.net nameserver = blns9.spamcop.net bl.spamcop.net nameserver = blns10.spamcop.net blns4.spamcop.net internet address = 194.109.6.147 blns11.spamcop.net internet address = 209.92.188.201 blns6.spamcop.net internet address = 209.198.142.146 blns8.spamcop.net internet address = 66.6.205.130 blns5.spamcop.net internet address = 198.145.240.35 blns9.spamcop.net internet address = 208.39.222.166 blns10.spamcop.net internet address = 206.67.234.226 ------------------------------------------------------- This SF.Net email sponsored by: ApacheCon 2003, 16-19 November in Las Vegas.
