Re: [Declude.JunkMail] OT - RevDNS lookups by range

Well, I do like the name. I'll give it a shot. Finding the ranges in dnsstuff.com is too much of a chore. ----- Original Message ----- From: Matt To: [EMAIL PROTECTED] Sent: Wednesday, December 08, 2004 2:18 PM Subject: Re: [Declude.JunkMail] OT - RevDNS lookups by range Scott, I've been using a tool called Angry IP Scanner.  It sometimes dies on bad data being returned, but otherwise it is a good tool for querrying large blocks of IP's for reverse DNS entries.  I would strongly suggest that you turn off the port detection since it really doesn't give reliable results (based on how the servers are configured). Matt Scott Fisher wrote: I like to research a range of Reverse DNS entries before potentially blocking a IP range.   I'm looking tool (an online one would be fantastic) where I could type in a range say 209.200.18.0 (today's culprit) and it would provide a list of Reverse DNS entries for 209.200.18.0 through 209.200.18.255. This would be a time saver in creating my own IP blacklists.   Any suggestions?         -- ===================================================== MailPure custom filters for Declude JunkMail Pro. http://www.mailpure.com/software/ =====================================================
