Dear janes as I know many services use reverse lookup as a sender authentication technique. e.g. Email server using this technique to reduce spams.( if the ip adress of sending smtp server has no reverse lookup it's messages will be considered spam). regards,
Date: Tue, 20 Apr 2010 16:08:04 -0400 Subject: Reverse DNS Question From: jamesmartin () ieee org To: nanog () nanog org All: In the process of requesting a block of IP's for a client, ARIN requested that we list Reverse DNS Servers for the block. I've never done this before, nor have I ever thought it through. What is the purpose for this besides resolving name-based reverse lookups? Are there any definitive guides out there on how this works (besides the ARIN site)? I know this is really basic stuff but I don't know it and have never needed to know it until now.
