REVERSE DNS Practices.

hi, I want to ask some folks out there that maintain reverse DNS queries of their respective IP blocks. I want to know if there is a need for me to contact my upstream provider. I am in charge of 2 /24's under LACNIC. I've already registered my DNS servers on LACNIC. but for some weird reason it's not owning reverse resolves. any tips would be gladly appreciated. thanks, b -- () ascii ribbon campaign - against html e-mail /\ www.asciiribbon.org - against proprietary attachments
