the 20th or 21st century answer? if you really don't care about the actual node, then you should map the numbers to topologically significant names - after all, the reverse map follows topology, not some goofball - layer 9 - ego trip thing. or - the more modern approach is to let the node (w/ proper authorization) do a secure dynamic update of the revserse map - so the forward and reverse delegations match. ... a -VERY- useful technique. --bill On Sat, Mar 21, 2009 at 01:38:55PM +0300, bruce@yoafrica.com wrote:

Can people please post their recommended reverse dns naming conventions for a small ISP with growth and scalability in mind. I already have one drawn up, but I would like to contrast and compare :D
Thanks

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.
The RIRs don't maintain rDNS for you. You'll have to trace the delegations downward from in-addr.arpa, find out who's handling your /24's, and contact them to get them to delegate your chunks to you.
