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, br...@yoafrica.com wrote: > Slighty related... > > 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 > > On 21 Mar 2009 10:32:30 -0000, John Levine <jo...@iecc.com> wrote: > >> I want to ask some folks out there that maintain reverse DNS queries > >>of their respective IP blocks.
