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.
Agreed - and its certainly manageable if you automate the process. Generating reverse lookups from your config backups is a pretty reliable way of doing this for infrastructure/dynamic allocations. Your NOC staff will love it because they won't have to worry when they shuffle around local pools, or turn up new interfaces.
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.
