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.
Are there any network operators actually doing this on a large scale?
