And, of possibly more importance to more people, is when people start
claiming bogus authority for the reverse of a /8. For example, last week
someone was claiming authority for 205.in-addr.arpa and 204.in-addr.arpa
instead of for their appropriate /24s. A good quarter of the servers I
checked had at least one of these bogus records, rendering reverse lookups
for 204 and/or 205 non-functional and messing up anything that relys on
reverse DNS working.
I think this is a big deal when it happens, especially for the people
using the address space it affects. Am I overreacting?
If the server admin is unreachable, I think the provider should attempt
contact and, if necessary, perhaps even filter the server. Most providers
seem to have a "oh, that's bad. We'll get to it in a day or two"
attitude. I tend to consider it a serious operational problem that needs
to be fixed ASAP.
