I have no idea why you like to have stalls.
My network doesn't have any such things, and there is no reason you have
to stall things to do a lookup.
The above things stall waiting for a lookup to complete and timeout when
they lack a reverse DNS entry.
Lack of a reverse entry DOES NOT CAUSE A STALL. Broken delegations
cause stalls. Unreachable nameservers cause stalls. Not having
a PTR record does not cause a stall as you get back NXDOMAIN.
Fair enough...
If a reverse lookup is slow complain to the administrators of the
reverse zone and if that fails complain to the RIR to get the
delegation removed.
Certainly - I'll let all home users know that this is the appropriate
solution. I'm sure the average customer knows what to do next... ;-(
Whether this is fixed by ensuring proper delegation or by a proxy that
gives the right answer quickly, IMO a reverse DNS local to the homenet
is useful.
