NEW DOMAIN: dpp.go.ug

[Kevin Darcy]

First of all, why bother with terminating dots? Unlike the blecherous
nslookup, decent DNS troubleshooting tools like "dig" don't implement
"search" algorithms, so terminating dots are usually superfluous.

Secondly, since you're pointing "dig" directly at the ns.imul.com nameserver,
what difference does it make what version of BIND the local nameserver is
running? If anything, this is a difference between the BIND 8 and BIND 9
version of "dig" (possibly related to the newer "dig"s attempt to use EDNS0?).

Having said all of that, however, I just plopped a version of the BIND 9
"dig" on one of our firewalls and I can use it to query this name from the
ns.imul.com server just fine. Are you sure this isn't some sort of local
networking problem? Perhaps an intermittent one?
