You aren't missing anything. What I am trying to accomplish is a political
work-around, really. We have a partner company that uses split DNS and
provided us with an address for a DNS proxy we could use to resolve their
hostnames. However, sometimes the resolutions the proxy provides are
incorrect for my network and I have to poison my DNS server by getting the
correct IP from the Internet and becoming authoritative for that particular
host. This works well until they change the IP Address. I am using
PowerDNS to dynamically poison my BIND DNS server by checking the hostname
my users are trying to resolve, compare it to the list of hostnames I know
the DNS proxy won't resolve correctly, and then either get the info from the
partner or from the Internet. :-/ It's just easier for me to craft a
technical solution than to try to get this partner to change its evil ways.
