in-addr.arpa delegation, or lack thereof

The problem of the day is in-addr.arpa delegation. We’ve been migrating some of our older servers to IP addresses in a new C block that was recently assigned to us by Verio. We’ve been having all sorts of unexplained lookup problems with those servers and finally discovered the cause today. Verio never properly delegated the authority to our DNS server for the new C block. It took a full day of debugging and playing with nslookup and, of course, turned out to be something obvious and simple (doesn’t it always?). Verio submitted the delegation update to Arin tonight. Now I’m a full day behind on my schedule for this week but at least I can get back to more interesting work now.
