dynamic dns tables, missing "IN"

When last we met... I'd just discovered/realized that in a 10.57.36/22 network you also had to create 3 additional PTR tables for dhcpd to tell named to update. Confirmation and Q&A were greatly appreciated.

This is working fine, was working fine?

Oddly, I'm finding that my current Forward tables is miswritten.

The SOA looks ok, but the records look like this.

Namename  A   ip.number.octet.here
          Txt machine fingerprint

The "IN" Internet record flag is missing, queries to the server are failing.

At this point I might also say that our dynamic IP range is 10.57.36.10 (because we leave a little room at the bottom for routers, etc) to 10.57.39.150, because I left 100 IPs at the very end of the range for static addresses, as not all machines on the network do proper DHCP. For those machines I've manually added some records manually from 10.57.39.250 and counting backwards.

I may have caused my own problems, don't know.

Manually added the "IN" to all of the A and TXT records, but they have disappeared again, breaking nslookup results.

My reverse tables show the same result.

Thank you,
Brian
