I use Novell's DynamicDNS feature. the problem is that Resource records
get in but they don't get cleaned out after the record is no longer valid
(records remaan in the dns zone after there is no longer a corresponding
IP addr.)

I seem to remember using a named.nlm option that cleared out these null
resource records. I'll be darned if I can remember what the option is or
where I found it. Can ya help a brutha out?
