Looking for a pointer on getting reverse mapping with DDNS to work with DHCPD & Named.

Hi Jim,
No, sorry, wrong IP address, the real IP address of the dns server, not
the client.
zone dhcp.coloradostudios.com <http://dhcp.coloradostudios.com>. {
primary your_dns_server_IP_address; <----- change from 127.0.0.1
key DHCP_UPDATER;
}
Also do you have a /var/log/named.log file or debug log file for named,
other than messages, might have more information.
Can try nsupdate with debug to see if this gives any clue also.
nsupdate -d
> server your_dns_server_here
> key your_key_here
> update add 101.20.10.172.in-addr.arpa. 3600 in ptr
dhcp-172-10-20-101.coloradostudios.com
<http://dhcp-172-10-20-101.coloradostudios.com>.
> do extra CR to get it to go
should see lots of debug information here

man nsupdate
best!
