Running BIND 9.10.3-P4-RedHat-9.10.3-12.P4.fc23 and DHCP Server 4.3.3-P1. DNS Zones report no errors and appear to work (dig, nslookup, nsupdate, dnssec, rpz, etc.). DHCP starts up without complaint, assigns ip, but log file messages similar to: "Unable to add forward map from pc2.blkdiamonds.lan. to 10.0.2.63" appears for each client.
I've read man pages, forum posts, dhcp-users lists and archives but I haven't been able to determine what's different in my configuration that causes the DHCP server to send the client's forward map back to the client?
Any ideas will greatly be appreciated.
