Prevent DDNS updates on DNS server for specified zones/names.   Not sure
what nameserver you're using but BIND can be configured to prevent DDNS
updates at individual name level if needed.

I'm using BIND 9 on CentOS 7.

This already happens for the reverse zone as a result of my zone declarations in kea-dhcp-ddns.conf:

"forward-ddns" : { "ddns-domains" : [ { "name" : "dhcp.lsi.lan.", "dns-servers" : [ { "ip-address" : "127.0.0.1" } ] } ] }, "reverse-ddns" : { "ddns-domains" : [ { "name" : "6.96.10.in-addr.arpa.", "dns-servers" : [ { "ip-address" : "127.0.0.1" } ] } ] },

The main problem is that the log fills with update errors because the reservation IPs aren't in an updatable zone (ie. they're in 96.10.in-addr.arpa.). I want the log to only show real errors so I can find the real problems.
