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.
