Severity: 3-Major
Zone Runner entries cannot be modified if an IPv6 DNS name server is listed first. This can happen when a user runs the tmsh command tmsh modify sys dns name-servers add { <IPv6> } as the first dns name-server. This will show in the /etc/resolv.conf file (an example) nameserver 2001::1 nameserver 192.168.100.1
ZoneRunner records cannot be modified.
When an IPv6 nameserver is the first server defined.
Do not use DNS server with IPv6 address or add IPv4 server at top of the list.
The IP address type was not set properly while communicating with BIND. This does not matter if the first nameserver listed is an IPv4 address or if there are no nameservers listed at all. If the first nameserver listed is an IPv6 and the IP address type is not set to IPv4 (AF_INET), BIND libraries will attempt to use the IPv6 library from /etc/resolv.conf. We not properly set the AF_INET type to IPv4.
