Adding IPv4 hostnames using the DNS Forwarder catches A record requests to the host's FQDN but not AAAA record requests
0%
Description
I have an IPv4-only VLAN that is adding hostnames to DNS using the features available under the DNS Forwarder tab.
I have a domain, netham45.org, that has a wildcard pointing to Cloudflare for IPv4 and IPv6 on the public internet. Within my local network hosts should be overridden, so that <host>.netham45.org points to the internal IP. This works for A records, but I am still getting AAAA records returned from CloudFlare.
Example:
nslookup homeassistant
Server: UnKnown
Address: 192.168.3.3
Name: homeassistant.netham45.org
Addresses: 2606:4700:3037::6815:291e < Cloudflare provided AAAA record
2606:4700:3036::ac43:9f7e < Cloudflare provided AAAA record
192.168.3.144 < pfSense provided A record
I imagine there's a few ways to fix this but the one that makes the most sense to me is if pfSense knows of an A record provided by DHCP it should not provide an AAAA record from upstream.

- Status changed from New to Not a Bug
That is not a bug, it's a configurable behavior. It depends on the value of the system domain local zone type.
