Description

It looks like filter DNS is choking on the IPv6 entries.
To test I created a network alias containing:
2607:f8b0:4000::/36
2a00:1450:4000::/36
chaos.pfmechanics.com
forum.pfsense.org

The /36 subnets are not added to the table.
I tested in 2.2.6 and 2.3. Problem appears identically.

The resolver log shows:
Feb 10 13:10:56 filterdns invalid netmask '/36' for hostname 2607:f8b0:4000::/36
Feb 10 13:10:56 filterdns invalid netmask '/36' for hostname 2a00:1450:4000::/36
Feb 10 13:10:56 filterdns failed to resolve host chaos.pfmechanics.com will retry later again.
Feb 10 13:10:57 filterdns adding entry 208.123.73.18 to table Test_V6subnet_with_hosts on host forum.pfsense.org
