Description
The link circled below (related to why it's best not to use .local for your system domain) points to a 15-year-old mailinglist page which is no longer available (404)
https://www.unbound.net/pipermail/unbound-users/2011-March/001735.html
I believe a better page to link to would be RFC 6762, Appendix G, which explains it well:
Using ".local" as a private top-level domain conflicts with Multicast DNS and may cause problems for users. Clients can be configured to send both Multicast and Unicast DNS queries in parallel for these names, and this does allow names to be looked up both ways, but this results in additional network traffic and additional delays in name resolution, as well as potentially creating user confusion when it is not clear whether any given result was received via link-local multicast from a peer on the same link, or from the configured unicast name server. Because of this, we recommend against using ".local" as a private Unicast DNS top-level domain.
This is current as of pfSense 25.11-RELEASE

Actually, perhaps a slightly better link would be: https://datatracker.ietf.org/doc/html/rfc6762#appendix-G

Thanks for the report.
I can confirm this on
25.11-RELEASE (amd64) built on Mon Dec 15 12:04:00 EST 2025 FreeBSD 16.0-CURRENT
and agree that https://datatracker.ietf.org/doc/html/rfc6762#appendix-G is a good replacement.
