@WeirdAlex03 @arichtman .local is for link local multicast DNS (aka zeroconf or Bonjour).

It's generally a bad idea to provide a .local zone via unicast DNS, since it'll cause most systems to disable multicast DNS.

I've been using .local for internal DNS since before mDNS was a thing.
Apparently I didn't get the memo that I should no longer do that. 🤦‍♂️

@wdormann @WeirdAlex03 @arichtman Yep. If you forced mDNS on for a particular system, it likely wouldn't ever query any of your unicast .local names.

Things likely worked for you because most systems these days will query the SOA record for "local." via unicast: if they get a hit, they disable mDNS.
