.local is a multicast DNS (mDNS) thing. See <https://www.rfc-editor.org/rfc/rfc6762.html> and <https://www.iana.org/assignments/special-use-domain-names/special-use-domain-names.xhtml>. I personally remove mDNS and Bonjour from my machines. mDNS is not the source of truth on my networks. Rather, DNS is the source of truth in my networks, ao I use home.arpa from RFC 8375, <https://www.rfc-editor.org/rfc/rfc8375.html>. Jeff
