I have no comment on mdns4_minimal because I don't really know what that
is.
AIUI mdns4_minimal is for devices that configure themselves using
multicast DNS on .local. If you put dns first, then the names of any
.local devices will be leaked out of your LAN and on to the Internet's
DNS servers. [NOTFOUND=return] is what prevent that happening IF you
leave the order alone.
(BTW don't use .local for your LAN domain name.)
Why is that? (recently I was starting to believe I should stop using the domain
names I had chosen, and start using (what I thought was) the standard of .local)
Is it your personal preference, or a technical necessity?
What is best practice for a local LAN prefix? (I have never found conclusive
instruction).
Frankly, neither have T that actually makes sense. Particularly as
future proof. The smartest dog I ever met was not a dog, but a tamed
coyote. This was in the '70's of the last century. So when I setup my
home network and built my first linux box in 1998, this machine became
coyote.den as the domainename. Its arbitrary and has not yet clashed
with anything the powers that be have defined. My network lookups are to
look first at /etc//hosts, and failing to find it, my ISP's dns. I
suppose eventually they'll issue .den and I be forced to pick some other
3 letter name for my local domain. Until then, I am as that now very old
saying goes, FAT, DUMB and HAPPY... And my machines, all of them, can
tour this planet transparently.
It is my belief that .local is a MS idea originating from the configuration of
their servers. Is this correct?
.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>.
Neither of these 2 documents appear to infringe on what I am doing at
this time. OTOH, I am not famous for thinking inside the box. This
advise, if followed and something gets broken, you get to keep all the
pieces. It has worked for me for 26 years.
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>.
