I am not a DNS guy. I'm struggling with these instructions and need clarification:
https://docs.opnsense.org/manual/dnsmasq.html#dhcpv4-with-dns-registration
I own my own domain. Instead of lan.internal, shouldn't I use my domain instead? Because, if I setup the way of the instructions, all of my internal clients get the name computer123.lan.internal when they should get the fQDN like computer123.mydomainname.com
This is just a sanity check for me, I'm pretty sure this is what I want.
There is a note in that link to the docs. I think that is what you are missing:
zone, then hosts.
QuoteNote:
.internal is the IANA and ICANN approved TLD (Top Level Domain) for internal use. If you instead own a TLD, e.g., example.com, you could create a zone thats not used on the internet, e.g., lan.internal.example.com.
