If I were configuring my DHCP server to hand it out to clients, that

It's going by proper standards that a domain name ends with a dot.
That may not be needed, now. But apparently was when I set things up
around 20 years ago, and still works fine that way.
It network configurations, ending with a dot indicates that it *is* the
top of the chain, and nothing else should be appended to it.
Thanks for pointing that out. DNS is very simple in concept and very
complicated in implementation. A lot of people just take for granted
that it works. Mess it up and *nothing* works ;/
As to the dot. DNS is uniform. *Every* domain name, top-level or
otherwise, and every subdomain name, no matter how deep, is followed by
a dot.
Caveat: if a domain description does not end in a dot it is not
considered to be a fully qualified domain name (fqdn).
How utilities such as as nslookup and dig figure out what to do when the
final dot on a fqdn is missing is a mystery to me. Perhaps they always
add a dot then trim the name to have no more than one. IDK
