The dot is a delimiter and can't be part of a hostname.
I was thinking you are wrong.
Period is somewhat permitted in a hostname.
To add to the story, I added a rule to our DNS administration

One aspect of host name syntax is hereby changed: the
restriction on the first character is relaxed to allow either a
letter or a digit. Host software MUST support this more liberal
syntax.

As noted before, RFC 1035 set some specifications. But there were a
