Nathan called it a sub-domain (and you agreed)...

It's not a sub-domain it's a host. Only hosts can have IP addresses.

Charles, you appear to be talking about setting up "A" records (aka DNS
host records) which I would call mapping sub-domain names to IP addresses.

For a definition of sub-domains see:

http://en.wikipedia.org/wiki/Subdomain

I began learning about sub-domain names after having to pay what appeared
to me to be an outrageous premium for a wildcard certificate for *.
my-domain.com, where the asterisk refers to "all" sub-domains of a
registered domain.

Charles is correct, and in fact that Wikipedia article agrees. To
quote:

|A resource record, such a A(host), CNAME(alias) or MX (mail), should

|specific data).
