Do you "own" the target host? Can you issue your own SSL/TLS server
certificate?

Because you can issue a certificate for an IP address as well as for a name
(or for both one or two names and one or two addresses). Cute feature: with
a name, you can wildcard the high order node, e.g., *.foo.com. With an IP
address, you can wildcard the low order byte, e.g., 192.168.1.*

No, it's an SSL (TLS) connection. Need to address by hostname.
