Hi Brian,
to be more generic in the answer, you can map as many FQDN (fully qualified domain name) as you want to a single IP via DNS (you can even enable wildcard records in certain DNS server software that will match *.yourdomain.com to a default IP).
That tells {client_software} that {this_FQDN} is {this_IP}. {client_software}will use that information in whatever form is suitable to {client_software} - in most cases it will contact {server_sofware} running in a server (or group of servers) running as {this_IP}. It is up to {server_software} to determine how the request from {client_software} is handled.
For a variety of {server_software}, there is support for named based virtual hosts, where the server will behave differently depending on what FQDN the client is attempting to contact : web servers, FTP servers, etc. Others don't, because it doesn't make sense, or because the protocol used doesn't support such thing (HTTPS, for example).
If you want a more specific answer, you need to defined what you want to do. Odds are, you are talking about websites - the other replies to your mail should have answered that point.
Best,
B
