* Subdomains

* Top-level domains (real or made up). You probably do not want to use one that exist, otherwise you will not be able to reach it from your home network.

If your domain is the default, '''home.com''', the machines in your network will be known for example as:

* machine2.home.com

* etc.

If your domain is '''joe''' (a top level domain), your machines will be known as:

* machine2.joe

* etc.

... you get idea.
