Domain name for local network?

[Jonathon McKitrick]

If I have a couple of boxes in a home network that connects to the Internet
via ppp, is there any way I can name my network?  I don't want to register
a name, just use it locally.  This way I can refer to 'neptune.jonathon.org'
or something similar rather than '10.0.0.1'.

NOTE: Please CC me, as I am not currently subscribed.  Thanks.
