There have been a few domains which are permanently reserved and will never be assigned elsewhere:

You can reasonably claim to be part of your ISP's domain, if you prefer.
.lan might be reasonable, or .local, although the latter might conflict with Bonjour/Zeroconf.

It's mainly used to setup the default search domain which clients use to find local unqualified hosts.
