RFC 2606 (& 6761, section 6) reserves the following TLDs for private testing:
.test
.example
.invalid
.localhost
(These were created for testing, not for production.)

http://en.wikipedia.org/wiki/.test
http://en.wikipedia.org/wiki/.example
http://en.wikipedia.org/wiki/.invalid
http://en.wikipedia.org/wiki/.localhost


'.local' is reserved as a pseudo-TLD for link-local hostnames that can
be resolved via Multicast DNS http://en.wikipedia.org/wiki/.local


Similar to 'localhost', '.localdomain' is "reserved" for internal usage.

Hence the traditional default 'localhost.localdomain' on new installs.

Also regarded as "reserved" are the other pseudo-TLDs mentioned.

Cool,
