client to alleviate the requirements for an Internet name
With this package the user can have an Internet name for his host
even though he might not have a name server or a static IP. It works
by being a client of a supposedly open name server and updating the
server's records when the need arise. A partial list of the servers
that are supported is http://{www.dyndns.org,freedns.afraid.org,
www.zoneedit.com,www.no-ip.com}. Some of the services of these servers
are free of charge.
This is a command line tool that is written in portable ANSI C with a
little OS abstraction layer. It can maintain multiple host names with
the same IP address, and has a web based IP detection which runs well
behind a NAT router.
