inadyn | client to alleviate the requirements for an Internet name | Mehr ...
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.
