[app] Inadyn dynamic DNS client
 

From TFWS:

"INADYN is a dynamic DNS client. That is, it maintains the IP address of a host name. It periodically checks whether the IP address stored by the DNS server is the real current address of the machine that is running INADYN."

" * supports the following dynamic DNS services:
* dyndns.org (in all three flavors: dynamic, static, custom)
* freedns.afraid.org
* zoneedit.com
* no-ip.com
* maintains up multiple aliases of the same IP address
* runs as a service (Windows 2000/XP, Linux)
* or runs as a console application
* updates the correct IP address even behind a NAT router.
* supports access via http proxy
* does not perform unnecessary updates.
* has 'install and forget it feature'. That is, after install one can completely forget about it. No maintenance required. (as long as no bugs are found;-)
