DynDNS Update

[example outputs]
This script allows one to update a specified subdomain registered at INWX.de with a new IP address. While this IP will most probably be the publicly available IP of your router, it is possible to set the domain record to any valid public IP address.

Since this effectively allows you to create your own dynamic DNS service, you no longer depend on the limitations of free dynamic DNS services.

In order to easily run the script from the command line, I defined the following shell alias:

alias dyndns_update='~/bin/dyndns/update_domain.sh'

The picture on the right shows the two possible use cases:



BASH script; Linux; dynamic DNS.
