Configuring Dynamic DNS on Cisco Router
Most of the network administrators got a problem on how to track their Dynamic IP address. Now, we will setup our router for DDNS. With this configuration we can easily track our Dynamic IP address by mapping it to a name (e.g. router.dyndns.org).
Steps:
[1] Register to no-ip.com or dyndns.org for free (We will use DynDNS.org as an example).
[2] After we setup our account at no-ip.com or dyndns.org remermber your username/password and hostname (e.g. router.dyndns.org)
[3] Configure the Cisco Router.
