I recently decided to configure dynamic DNS on my Cisco router at home. Lately, my ISP has been giving me issues causing my IP address to change quite often. Since I don’t pay for a static IP, I use dynamic DNS services to map my IP to a DNS name.

I usually just go to the website when my IP address changes, but I decided I wanted to let my router do the updating for me.
