Question Bind9 with a dynamic IP?

So, trying to research a solution. I'm running a private server with Ubuntu 12.04. Unfortunately, my ISP won't permit me to place a static IP on my router. I leave home for months at a time, and in that time span my external IP would change, thereby preventing me from accessing my server. I didn't know if it would be possible to install Bind9 and nsupdate or something else to give my router a domain name with an underlying service that updates the ip address assigned to my server. My server already has a static IP as reserved by my router, but other than that I'm not sure what to do. Any help?

I presume that you want to get into your server when you are away.
You don't really need bind9 to do this.

Have a look over here :

Chances are your router supports some sort of DDNS already.

There is a free service at :

The idea is that your router contacts the DDNS service provider several times a day telling them what IP it is living at. The provider will update its records as to where your server is, and you just use the assigned domain name that you choose when you sign up for the service.

This is a basic setup, with no reverse lookups etc. But it will get you into your server while you are away.
