DNS Server
 

Just a question, not sure if its a dumb one or not but would like to know tho

Setting up your own DNS Server on Ubuntu help me out

I have a ddns IP always changing,my domain is hosted by my ISP, right now I usually have to log into my control panel/DNS to change the IP manually when needed.

What use is setting up your own server? What happens when the IP that your DNS server is running on changes?

Don't run your own DNS server. Don't.

If your domain host doesn't provide a mechanism for this already (have you asked them?) then I would recommend using zoneedit.com to provide your DNS which has a number of ways to automatically update entries. You'd just tell your domain registrar to use zoneedits dns servers for NS records and it's done.

Hi
