    How to create a Dynamic DNS server?

    I was told that it was possible to setup a dynamic dns server on linux. How would you do it?

    Re: How to create a Dynamic DNS server?

    Maybe I need to be more specific. I've been running linux for about 2 years, so I'm still learning.

    When you want to create a web server at home, usually you have to setup a dynamic DNS through your router with something like DynDNS.com so that you can link up your domain name. Mine which I got through godaddy is: www.bencookemusic.com

    I'm sitting behind a router here, however DynDNS.com doesn't really work. I have to keep going to the website and update my IP address manually.

    Someone told me that I could set up a Dynamic DNS server that would work better and it would be on my server, instead of using a 3rd party service.

    I would like for my internet/public IP address to be updated with www.bencookemusic.com without using a service like DynDNS.com

    The only reason I am being more specific and asking for the answer here, is because It's hard to find exactly what your looking for on the Internet when you're not as knowledgeable about the subject as many of you are here. Sometimes you think you've found the answer and the website you read is not even close.

    setting up your own DNS server, "dynamic" or not, is not going to help here, because you have no control over your ip address, your ISP does. That's why you need ssomething like dyndns

    to avoid the manual updates, you can run somthing like ddclient on your server. It will manage the updates for you

    Well... maybe you're not quite understanding how this is supposed to work.

    Your friend is partially correct. There is a couple of clients for linux (inadyn and ddclient - I prefer the latter) that will update your DDNS service for you. So you're not really running a DDNS service on your machine, you're just running a DDNS client that updates your DDNS service... make sense?

    So there's no way around having to use a service like DynDNS.com? Unless I get a static IP of course.

    correct

    edit:
    or maybe ...
    you could mimic DynDNS by setting up a DNS server yourself, make it authoritive for your domain, then monitor changes in the IP address your ISP assigns to you, and modify the A and/or CNAME records in your DNS when needed, either manually or with an automated solution of some sort.

    I'll have to do some research on this.

    What's wrong with dyndns? I've used their service for years for free, I love it. Very simple to setup, and does exactly what I need it to do - update my domain if my IP changes.

    I am lucky up here in Canada, we have static addresses that stay the same year after year.

    I log into my domain registrar, not for IP changes, but to look at the logs.
    SERVER: Azure datacenters, Hyper-V
