Question : Setup Web Site using Dynamic DNS

I have someone who wants to setup a website on their home network. They cannot order a IP address from their ISP since they do not offer it to residential customers. So I heard using DynDNS (Dynamic DNS) is the way to go.

They already have a domain name registered and I have server 2003 setup at their home and all the routing has been setup. I just need to know how to setup Dynamic DNS to work with an already registered domain name.

I have looked at the following sites;
freedns.afraid.org
dyndns.com - appears to only offer third level domain names like myservername.dyndns.com

Thanks!

Answer : Setup Web Site using Dynamic DNS

I run my own personal websites on a Dynamic IP address and do the inbound routing as follows:

- Create a subdomain at the ISP. I usually use www2.domain.com
- Redirect www.domain.com to www2.domain.com
- Configure www2.domain.com's DNS to be a CNAME, with the CNAME record the DynDNS domain you created

This means traffic will be forwarded to www2.domain.com, which then - via DynDNS - resolves to the IP of the web server. Provided port 80 is open and the web server is listening correctly, the request should then be answered.

I don't do a CNAME directly on the www.domain.com (although you could) because it causes issues with any email addresses for that domain.
