Ugh. Generally, I'm just really confused about this. I currently have my site hosted in my living room, but my upload speed is so slow that I wanted to move it to DreamHost.
At DynDNS.org, I see no way to change my DNS names. I get the feeling that if I could setup DreamHost to tell DynDNS to point my domain to it's website that I'd be all set. Yet, I don't see that option, either. When I try to 'transfer' the domain to DH, I get an error message on the button (which I wrote to support about).
My previous config: setup my router at home to tell DynDNS where my webserver was. The router had my username and password with DynDNS. How in the world do I get the domain to point to my account on DH?
