I'm sharing a dreamhost account with a friend: each one of us share this space and he already has 2 registered domains. I have none. I mainly use it to host some other friends systems.
I'm planning in doing a small specific website, but I dont want to ask for my friend to create a subdomain for me because it doesn't make any sense to his websites.
What I wanna know is: is it possible to use a dyndns account (mydomain.dyndns.org) or similar to point to a directory in dreamhost as if it was a domain? If so, what do I need to do to accomplish this configuration?
EDIT: Thanks for all your answers. I don't plan to buy a domain since I don't have a credit card and here in my country the domains make public some personal information (like a "social security number" equivalent I think) that I don't agree with. And the domain is a test, it's possibly to change, so I would just test it and "throw it away" after the testing.
I've found a "free domain service for the first year", http://www.co.cc/. But I don't know this company so well, and I know that dyndns is a good one.
I'm not so experienced in dreamhost's panel and DNS, sorry if this is too "noob". Do you know which tutorials should I read about DNS concepts and dreamhost to setup a dyndns solution like the one proposed by hark?
