Best way to redirect dynamic ip?

I have emailed for domain name host but they haven't got back, well they let you forward your domain name to wherever(my own server in this case), so if i have a dynamic ip is the only thing i can do is to say redirect it through a free dynamic dns provider like http://www.no-ip.com, so that i can constaly have my ip updated by the no-ip client ?

If you have a domain name (with an IP address), yes - that's how most of us do it. If you have the domain name hosted somewhere, then no - it's a static address, so you just use that static domain name.
