I need to buy it for someone don't know where to buy it? i know some sites who provide it for free. But i want it with hosting? any sites from where i can buy it?

If I am correct, then you need Dynamic DNS service only if you are trying to point a domain to the server with dynamic IP. Let's say that your server (could be home computer) have no static IP, then you need it to point the domain to your computer - every time your IP will change your comp will instantly notify the DNS server and changes will apply.
If you are using server with static IP you don't really need this.

You're absolutely right. But from where i can buy it? i don't have to use a free service.

I think that you have to search trough the services DNS services. Check your domain registrar - maybe even this servce have such options. Or just type "Dynamic DNS service" in Google and check. You'll find even softwares that will allow you to set up own DNS server and then offer this service to the others.

Actually, freedns.afraid.org does offer a paid service with more features. Spend some money and help out those who use the free service
