you can host your domain for free. i believe you need to set your nameserver to the following
Primary : ns1.dynamicname.com ip:216.198.214.3
Secondary : ns2.dynamicname.com ip:12.37.165.130
i'm really not the professional at all this so lets wait for some more details from someone who know's what they are talking about, but yes you can host the domain for free.
