I am triying to configure my domain name and I need write domain name and its IP
are these data right?
The DNS servers you have there (ns1, ns2, ns3.dreamhost.com) are correct, but the IP addresses you are using are incorrect for these servers. (It looks like you're trying to use the IP address of your web site, which isn't what you want here.) The correct IP addresses are available at http://wiki.dreamhost.com/DNS.
