I know this is the risky way to do it, but the IT guys for a client of mine is using the "A Record IP Address" to point the domain name so they have more control over the DNS settings on their own server. (They aren't using ns1.dreamhost.com, ns2.dreamhost.com, ns3.dreamhost.com). I'm considering upgrading to Dreamhost PS. Will my IP Address change? Or would this be a good time to convince them to use the dreamhost servers to point the DNS, rather than managing it on their own servers?
