I created a new dreamhost account and when I signed up, I said I already had an existing domain and just wanted to host at DH. I entered my exsiting domain name (for example mitchrapp.com). It shows up in my account under manage domains. I would like to build up a new wordpress site and have everything working before updating the DNS for mitchrapp.com (and/or transferring the registartion to DH). What is the best way for doing this and being able to view the test site over http without having a static IP address?
