DNS updates are propagated across multiple locations and it takes time before they all share the same information.
If you are on Windows, try running the command 'ipconfig /flushdns' from a Command Prompt window. Keeping that window open, you can run 'nslookup captivereefs.com' to see what IP address you are getting now. If you want to know what it should be, run 'nslookup captivereefs.com ns1.dreamhost.com' and the DreamHost nameservers will tell you directly. Naturally it should match what you get for 'nslookup www.captivereefs.com' already though.
For me currently both hostnames are traced back to DreamHost.
