This gets a bit confusing, so just read through the entire thing before throwing in your $.02. I have a domain that is currently parked with Go Daddy (Host 1). I would like to actually use this domain now. I was thinking about going with DreamHost (Host 2) for the web site and FastMail.FM (Host 3) for the email. I would like to keep Host 1 as the domain host because of their extensive DNS controls and don’t trust Host 2 with this. I will get a static IP with Host 2 and just change the MX record to Host 3 for email. Now, here’s my question: Can I just change the A record with Host 1 to reflect the IP of my site with Host 2 without running into problems? Go Daddy seems to think I can do this by changing the IP address in the A record to the static IP I get from Host 2.
I realize I could solve all of this by just sticking with one host, but I would prefer to do it this way unless it’s going to cause problems. Maybe I’m just crazy (or don’t fully understand how networks function).
UPDATE: I went ahead and did everything this afternoon and it all works just fine.
