What 'services' are my Domain using?

[Ibrahim Hughes]

I have a website on Investor carrot and our email services on Yahoo. We now wish to switch from Yahoo to Google with our email but keep our website on Carrot.

I was talking with the service rep on Yahoo before I realized that I'm not sure exactly what services are where. But BEFORE I can even determine whose managing what services, I need to know WHAT those services actually are. Is this a complete list? Once I identify all of the services I can make sure I understand who has what and then communicate with the appropriate party as to what will be changed and how it will affect the other services, namely the website.

So I'm hoping the BP techies will help me out on this (what should be a) short list of what services our domain is using:

Email: Yahoo

Wed Hosting: Carrot

Domain Services: Yahoo?

DNS: ? 

FTP: ?

Are there any others? Thanks in advance.
