Each computer on your network has an IP address. The IP address is the unique ID that allows routers and other computers to find your machine and deliver messages. An Exchange server is a Microsoft product that hosts email communication. You configure your email client to point to the Exchange server, which sends and receives messages for you.
If you want to know the IP address of the Exchange server, you need to look up your Exchange server name in account settings and use a command line tool called 'ping.'
