I support a 40 user, mixed OS, small company. I have installed Bootcamp on a new iMac. It is running OSX Yosemite and Windows 7. I will be adding both machines to an AD domain. We assign static IP addresses to our computers because we use term emulation software to access a D3 database. Should each OS have different static IP addresses? They will probably have the same MAC address. They have different computer names. Any thoughts?
