You can see your network adapter’s MAC addresses by using the command prompt in Windows with the ipconfig /all command. (I’ll talk about that “should” more in a moment.) No two anywhere should have the same MAC address. As you’ll see in a moment, IP addresses are assigned as part of connecting to a network, and MAC addresses are assigned at the time hardware is manufactured.Įven hiding a MAC or IP address is a concept that doesn’t quite apply, but we’ll get in to that too.Īnd whether MAC or IP addresses are hidden or not, they are not the kind of things you should be spending your time worrying about to stay safe from hackers.Ī MAC (or Machine Access Control) address is best thought of as kind of serial number assigned to every network adapter. Well, the last one is easy to answer: there’s no concept of free versus paid IP or MAC addresses.
