do my laptop and desktop have the same ip address? excuse me if this is a dumb question lol
technically, no, but the IP address being looked at is not the internal (in your home) IP address. the outside world cannot see beyond your router to know how many devices you have connected to it. The IP address being looked at by AMT is the external IP address, the one distributed by your internet provider.
Very simplified description of network routing:
desktop IP: 192.168.1.2/ laptop IP: 192.168.1.3>-Gateway/Router/Modem (Internal Private IP: 192.168.1.1 External Routable IP: 65.55.34.12)>-<ISP IP 65.55.34.1
Public Internet cannot see beyond the 65.55.34.12 IP Address so it does not know that there are two devices online. It only knows that there is one device online, the Gateway/Router/Modem. The Gateway distributes IP Addresses that are classed as private/internal/non-routable addresses to your home network. The ISP distributes public/external/routable IP addresses to its customers' routers.
So, if you're trying to take the same hit from two different devices connected to your home network, you cannot. AMT can only see the 65.55.34.12 address and therefore that would be two different attempts to take the same hit from the same IP Address.
