Angry IP subnet obtains the IP address of the device.
This software is used to scan the IP addresses of hosts in a certain CIDR block. Through usage discovery, the principle is to quickly ping each ip
The main API getnetworkparams () and getadaptersinfo () functions enumerate all network adapters in windows, print the IP, gateway, and Mac, and convert the MAC address from hex to string.
