1. By querying the IP address of the other party between the local area networks, the Mac address of the other party can be mapped to the APR buffer table of the host. Map host IP address to Mac
First query the shared LAN host through net view
Second: randomly select a computer name, force the use of ipv4 to get the IP address, and after ping the same, the ARP table is updated in the ARP buffer table, and the current IP address and the corresponding Mac are added.
The third obtains the APR buffer table of the host
Fourth, map the obtained Mac address to the IP address of your own host
In this way, you can successfully map your own IP address to the Mac of other hosts in the local area network. A common form of swiping. However, there is no account setting on the campus network. It should be that the IP address and the Mac address are bound, otherwise how can the school charge for it.
