In the process of data communication, the correct correspondence between MAC address and IP address is key to ensuring accurate data transmission. If there is an error in this correspondence, it may lead to data mistransmission, which will affect normal network communication. Through some technical means, maliciously modifying the mapping relationship between MAC address and IP address will prevent the device from connecting to the Internet normally, which is called ARP spoofing. For more detailed operations, please refer to the collation information provided by www.xp74.com. It is important to note that such operations may undermine the stability of the network environment, so it is important to exercise caution and strictly abide by the relevant laws and regulations of the country.
- After logging in to the router, enter the LAN port status page to query the MAC address information of the router.
-
For computers that are offline, click the Start menu, select Run, and enter cmd to open the command prompt interface. Then run the command arp -a to check the ARP cache record on the current machine. Normally, these mappings should match the correspondence between the IP address and MAC address displayed on the router.
-
If the MAC address associated with the gateway is not the actual MAC address of the router’s LAN port after entering arp -a in the command line, it indicates that ARP spoofing may be in the system.
