Static IP address binding details example

In static IP, if you use a Layer 3 switch, you can limit the IP address on each port of the switch. If someone changes their IP address, then his network will not work. We now explain an example of the binding of a static IP address.

View the MAC address of the network card

Click on “Start”, select “Run”, then enter the winipcfg command in it, you can find out your network card address.

After logging, go to the proxy server and let the network administrator bundle the static IP address you have on the Internet with the network card address of the recorded computer. The specific command is:

ARP-s192.168.0.400-EO-4C-6C-08-75

This will put your static IP address on the Internet (assumed to be 192.168.0.4) It is bundled with a computer with a network card address (assuming 00-EO-4C-6C-08-75), and even if someone else steals your IP address 192.168.0.4, it cannot access the Internet through a proxy server. It should be noted that this command is only useful on the proxy server side of the Internet, and it is also a static IP address. Like the normal Modem dial-up Internet, the dynamic IP address does not work.

Function introduction of ARP parameters

ARP?-s??-d??-a?

-s—— corresponding IP address and physical address Bundle.

-d——Delete the bundle of the given IP address and physical address.

-a—— Display the IP address and corresponding physical address by querying the Arp protocol table.

As a network administrator, if the binding of MAC address and IP can be flexibly and skillfully used, it will create a very safe and favorable environment, which can greatly reduce security risks.
