The command format of the arp command to bind the IP address to the physical address and the command

Run cmd

arp -s [need to bind IP address] [MAC address to bind IP] e.g. arp -s 00-23-cd-85-bc-02 can be used to effectively prevent ARP attacks

For Windows 98 ME, run "winipcfg", the IP address you see in the dialog box is, and the "adapter address" is the MAC address of the network card. In Windows 2000 XP, if you want to enter "ipconfig all" in the command prompt, the "physical address" in the display list is the MAC address, and the "IP address" is the IP address. To bind the two, enter "arp -s ip address mac address", such as "arp -s 54-44-4b-b7-37-21", and arp has three parameters after it: s, d, a; Their respective roles are to bind, unbind, and view their status Answer:

To use an analogy: arp -a

Get: 00-11-22-33-44-55-66 then type: arp -s 00-11-22-33-44-55-66 Finish Note the spaces.

It's okay to help with the routing.

In this way, even if others change to the IP of machine A, they will not be able to access the Internet.

1 First we open the desktop of the computer, in the start menu, click Run, or you can press Win R, and then open it.

2 Enter cmd in the dialog box and click OK.

3 Type ARP A and press the lane key. Then you will see the information as below and record the internet address and physical address in the diagram below.

4 Enter the ARP SIP address and the physical address, where the IP address and the physical address are the two addresses you recorded above, and click the Enter key to bind them.

5 Enter ipconfig to view the bound IP address.

arp -a is to see the physical address (MAC) corresponding to the network address (IP) you have learned, and of course your gateway MAC

ipconfig all is to see the configuration of all your own network cards, and of course you include your mac

arp -s is used to manually bind the physical address (MAC) corresponding to the network address (IP).

The principle of the Cyber Enforcement Officer is to interfere with your learning of the correct MAC address of the gateway. You can use arp -s to bind manually. Example.

The IP of your gateway is 00-11-22-aa-bb-cc then you can use it"arp -s 00-11-22-aa-bb-cc"

Then you can see it with arp -a.

internet address physical address type

00-11-22-aa-bb-cc static

Note that the type of manual binding is static, and the automatic learning is dynamic

It's not hard. Use the arp -s command.

Open: Start - All Programs - Attachments - Command Prompt.

Enter in a window at the command prompt.

For example: arp -s 11-22-33-44-55-66 binds.

Prevent some ARP spoofing attacks after binding. So that your machine always knows the correct address of the gateway.

ARP -S 22-CB-AA-11-22-22 is the IP address of your gateway.

22-cb-aa-11-22-22 is the MAC address of your gateway, and of course there is also a batch.

echo off

if exist del

ipconfig /all >

if exist del

find "default gateway" >for /f "skip=2 tokens=13" %%g in ( do set gateip=%%g

ping %gateip% -n 1

if exist del

arp -a %gateip% >

for /f "skip=3 tokens=2" %%h in ( do set gatemac=%%h

arp -s %gateip% %gatemac%del

deldel

exit

In fact, it is very simple to attack, enter first.

Binding is used.

duarp -s view is to use arp -a to delete the previously bound arp cache table, need dao to use arp -d, then delete.

Note that after using the arp -d command, the entire arp cache table will be emptied if you want to remove the arp binding for a single IP. Use a command like arp -d. You don't need to add a MAC address.

Start - Run - cmd, enter arp to have a specific way to use it.

If the instance is in Win7 or later, CMD must be run as an administrator.

Since you use ARP binding, it means that you are a local area network bar?

Can you access the Internet without a command to change your IP? Edition.

Maybe the admin is in power.

The route is set. So if you change the IP, you can't get on it.

Then you should have the IP address to see if you can ping the gateway?

arp -d can remove all static and dynamic ones.

Do you have any ARP firewall, turn it off first. Make sure you can ping the gateway first.

You restart your computer and the bindings are gone, and then you're ready to go. ARP bindings are one-time.

The best way is to bind the IP MAC address on the router, even if someone else steals your IP, he will not be able to access the Internet.

Then find the host of the stolen IP through the MAC address, and record the MAC addresses of all hosts in advance through administrative means of punishment, when the IP address is stolen, use the ping command to ping the stolen IP, and then use arp -a to display the MAC address corresponding to the IP address, and through the recorded MAC address, you can find the corresponding host.
