How do I bind the IP address in the ARP table to the MAC in the program? 30

If the MAC address **:A is changed to the subnet of A, then B and A are no longer on the same network segment, because there is no gateway, then ping B on A will fail, and B cannot be accessed if it is not the same network segment A.

1. Routers, and even all routers don't have this function, ARP is an address resolution protocol.

No ARP is an unjustified calendar to get MAC addresses.

List, that is to say, it is impossible to enter the data exchange and routing of the trace, so it is impossible to implement MAC hiding.

2. You can only temporarily modify the MAC address to go online, if others find it and then seal it, it is still useless; As for the MAC address modification method, there are many articles on the Internet, just search for it, and I won't list it here.

First, get the intranet of the security gateway.

(e.g. the MAC address of the Hiper gateway address is 0022aa0022aa).

Write a batch file.

and MAC address to the actual gateway IP address and MAC address used). Drag this batch software into the Windows Start Program Launcher.

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.

Static ARP setting is to prevent hackers from impersonating your MAC to get your IP to prevent you from surfing the Internet, the specific IP and MAC binding settings static ARP binding operation steps are as follows:

1. First of all, we open the desktop of the computer, and in the start menu, click Run. Or you can press the key combination Win+R to turn on the run.

2. Enter cmd in the dialog box and click OK.

3. Enter arp -a and press enter. Then you will see the following information, and record the Internet address and physical address in the figure below.

4. Enter arp -s IP address and physical address, where the IP address and physical address are the two addresses you recorded above, click the enter key, and then the binding is realized.

5. Enter ipconfig to see the bound IP address.

1.If the subnet of A is changed, then B and A are no longer in the same network segment, because there is no gateway, then ping B on A is a failure, and B cannot be accessed if it is not the same network segment A, so the two machines will not.

There are each other's macs; "destination host unreachable" indicates that the other party does not exist because it is not.

Same CIDR block. 2.Because the code of B is, it determines that A and itself are in the same network segment, so it can be accessed.

The other party, but machine A may have turned off the ping switch, although the ping A timed out and did not respond, but the corresponding MAC was successful, so both parties have each other's MAC; "Request timed out" indicates that there is no response after the timeout, but the MAC address is used.

is successful, so, unlike Scenario 1;

3.IP addresses must be converted to MAC addresses using the ARP protocol, case 1, the addressing is unsuccessful, and case 2, the addressing is successful, so the prompt is different.

Hehe! I'm a webmaster, and I understand these questions.

Their network segments are different, A's subnet is 24-bit, ping is differentB, B can ping A, but there is no packet back, so it shows that there is no ping, but it is actually passed.

The address is the identification code of the network card, the MAC address of the network card is not the same, and the bottom layer of the LAN is accessed by the MAC address;

The network is accessed with an IP address, and when it is implemented internally, the same network segment must eventually find the MAC before it is implemented.

For mutual access, MAC address is a low-level means to achieve IP access;

3.ARP is responsible for converting IP into MAC address to achieve network access;

The MAC address is equivalent to the ID card of the network card, which is unique in the world.

The IP address has nothing to do with it, but it will work when some DHCP bindings, which is equivalent to binding your ID card and your name together to be the same as you.

ARP is a protocol to obtain your IP address, which is equivalent to a protocol where others can read your ID card.

Enter the arp -a command in the runtime to check your arp status, then make a text file and enter it in.

echo off

arp -d

arp -s

xx-xx-xx-xx-xx-xx

The X above is your IP address.

The X below is your MAC address.

By typing arp -a you can see this data for you.

Then rename this txt file to. bat

Put it in the windows program and have a boot startup, drag it into it, this in order to prevent others from using some network management tools to tamper with your ARP to automatically refresh your ARP and MAC every time you start, in fact, you don't have to be so troublesome, there is a binding function in Qihoo 360 security guard real-time protection.

After opening the main panel of Qihoo 360 Security Guard, you can see that there is a real-time protection option, and then click on it, you will see that there is a setting, and you can see that there are 4 options in the following function settings:

System Firewall, ARP Firewall, Protection 360 Guard, 360 Active Defense Service.

Tap on the second ARP firewall.

Then click Manually bind the gateway.

Then according to your IP mac gateway to set it up, the gateway is generally your default gateway such as.

You can also set others, but you need to change the MAC address accordingly.

Let me show you my settings. **As follows.

It is true that ARP attacks are very depressing, and the network speed has also slowed down, because this attack has caused a lot of load on the router.

Resources are wasted.,It's recommended that if it's to maliciously control other people's networks,It's best not to use it.,In addition, the color shadow ARP firewall is still quite easy to use.,It can resist ARP attacks.,It's better than 360 and Kingsoft.,Personal feeling.。

There is a free version as well as a paid version.

1. Run the Command Prompt (cmd) with administrator privileges.

2. Run "netsh i i show in" in the command prompt to check the IDX number of the NIC to be ARP bound.

3. Run "netsh -c "i i" add neighbors idx ip mac" in the command prompt to bind arp, where idx is the idx number of the network card found in the previous step, and ip and mac are the ip address and mac address you want to bind.

For example: netsh -c"i i" add neighbors 12 d0-27-88-c9-7c-a4

4. Finally, use the "arp -a" command in the command prompt to check whether the arp item you added is in the list and static. The reboot takes effect!

Unbinding: netsh -c "i i" delete neighbors IDX (IDX is changed to the corresponding number) to delete the MAC address binding, and then reboot the system.

ARP bindings don't solve the ARP problem. Anti-ARP is a big and difficult problem, there are many anti-ARP tools on the Internet, the principle is to automatically bind the local machine and the gateway IP MAC, ARP attacks generally use the gateway and the terminal two-way binding, the terminal installs the ARP firewall, but this method can not prevent the spread of ARP spoofing packets in the network, and even the IP MAC address bound by the ARP firewall is wrong, our company has always been attacked by ARP before, binding, after installing the ARP firewall, although it is not dropped, But with the packet capture tool found that there are a large number of ARP packets on the network, resulting in the ping gateway although there is no delay, but always packet loss, very depressed, and then a classmate of the computer city introduced the thriving multi-wan immune wall router, it has ARP innate immunity function, it installs an immune driver at the terminal, can completely control the sending of terminal ARP broadcast, it happens that the company has two ADSL lines, now it is very good to use, the network is very smooth, and the data traffic of each terminal can be monitored. Not only does it completely eliminate ARP, but the monitoring of the network is also very convenient, intuitive, and very easy to use.

DHCP is the dynamic allocation of IP, if the router or switch has DHCP static binding enabled, then the newly connected computer will automatically assign a bound IP according to the MAC address, which is set on the computer network card to automatically obtain IP.

If the computer has set up other IPs in the network segment that can access the Internet, and does not need DHCP allocation, it can also access the Internet, and similarly, when other PCs have configured the IP, then the bound PC cannot be used normally when it goes online.

ARP binding, on the other hand, directly binds the MAC address to the IP address, even if the IP address has been configured on other PCs, then when you look up the MAC corresponding to the IP on the switch or router, you will not be able to find other PCs.
