What is ARP Protocol?

ARP is an abbreviation for Address Resolution Protocol. It is a link layer protocol that works at the second layer of the OSI model. It connects this layer with the hardware interface and provides services to the upper layer (network layer). We know that Layer 2 Ethernet switching devices do not recognize 32-bit IP addresses, they transmit Ethernet packets as 48-bit Ethernet addresses (often referred to as MAC addresses). That is to say, IP packets are not identified by IP addresses but MAC addresses when transmitted within a local area network, so there must be a correspondence between IP addresses and MAC addresses, and ARP protocol is used to determine this correspondence.

Solution 1:

1. Binding IP and MAC addresses

Specific operation method: Open the router management interface, click "IP and MAC bonding"→"Static ARP bonding settings" item, and then click "Add single item" button on the right side.

2. In the "ARP Static Bonding" window that opens, enter the IP and MAC to be bound, and then click the "Save" button. Use the same method to bind IP and MAC addresses to other computers in the local area network. Finally click on the "Make all entries effective" button.

3. Use network protection software to bind gateway IP, open "360 Security Guard," click "More" button in the main interface of the program.

4. Click "Traffic Firewall" in the program list, and then switch to the "local area network protection" tab in the open window.

5. Then set the "Gateway Binding" mode to "Mobile Binding" and click the "Details/Settings" button.

6. In the "Add Protection Gateway IP and MAC" window that opens, click the "Add Gateway" button to manually bind the gateway IP and MAC addresses.

7. The ARP conflict phenomenon of the local area network will be effectively contained, and the network speed will be normal at this time.

Solution 2:

1. Right-click in the blank space of the computer desktop and select New Text Document;

Copy and paste the following code into Notepad:

@echo

title "Automatically clear arp cache"

color 2

mode con cols=50 line=4

:cleararp

@echo arp cache clearing...

arp -d

cls

goto cleararp

Click File-Save, or use Ctrl+S.

4. Then right-click the text document, select Rename, change the suffix of txt to bat, and then click the mouse in the blank space of the desktop, and click "Yes" in the pop-up interface;

5, just need to double-click the cache file, will automatically clear the arp cache.
