possibility of eavesdropping on the conversation between A and B. Continue to think about the above example:
C pretend to be A postman, first tell A: "I am A postman" (host C sends A constructed response packet to A, the source IP address is G 192.168.1.1, the source MAC address is the MAC address of C). Stupid A easily believes that the message "C is A postman" is recorded in his mind;
C then pretends to be A and tells the Postman: "I am A" (C sends A constructed return packet to the Gateway G

What is ARP?ARP (Address Resolution Protocol) is a low-level protocol located in the TCP/IP protocol stack. It is responsible for resolving an IP address into a corresponding MAC address.What is ARP spoofing?From the perspective of Affecting Network Connection smoothness, there are two types of ARP spoofing: one is
(note that the ARP table can be set to static in the routing ). That is to say, the corresponding table will be refreshed by the host as needed. This is becauseEthernetTransmission on the subnet layer is determined by a 48-bit MAC address. Generally, before a host sends an IP packet, it needs to find the MAC address corresponding to the IP packet in the conversion table. If not found, the host sends an ARP broadcast packet, which looks like this: "I'm host XXX. Mac is xxxxxxxxxxx, IP is XXX.

In the internal networks of many schools and companies, some immoral people often use ARP to spoof software and attack others, dropping many people or even paralyzing the entire network. To address this issue, you can take the following measures.

clearly see that the host does not have the MAC address corresponding to this IP address before it communicates with 192.168.7.119. However, after communication, now we know the MAC address of the other Party. In Windows, the MAC address of the other party is stored in the ARP cache. to save network resources and communication time, most operating systems keep an ARP cache table that records the IP addresses and MAC addresses that were previously accessed, once there is a new ARP broadcast in
hosts on the network will check whether the destination IP address in the packet is the same as the IP address of the host. Ignore this packet if they are different. If they are the same, the host first adds the MAC address and IP address of the sender to its ARP list. If the ARP table already contains information about this IP address, then, the target host sends an ARP response packet to the source host, attaches its MAC address, and tells the target host that it is searching. 4. when the so
) it is a legal response, as long as you receive the ARP reply package or arp broadcast package (including ARP request and ARP reply) of the target MAC, it will accept and cache it. This provides the possibility of ARP spoofing. malicious nodes can publish fake ARP packets to affect the communication between nodes in the network, or even act as a "man-in-the-middle ".
