Practical: three solutions to IP address conflicts

Why is there a sudden IP conflict?

In a LAN, IP addresses of computers, mobile phones, and other devices are automatically assigned by routers. When two or more devices have the same IP address configured, if the subnet mask is the same, an IP address conflict occurs. Of course, it is not ruled out that you have manually set an IP address that has already been used in the LAN.

So how can we solve the IP conflict problem?

Restart

You can try restarting the computer first (yes, that is, the omnipotent Restart Method). After restarting the computer, check whether the computer can obtain a new IP address. If there is no IP address or an IP address conflict occurs, use the second and third methods below.

Manually modify the IP address of the computer

① Open "network and sharing center"-"change settings"-Right-click "WLAN" or "Ethernet" (local connection) -Select "properties" and double-click "Internet Protocol (TCP/IPv4 )";

② If your vro management IP address is 192.168.0.1, you can set the IP address to 192.168.0.xx and XX to 2 ~ Any number in 254, and then click OK. Of course, some routers enable an IP address pool after 100 by default. Therefore, we recommend that you use the number of 100 + for XX.

Enable Firewall

IP conflict may also be caused by the ARP virus. ARP is usually a prompt of IP address conflict, which means that the webpage can be opened very slowly or even cannot be opened, it even causes network paralysis.

Solution to ARP virus: first, clear the ARP virus source. If your computer is infected with viruses, you can directly use anti-virus software (such as 360 security guard) to kill the virus, then enable the arpfirewall for active defense.

By the way, to avoid IP address conflicts, you can also use the "static IP Address Allocation" function to bind all devices in the LAN to a fixed IP address, in this way, you are not afraid of IP conflict.

PS: Data on storage devices such as hard disk, USB flash drive, CD, and SD card is lost. The mini rabbit data recovery software (minitool) is used for recovery, it has five functional modules: "deletion recovery", "formatting recovery", "Hard Disk Recovery", "deep recovery", and "Mobile storage device recovery", with high recovery efficiency, security is guaranteed.
