Computer automatically switches IP

The company network IP address always changes automatically

The reason is as follows: Check the DHCP server of the company's LAN to see if the address in the address is saturated. Is the lease time of the DHCP server too short? The server settings corresponding to the client are likely to have a lease time that is too short or does not automatically renew.

You can use some network monitoring software to monitor the IP configuration of LAN computers. Currently, there are some network monitoring software in China that can manage the IP and MAC addresses of computers on the LAN.

It is very normal. Usually the IP addresses within the company are automatically assigned by the dhcp server. If the dhcp server lease time is set to be relatively short, or the dhcp server is restarted frequently, the IP address will be changed more frequently. . You can avoid this problem by extending the dhcp lease time.

Why does my IP address always change automatically?

Network failure is also one of the reasons for the change of IP address. A network failure may cause the network service provider to reallocate the IP address, or the user to change the network connection method, which will lead to changes in the IP address. When we use the Internet, there are two types of IP addresses, one is a static IP address and the other is a dynamic IP address.

Because IP address resources are precious, most users use dynamic IP addresses to access the Internet. For example, computers that access the Internet through Modem, ISDN, ADSL, wired broadband, community broadband, etc., all use dynamic IP addresses every time. Temporarily assign an IP address when surfing the Internet.

Cause: The set option defaults to automatically obtain IP, so the IP address will change frequently. Solution: Taking win7 system as an example, first click to open the network option in the connected network location, and click "Open Network and Sharing Center" there.
