Classic vro configuration completely solves the problem of vro IP address conflict

Reasonable DHCP parameter settings can completely solve the problem of IP address conflict between routers. In some wireless networks, due to the large number of clients, in order to facilitate the management of these machines, many administrators use the DHCP service provided by the wireless router to Configure TCP/IP parameters for the client, such as the router IP address, gateway address, and DNS server.

However, in your wireless network, some computers must manually specify the TCP/IP parameter configuration. In this case, the dynamic router IP Address Provided by the DHCP server and the manually specified static IP address coexist, if you do not properly configure the parameters of the DHCP server in the wireless router, the IP address of the router may conflict.

How does a conflict occur?

For example, if you manage a wireless network with 50 computers, five of them use manual static IP addresses for special purposes. The IP address range is "192.168.1.10 ~ 192.168.1.14 ". The other 45 computers obtain parameters such as IP addresses through the DHCP service of the wireless router. However, if the "address pool" parameter of the DHCP service in your wireless router is set improperly and contains the IP address segments used by the above five computers, a vro IP address conflict may occur.

The cause of IP address conflict is very simple. For example, if computer A with the static IP Address "192.168.1.11" is not started, when A computer B in the wireless network requests an IP address from the DHCP server of the wireless router, the DHCP server finds that the IP address "192.168.1.11" is currently idle and is not used by any computer. Therefore, it is very likely that the IP address will be allocated to the computer B requesting the IP address. When computer A starts and goes online, it will find other computers using the IP address "192.168.1.11", so there will be IP address conflicts.

Set DHCP parameters properly

Knowing how a vro IP address conflict occurs in a wireless network is easy to prevent. As long as you properly set the "address pool" parameter in the DHCP server. You must be clear about the IP address segments occupied by computers using static IP addresses. To avoid IP address conflicts, When configuring the IP address pool parameter of the DHCP server, be sure to exclude these IP segments occupied by static router IP addresses.

Here we take wireless networks as an example (). computers using static IP addresses occupy "192.168.1.10 ~ The IP address segment 192.168.1.14. Therefore, this IP address segment must be excluded when setting the "address pool" parameter to prevent conflict. Set the "address pool" parameter to "192.168.1.15 ~ 192.168.1.60 ", which not only meets the needs of 45 Dynamic IP address clients, but also prevents conflicts between router IP addresses.
