Resolution of IP address conflict Fault in wireless network

In some wireless networks, because of the large number of clients, to facilitate the management of these machines, many administrators use the DHCP service provided by the wireless router to provide clients with TCP/IP parameter configuration, such as IP address, gateway address and DNS server. However, if your wireless network, some computers must manually specify the TCP/IP parameter configuration, when the DHCP server to provide dynamic IP address and manually designated static IP address coexistence, if you do not reasonably configure the wireless router in the parameters of the DHCP server, it will be very easy to cause IP address conflicts.

How does conflict arise?

such as the author of a wireless network management, there are 50 computers, of which 5 computers due to special needs, the use of manual setting of static IP address, the use of the IP address segment is "192.168.1.10~192.168.1.14", The other 45 computers obtain parameter information such as IP address through the DHCP service of the wireless router. However, if you have a wireless router in the DHCP service "address pool" parameter set unreasonable, contains more than 5 computers use the IP address segment, it is possible to generate IP address conflicts.

The reason for the IP address conflict is very simple, such as Computer A with static IP address "192.168.1.11" is not powered on, and when a computer B in the wireless network requests an IP address from a wireless router's DHCP server, the DHCP server discovers "192.168.1.11" This IP address is currently idle and is not available to any computer, and it is likely that this IP address will be assigned to the computer B where the IP address is applied. When computer a boot up on the line, you will find that there are other computers using the "192.168.1.11" This IP address, it will produce IP address conflicts.

Reasonably set DHCP parameters

Know how the IP address conflict is generated in the wireless network, prevent this kind of occurrence is very simple, as long as you reasonably set the DHCP server "address pool" parameters. You want to know clearly, the static IP address mode of the computer to occupy the IP address segments, in order to avoid IP address conflicts, when configuring the DHCP server's "address pool" parameters, be sure to exclude the static IP address occupied by these address segments. (Computer science)

Here or the author's wireless network as an example (pictured), the use of static IP address of the computer to occupy the "192.168.1.10~192.168.1.14" This IP address section, so set the "address pool" parameter must exclude this IP address section to prevent the emergence of conflict, such as the author will be "address pool "The parameter is set to" 192.168.1.15~192.168.1.60 ", which satisfies the needs of 45 dynamic IP address clients and prevents the generation of IP address conflicts.
