How to query a valid IP address quickly in a local area network? Usually in the daily use of computers in order to let workstations smoothly through the LAN Internet, we often need to configure a valid IP address, but what is the local area network IP address is not used? This article now for you to sum up a few users quickly assigned to the workstation IP address of the trick, I hope these skills can help you to effectively manage the LAN network.

As you know, if a workstation in a local area network is online, we should be able to ping the workstation's IP address properly when using ping, and conversely, if we can ping a normal IP address using ping, That means the IP address is already occupied by a workstation in the LAN, so ping the IP address of each workstation in the LAN, and according to the test result of Ping, we can quickly find the valid and available IP address in the local area network, when assigning this address to the new workstation, I believe that there will be no more address conflict failure.

For example, if we want to see if the 10.172.168.2 address is already occupied, just click the Start, Run menu command in the local workstation system desktop, and then enter the string command "cmd" in the Pop-up System Run dialog box, and then click OK. Switch the system to the MS-DOS command line state.

At the MS-DOS command line prompt, enter the string command "Ping 10.172.168.2", and then click Enter To see if the 10.172.168.2 address can be ping, if found that the address can be ping, it means that the 10.172.168.2 address has been preempted by other workstations, at this point, we only have to test other IP addresses one by one, until we find the IP address without ping.

It is noteworthy that this method of searching for a valid IP address is not very accurate, because in some workstations that have installed and enabled firewall programs, the IP addresses they use are not generally able to ping the IP addresses they use because they are protected by firewalls. So one of those IP addresses that cannot be ping is not necessarily an idle, valid IP address. This method is only suitable for some small LAN, while the LAN workstation is best not to install the firewall program.
