IP address conflict is a very common network problem, computer An originally used IPA, I do not know what happened, changed to computer B IPB, then the direct result is that computer An and B can not access the Internet, this kind of accident is really a common accident, but as soon as it comes out, it will not be able to surf the Internet. If there is no suitable detection tool, IT or network management will have more and more headaches for such accidents.

1. It is necessary to have a good detection tool so that network problems can be preliminarily identified. This function is available in all our WFilter products and all WSG products. A conflict between IP and MAC addresses has been detected, and the specific situation is correct.

two。 The first step is testing, testing is just testing, so how to solve the problem of IP conflict. The easiest way is to change the IP back, but this is a temporary cure rather than a permanent cure. After a period of time, if there is a fast hand, there is still a conflict, and then the network is still cut off. If you want to solve the problem at the root, the easiest way is to bind IP and MAC, which can be configured either on routing or on core switches. But the configuration effect is also uneven. Compared with rub routes, although IP and MAC binding are set, it is impossible to disable IP other than binding. In this way, the new devices will lead to IP conflicts, and manually set the IP, and bypass the binding, then the conflict will conflict again, resulting in endless troubles and network management misery. Most of the routes in the market are like this, although bound, temporary cure is also a permanent cure, but can not get to the root, but the follow-up troubles continue. And no route can configure IP and MAC bindings across network segments. If it is configured on the switch, then first of all, there must be a core switch, and this configuration also has to find someone else, ah, a switch technician to serve, which is too troublesome.

3. Bind IP to MAC, whether it is a single IP address range or multiple IP address ranges. No matter it is an external device or you want to change the IP manually, there is no way to achieve the true IP fixation. In this way, the world is at peace. (note: this feature is available only with our WFilter-NGF and WSG products)

4. IP conflict resolution is not perfect, but it is definitely at TOP level. Once set up, there is no way for people in the LAN to manually change the IP or change the MAC themselves, or to have a new IP in the new device, and there is no way to bypass the management. From then on, the binding of IP and MAC for network management is once and for all.
