Components of a network with the help of identify a network tester can firmly be, what devices are within a network, or are connected to this, and if they meet their intended functions. The network tester is connected via a so-called Ethernet network input and through this then searches in search of useful and important information for the user. Initially the network tester on the search goes dynamic to DHCP Dynamic Host Configuration Protocol and looking after DNS name system. Then through the network tester network is actively seeking connected active units. When this operation is completed, network tester delivered the user information about name, IP addresses and MAC addresses of the units in the network.
Because the network tester with a monitoring function is equipped, he recognises even units that the areas on the network of other addresses access and within its data or messages send. Depending on examining Network tester then also the addresses area these other units and passes the collected information to the user. Increasing the network tester to prompt a survey of all units concerned and recognize on the basis of the found results, kind of it’s units and which services are active. It is not necessary that a computer on your network is connected to be able to work with the network tester. He works independently and can be applied directly. This is one of the major differences between a network tester and a program to the network monitoring, which must run on a PC. Usually, the analysis and diagnosis of the network tester takes 10 seconds or even less. After 10 seconds the network tester is already on all the components that are in the network, able the user to show and he also automatically sorts them into different groups, which makes it easier to track and makes the information more accessible.
