To use the port number and the IP address under which it is in network it is necessary to define to what what port the IP address corresponds at the moment. Each of them will have special flags which will be told the user about numbers of identifiers of processes of Windows assigned to them.
It is required to you
- The configured and established network connection.
Instruction
1. The algorithm of definition the IP address of port varies depending on what devices and resources are used at the moment. For the user computer which is in Network having access to certain resources, the algorithm will be the following: - Open the command line. For this purpose enter the Start menu, click on the Execute point, and by means of the keyboard enter the cmd command. This action will open a window of black color, a window of the command line. - Enter into a window of the command line by means of the keyboard the ping_sayt_servera command, a sayt_server — the resource address in Network. Click Enter that the command was executed. In a window of the command line the table with the IP addresses and resources corresponding to them will open.
2. If the port is used by a certain device, then it will be required to perform a number of simple operations for definition of the IP address of this device: - Activate the device which IP address of port is supposed to be defined. Open the command line actions, described above — enter the Start menu, click on the Execute point, and keys of the keyboard enter cmd. Click Enter that the command was executed. - Enter by means of the keyboard into a window of the command line the netstate command, and click Enter for its execution. In a window of the command line each connection activated by devices and identifiers of ports opposite to them will be displayed.
3. Instead of the last command it is possible to use the command NETSTAT-AON | MORE also. This command will display in the right part of a window of the command line the PID list, process identifiers. On an illustration it is possible to see that the PID device having IP address 0.0.0.0:80, that is attributed to the eightieth port, it will be equal to 4708.
4. Now the user can just load a task manager — quite possibly that use of the option "Show Processes of Each User" will be required, and PID will be found in a list of applications — it is possible to determine by it what application directs the device with the set IP.
5. Use of data on the IP addresses of devices can help to maintain anonymity in network and to protect the operating system. It is impossible to refuse its use as IP is necessary for routing of information. At the same time it is possible to configure connection of devices and applications via the proxy-server which will receive and send data as if on its own behalf. However their vast majority specifies the address of end users in the office x-forwarded-for field.
