Basics of networking

To display the connected connections of our computer to various servers in Windows we can use Wireshark, through which we were able to check everything that passes through our network card, and also use the NETSTAT command in the Windows console. Once entered, we can keep track of what active connections we have. The output of this command shows the type of transport layer protocol used for the connection, the socket of our computer, i.e. the IP address with the port number, the socket of the server to which we are connected, and the connection status.

The programmes can be called with various arguments, and a list and description of these will be displayed when the netstat /help command is entered.

To check which services our computer is connected to, we may run the netstat -f command and copy the domain name (PPM -> Tag -> Select Domain Name -> CTRL + C or PPM -> Copy).

We can see the owner of the domain through whois.domaintools.com and its search engine.
