To display active TCP or UDP connections, you can use the command netstat -an
in the command prompt or terminal. This command shows all active connections and listening ports, along with their respective IP addresses and port numbers. For a more detailed view, you can use ss -tuln
on Linux systems, which provides similar information with additional options for filtering.
Active TCP connections
netstat /all will show you all active connections
The command netstat provides information about network connections, routing tables, interface statistics, masquerade connections, and multicast memberships. It can show all active network connections, listening ports, and the state of the connections. Additionally, it displays information about routing tables, interface statistics such as packets transmitted and received, and network protocol information.
netstat----------most useful and very versatile for finding connection to and from the host. you can find out all the mulitcast groups (network) subscribed by this host by issuing "netstat -g"netstat -nap | grep port will display process id of application which is using that portnetstat -a will display all connections including tcp and udpnetstat --tcp will display only tcp connectionnetstat --udp will display only udp connectionnetstat -g will display all multicast network subscribed by this host.
Netstat reports on the common tcp/ip protocols, including (but not limited to) TCP, UDP, ICMP, socket connections.

You display any active routes
Open command prompt and type netstatThis will show all ports in use and all ingoing\outgoing connections along with the connection type. TCP, UDP
Depending on what kind of server it is, connections can be very transient. The 'netstat -nat' command should print out a list of current TCP connections.
Nbtstat stands for NetBIOS over TCP/IP Statistics. It is a command-line utility used in Windows to display protocol statistics and current TCP/IP connections that use NetBIOS over TCP/IP. Nbtstat can help troubleshoot network issues related to NetBIOS name resolution, displaying the name table of a remote computer and allowing users to clear or refresh the local cache of NetBIOS names.
There are N nodes in the overlay network. There are N(N-1)/2 edges.
Ipconfig is used to show all current TCP/IP network configurations values and connections in Microsoft Windows. It is a command line tool.
