TCP is a connection-oriented reliable protocol for transporting data between networked computers. It is defined in IETF RFC 793.

The following example displays endpoint information for active TCP connections.

Public Shared Sub GetTcpConnections() 
    Dim properties As IPGlobalProperties = IPGlobalProperties.GetIPGlobalProperties()
    Dim connections As TcpConnectionInformation() = properties.GetActiveTcpConnections()
    
    Dim t As TcpConnectionInformation
    For Each t In  connections
        Console.Write("Local endpoint: {0} ", t.LocalEndPoint.Address)
        Console.Write("Remote endpoint: {0} ", t.RemoteEndPoint.Address)
        Console.WriteLine("{0}", t.State)
    Next t

End Sub 'GetTcpConnections
