In windows port status command

Netstat -a

What is the meaning of *:* in foreign address?

Notice that all of the ones that show up as *:* are for the UDP ports.

TCP ports and UDP ports are different in that TCP ports can keep an open connection and therefore will show a state - such as listening, closed_wait, established, etc.

UDP ports do not work this way. They make the connection, transfer data and then close. You will not see a listening or waiting connection. You will only see that a connection has been made.
