If I enter the following command in CMD prompt...
netstat -ano
I get a list of active connections as expected. What confuses me is that there are many different formats for my "Local Address"...
Proto Local Address Foreign Address State PID
TCP 0.0.0.0:135 0.0.0.0:0 LISTENING 656
TCP 208.80.154.224:13 0.0.0.0:0 LISTENING 4
TCP 127.0.0.1:2559 0.0.0.0:0 LISTENING 8628
TCP [::]:135 [::]:0 LISTENING 656
UDP [::1]:1900 *:* 4512
For a particular connection, what determines which format is used for my "Local Address"? i.e. why is 0.0.0.0 displayed for some connections and [::] displayed for other connections, and so on?
