What does "::" denote in windows netstat results?

Question

I'm trying to understand on which interfaces a TCP port is open

Using windows netstat command I get result like :

TCP    [::]:10000             MyMachineName:0               LISTENING

What does the symbol "::" mean here ? for rest of the ports it shows local loop-back or LAN machine name properly or even 0.0.0.0 in some cases.

It's IPv6 to indicate the use of any local address. I.e. equivalent to the IPv4 0.0.0.0.

Typically an application would bind to this address when it doesn't mind which interface to use, or to listen on any of the IP interfaces.

In IPv6, :: can be a replacement for multiple fields of zero... Read more here:
