IP address 0.0.0.0?

[socalborn]

I'm just starting to learn about different network connections and I'm trying to find out why netstat would show the IP address 0.0.0.0 listening to my external IP address on a specific port and also listening to 127.0.0.1 and my ipv6 address? I've tried googling it but I'm just not understanding...

0.0.0.0 is all IPs bound on any interface. 127.0.0.1 is loopback.
