The -l just lists ports that are in the act of listening, whereas active connections are listed separately. For instance, if you have another computer on your home network (B), ssh from B to A. Then on A, list all the TCP connections with a netstat -at. The listening ports (including ssh) will show a foreign address of as above, and listed separately below in the active connections you'll see your ssh connection from B to A.
OK, but a potential connection (i.e. listenting) from Local address 0.0.0.0:[arbitrary port number] to foreign address 0.0.0.0:[arbitrary port number] represents a possible connection between what IP's? So far, I have to assume that it is either any IP or no IP.
0.0.0.0 = any
On TCP/IP networking, 0 as any octet of an IP is, for all purposes,
a universal globing. That's why I hate people who set their LANs to
use 192.168.0.x as their IPs...it drives me crazy, even if it's
valid :)
