Real world usage of NETSTAT command?

[TechnoPro]

Just curious about how people use it as a tool... I use other command line networking tools extensively and want to learn more about this one. Thanks.

netstat -rn gives me routing information.
netstat -an shows me open connections and open ports.

That's generally about all I use it for.

netstat -an when I'm trying to figure out what connections are open. Netstat -an | grep -c :80 when trying to figure out how many instances of Apache are running (and whether that exceeds current limits.) It's useful.
