retrieve router's IP number
I have a Linux (Red Hat) server running behind a router. My "world" IP number is dynamic, so I'd like to be able to retrieve it using a script. Traceroute, ping, and dig do not give me the info I need. ifconfig gives me the private IP number. I am currently using
Code:
lynx -dump www.whatismyip.com and capturing the output, but I don't like relying on an outside source if avoidable. (And I don't like hammering their site.) Does anyone know of any Linux command that would return my world IP?

you missed the most important part here what router are you using? as if it was a cisco you would right a script to telnet to the router and do a [sh ip int brie | i interface ] then grep the address line. also do a man on trace and see if there are extended commands as cisco routers can trace a full async path with return route in that case you would grep the last public address.
