Hello, this is my first post on the Unix forums. This is something that's been bothering me for a while, is there any particular UNIX/Linux application that will allow you to see you external IP address? ( The address beyond your router )

Thank you in advance, I could not find a solution to this using google. Many of the solutions I found pointed me to websites that simply gave you your external ip, but i thought it would be nice to do this from within the comfort of the terminal.
