To find your IP address at any time use the applet winipcfg which can be
run by clicking Start, Run, entering WINIPCFG in the box and then clicking
OK.  This will then tell you the IP address associated with each network
connection on your PC.  Note that if you are on a LAN this will only give
you your IP address and not that of any router between you and the
internet.  Perhaps the easiest way to establish the external facing IP
address of a router is to log on to the router.
