On messenger though, not even corporate users use a proxy, even though Yahoo
offer their employees the "socks.yahoo.com" network. This is because using a
proxy over messenger really does affect the whole operation of refresh ping
times on your messenger list status of users going on and offline etc. With
your method of just getting someone to view a file hosted on a webserver
wouldn't work if you were trying to hack Yahoo, because all employees, for
the internet explorer, firefox browser, they all use the socks, socks1,
socks2,socks3 and so on, so you would be in a highly unlikely position to
actually getting their actual hostname. On messenger its different, the
social psychology of corporate users is that they believe they are in a
false sense of security, wrapped in cotton wool, because by adding you to
their messenger list, you've already got by that "trust" element, and as
soon as you do get on a messenger list of a corporate user then you have
more or less suceeded in completing the most sicnificant part of the attack
to steal corporate data from an individual within a major dot-com. If you
want a non-proxy IP from a corporate user, messenger is the application they
very rarely use with their corporate proxy, trust me, I know about this
stuff.

If you have control over a webserver, send the friend a link to an invalid
image on that webserver and tell them to click on it.  Once they've clicked
the link check your server logs for that invalid image and you should have
their IP address (unless they're using a proxy like mentioned before).  You
can also do this with an email if your "victim's" email client is configured
to automatically render images when an email is opened.  This technique has
been referred to as a "web bug".
