what i'm saying is, you could traceroute to say yahoo, but which of  
the hops is the proxy? you have no way of knowing, except it's  
probaby the next hop after your default router.  but even knowing  
that won't help you avoid it....unless your network guys are  
completely clueless...that segment should have one and only one way  
out, that leads to the router that forwards to the proxy
