> >Checking the path to my DNS servers tells you NOTHING about the >path to my hosts. Right. But your situation is not the one being looked at, as you don't have geograpically distributed web servers. I believe for that situation 3DNS, et. al., can work. Once the client's DNS request has worked its way over to the primary DNS for the distributed web-servers, 3DNS has each of the other 3DNS boxes (located adjacent to the other distributed servers) ping the *clients* primary DNS. 3DNS then returns the URL for the web-server whose 3DNS machine is 'closest' (fewest hops) to the clients DNS machine. Thus, for example, clients in Asia can get to a server in Asia. I think that's the gist of it, if not the specifics...
