What route does the internet signal take?

First i assume that a DNS server is a privately owned server somewhere near your location and not something that your ISP provides?

So i thought the signal would take this path like this or so,

PC --> DNS server --> ISP --> "page your requesting"

then on the way back what path does it take, just the exact reverse?

Well no a DNS server is something that your service provider provides but you can also have your own DNS server as well (business networks use them)

Read this post I made from one of the other threads in this forum for a little more info on what DNS is for: http://www.vbforums.com/showpost.php...9&postcount=24

As for your actual question, what do you mean by "on the way back" ? When you connect to a web page or whatever you establish a connection with the server that is hosting the page and download the data straight from it, the server does not have to find a route to your PC because the connection is already established.

Router's typically use a variation of NAT to route between the internet and local intranet.

All routers are made to bridge the connection, even if it's between two intranets

Sorry that was route not router (typo) what route does the signal take from pc back to pc after requsting a page...doh

I answered that in my first post lol :)

when speaking of the internet, there typically isn't "one" route to and from a site. the route A packet takes in either direction may change from packet to packet.
