Hello,
I am wondering if the DNS system is not a bit inefficient if we want to get a resource on the internet.
If for instance you want to go to the "epfl.ch" website, what happens is that the browser first translate "epfl.ch" to an IP address (using the DNS servers) and then does a request to that webserver for the web page.
Coudn't those requests be merged, so that instead of doing two strips, we would only need to do one ?
So when we type "epfl.ch" in the web browser, it would use the DNS servers to find the authoritative server of epfl, and that authoritative server instead of replying with the IP address, it would directly reply with the web page ?
