The web site www.google.it is translated into 216.239.39.104. In fact if we write this numbers in the address line of our browser, we are redirected the web site google.it
This numbers are the IP - Internet Protocol - address.

Each letter from A to M identifies a single IP address. They are situated in more than 35 countries ( more than 84 locations ), most of them outside the USA. Not all the exact locations of the root servers are known because of security reasons.
This is how it works:
We want to go to www.symantec.com
1)Our computer asks our ISP ( Internet Service Provider - that is the company which provides us the Internet connection ) DNS server what is the number (IP) of this web site. If this server knows it, our computer will be connected with the computer where this site is.
2)If our ISP DNS server has not that information,it will ask other DNS servers until it finds the IP number which it is looking for. After that, our computer will be connected with the computer where this site is.
3)If it is not possible to find that address - wrong number or the web site does not exist - our browser will not be able to show us that web site.
DNS propagation: it is the process which inserts a website IP number into the DNS server around the world. It may take up to 72 hours. This is why a new website is not visible on the Internet before that period of time.
