When this nameserver is reachable it will answer with an ip. If

www.xxxxx.com is unknown to the nameserver it will query some other nameserver. But in the end you'll get your ip.

Once this ip (lets say 123.123.123.111) is known there will be tried to establish a connection to 123.123.123.111:80 (this connection will be made by the standard routing procedure as can be viewed by typing route from a root shell.

Now the communication will be established, files will be transferd using the http protocol. So the nameserver simply translates www.xxxxx.com into an ip by quering its own databases or querying other databases.

1.4 Whooow that sounds very cool !!! So ? :p

Well suppose those seven steps take about 2 seconds (if you have a speedy connection and your ISP has a nameserver with almost no network traffic and if the ip is in the nameservers cache). So if this was an utopia it would take two seconds. So in these times it'll take a bit longer. In this tutorial we'll make something called 'a caching only nameserver'.

1.5 What is a caching only nameserver

Well, this is a special 'type' of nameserver. This is not intended to be the nameserver of your intranet. The only thing it does is to cache all names and ip's that are queried from the local network. The first time you query an ip, an other database has to be queried
