 connection. As soon as a page on the Internet is called up, the browser 
obtains the corresponding IP address from the DNS server so that it can establish the 
connection.
On the Internet, the assignment of domain names to IP addresses follows a hierarchical 
system. A local PC only knows the address of the local name server. This in turn knows
