DNS
Domain Name System
DNS permits the assignment of IP addresses to PC or domain names, which are easier to
remember. A DNS server must administer this information for each LAN with an Internet
connection. As soon as a page on the Internet is called up, the browser obtains the cor-
responding 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 DNS server. This in turn knows all
the addresses of the PCs in the local network and the next higher DNS server, which
again knows addresses in its network and that of higher DNS servers.

means that the IP address of a network component can change with every login or at
certain intervals.
