DNS

Domain Name System

DNS permits the assignment of IP addresses to computers or Domain names that 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 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

all the addresses of the PCs in the local network and the superordinate name servers,

which again know addresses of the next superordinate name servers.

DNS server

See DNS

Domain name

The domain name is the reference to one or more Web servers on the Internet. The

domain name is mapped via the DNS service to the corresponding IP address.

DoS attack

Denial of Service

A DoS attack is a particular form of hacker attack directed at computers and networks

with a connection to the Internet. The aim is not so much to steal data but to paralyse

the computer or network so severely that the network resources are no longer available.

A typical hacker attack involves making a remote computer announce that it is acting

for the paralysed computer, for example, and receive the data intended for you.

DSL

Digital Subscriber Line

DSL is a data transfer technique in which a connection to the Internet can be run at high

speed over normal telephone lines. A DSL connection is provided by an Internet service

provider. It requires a DSL modem.

Dynamic IP address

A dynamic IP address is assigned to a network component automatically by DHCP. This

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

certain intervals.
