IP
short for Internet Protocol
The IP Internet Protocol is the most important basic protocol
for the control of data exchange in local networks and in the
Internet. The Internet protocol works without a connection; in
other words, data packets are transmitted from the sender to
the recipient without previous consultation. The addresses of
the recipient and the sender in the data packets are given as
IP addresses.
IP address
In IP-based networks, for instance in the Internet and local
networks, all connected devices are addressed via their IP ad-
dresses. So that data packets are sure to be delivered to the
right address, each IP address may be assigned only once
within the Internet or a local IP network.
IPv6 addresses are structured differently from IPv4 address-
es. IP addresses can be written in decimal, octal or hexadeci-
mal format.
IP masquerading
IP masquerading is a technique used within IPv4 networks.
With IP masquerading a computer or LAN can be protected
from unauthorized connection requests from the Internet.
Masquerading works by converting the IP addresses used in a
network to one public IP address. From the outside it appears
as if all requests are sent from a single computer.
IP network
A network in which data exchange takes place on the basis of
the Internet Protocol (IP) is called an IP network.
IPv4
short for Internet Protocol version 4
IPv4 is currently the conventional Internet protocol.
