IEEE 802.16
for WiMAX. Similarly to other standards in the 802 series
, 802.11 WLAN), the WiMAX standard is one of the standards for
networks. The standard has progressed in accordance with new developments; there
are currently two main versions:
IEEE 802.16-2004: WiMAX, which specifies the secure location for connection part-
ners.
IEEE 802.16e-2005: Mobile WiMAX, which enables wireless cells to be exchanged
during data transmission.

rotocol. The protocol is responsible for addressing of subscribers in a network
using IP addresses, and routes data from the sender to the recipient. In doing so, it
decides on the way in which data packets will be forwarded between sender and recip-
ient.
IP address
An IP address is the unique network-wide address of a network component in a net-
work based on the
protocol (e.g. in a local network or on the Internet). The IP
address consists of four parts (each of up to three-figure strings of digits from 0–255)
that are separated from one another by full stops (e.g. 192.168.2.1). The IP address is
made up of the network number and the number of the network component. Depending
on the
, one, two or three parts form the network number, the remainder
form the network component number. You can find out the IP address of your PC using
the
ipconfig
command.
There are two different types of IP address:
Private IP address
:
IP address of a network component within a local network.
Public IP address
:
IP address that uses a network component for accessing the Internet.
IP addresses can be assigned manually or automatically:
Static IP address
:
The IP address is manually assigned to a network component and never changes.
Dynamic IP address
:
The IP address is assigned to the network component by a DHCP server. The IP
address of this network component can change each time it registers with a network
or at specific time intervals.
On the Internet, domain names are normally used instead of the IP addresses. DNS is
used to assign domain names to IP addresses.
