Glossary
IP address
A unique address for a network component within a network based on the TCP/IP proto-
cols (e.g., LAN, Internet). On the Internet, domain names are usually assigned instead of IP
addresses. DNS assigns the corresponding IP address to the domain name.
The IPv4 IP address has four parts (decimal numbers between 0 and 255) separated by full
stops (e.g., 230.94.233.2).
The IP address is made up of the network number and the number of the network sub-
scriber (e.g., phone). Depending on the subnet mask, the first, second or third part makes
up the network number and the rest of the IP address addresses the network component.
The network number of all the components in any one network must be identical.
IP addresses can be assigned automatically with DHCP (dynamic IP addresses) or manually
(static IP addresses).
See also: DHCP.
IP pool range
Range of IP addresses that the DHCP server can use to assign dynamic IP addresses.
L
LAN
Local Area Network
Network with a restricted physical range. A LAN can be wireless (WLAN) and/or wired
(Ethernet).
LDAP
Lightweight Directory Access Protocol
Service for managing directories across a network.
LDAP is used to store and access information about individuals who are part of an organi-
sation (e.g., employees).
Local IP address
The local or private IP address is the address for a network component in the local network
(LAN). The network operator can assign any address he or she wants. Devices that act as a
link from a local network to the Internet (gateway or router) have a public and a private IP
address.
