IP Address
The numeric address of a device, in the format used on the Internet. The actual numeric value takes the form of a 32-
bit binary number broken up into four 8-bit groups, with each group separated by a period (for example, 198.43.7.85).
To make it easier for the user, the IP address is mapped to a meaningful domain name. IP addresses can be static
(permanent) or dynamic (assigned each time you connect). See also,

, and
Static IP Address
.
IP Address Translation
Nomadix Gateways use adaptive configuration technology which can accommodate all network configurations,
including dynamic and static IP address assignments. This enables it to solve IP addressing problems in environments
where the service provider does not have control over the subscriber’s network settings. Whenever a subscriber logs
on, your Nomadix Gateway automatically translates their computer’s network settings to provide them with seamless
access to the broadband network. Subscribers no longer need to alter their computer’s settings. See also,

ISDN
(Integrated Services Digital Network) An international communications standard for sending voice, video, and data
over digital telephone lines or normal telephone wires. ISDN supports data transfer rates of 64 Kbps (64,000 bits per
second).

LAWN
(Local Area Wireless Network) A type of Local Area Network that uses high-frequency radio waves rather than wires
to communicate between nodes. Also referred to as
WLAN . See also, Node .
LDAP
(Lightweight Directory Access Protocol) Directories containing information such as names, phone numbers, and
addresses are often stored on a variety of incompatible systems. LDAP provides a simple protocol that allows you to
access and search these disparate directories over the Internet. LDAP is commonly used for online billing applications.
MAC Address
(Media Access Control) The hardware address that uniquely identifies each node of a network. In
IEEE
802 networks,
the Data Link Control (DLC) layer of the OSI Reference Model is divided into two sub layers – the Logical Link
Control (LLC) layer and the Media Access Control (MAC) layer. The MAC layer interfaces directly with the network
media. Consequently, each type of network media requires a different MAC layer. On networks that do not conform to
the IEEE 802 standards but do conform to the OSI Reference Model, the node address is called the Data Link Control
(DLC) address.
Mbps
(Megabits per second) A standard measure for data transmission speeds (for example, the rate at which information
travels over the Internet). 1 Mbps denotes one million bits per second. Several factors can influence how quickly data
travels, including modem speed, bandwidth capacity, and Internet traffic levels at the time of transmission. Not to be
confused with MegaBytes per second (MBps). See also,
Throughput
.
MIB
(Management Information Base) A set of parameters an SNMP management station can query or establish in the
SNMP agent of a network device (for example, a router). Standard minimal MIBs have been defined, and vendors
often have their own private enterprise MIBs. In theory, any SNMP manager can talk to any SNMP agent with a
properly defined MIB. See also,
