Term Definition
iNAT™ (Intelligent Network Address Translation) Nomadix’ iNAT™ feature creates an intelligent
mapping of IP addresses and their associated VPN tunnels allowing multiple tunnels to
be established to the same VPN server—creating a seamless connection for all the users
at the public-access location.
infrastructure
mode An 802.11x networking framework in which devices communicate with each other by
first going through an Access Point (AP). In infrastructure mode, wireless devices can
communicate with each other or can communicate with a wired network. When one AP
is connected to a wired network and a set of wireless stations it is referred to as a Basic
Service Set (BSS). An Extended Service Set (ESS) is a set of two or more BSSs that form a
single subnetwork. Most corporate wireless LANs operate in infrastructure mode
because they require access to the wired LAN in order to use services such as file
servers or printers. See also, ad-hoc mode.
Internet Originally developed by the U.S. Defense Department, the Internet is now a global
collection of networks that transfer information between each other using the Internet
Protocol (IP). Additionally, the Internet carries the hypertext system commonly known as
the World Wide Web. See also Hypertext and Internet Protocol.
Internet Protocol The global standard used to regulate data transmissions between computers and the
Internet. Data is broken up into packets which are then sent over the network. By using
IP addressing, Internet Protocol ensures that the data reaches its destination, even
though different packets may pass through different networks to get to the same
location. See also, Internet and IP Address.
Internet Service
Provider The agency that provides you with access to the Internet. Your Internet Service Provider
(ISP) may be a large commercial organization (for example, America Online) or, if you
access the Internet via your employer, then your employer is your Internet Service
Provider. See also, Internet.
Intranet A network confined to a single organization (but not necessarily a single site). Usually
thought of as a corporate mini Internet.
IP See Internet Protocol.
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, Domain Name,
Dynamic IP Address, Internet Protocol, 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, Dynamic IP Address, IP
Address, and Static IP Address.
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).
