IANA	The Internet Numbering Address Authority (IANA) is an organization under the Internet Architecture
	Board (IAB) of the Internet Society that oversees IP address allocation. It is under a contract from the
	U.S. government.
ICMP	Internet Control Message Protocol is a protocol used for error, problem, and informational messages
	sent between IP hosts and gateways. ICMP messages are processed by the IP software and are not
	usually apparent to the end-user.
ICSA	The International Computer Security Association is the security industry’s main source of research,
	intelligence, and product certification.
IEEE	The Institute of Electrical and Electronics Engineers, Inc. (http://www.ieee.org) is an organization that
	produces standards, technical papers, and symposiums for the electrical and electronic industries and
	is accredited by ANSI.
IEEE 802.11b	IEEE wireless network standards.
IEEE 802.11g
IEEE 802.3	See Ethernet.
IETF	The Internet Engineering Task Force (http://www.ietf.org) is an open international community of
	network designers, operators, vendors, and researchers to develop and maintain Internet architecture.
	Technical working groups issue working documents called Internet-Drafts. The IETF publishes review
	versions of the drafts called requests for comments (RFCs).
IGMP	Internet Group Membership Protocol the Internet multicasting standard. IGMP establishes and
	maintains a database of group multicast addresses and interfaces to which a multicast router forwards
	multicast packets. IGMP runs between multicast hosts and their immediately-neighboring multicast
	routers.
IGMP spoofing	A process where a router acts as an IGMP querier for multicast hosts and an IGMP host to a multicast
	router.
impedance	The total opposition to ac electron current flow within a device. Impedance is typically 75 ohms for
	coax cable and other CATV components.
impulse noise	Noise of very short in duration, typically of the order of 10 microseconds. It is caused by electrical
	transients such as voltage spikes, electric motors turning on, and lightning or switching equipment that
	bleed over to the cable.
ingress noise	Noise typically caused by discrete frequencies picked up by the cable plant from radio broadcasts or
	an improperly grounded or shielded home appliance such as a hair dryer. Ingress is the major source
	of cable system noise.
Internet	A worldwide collection of interconnected networks using TCP/IP.
Internetwork	A collection of interconnected networks allowing communication between all devices connected to any
	network in the collection.
IP	Internet Protocol is a set of standards that enable different types of computers to communicate with
	one another and exchange data through the Internet. IP provides the appearance of a single,
	seamless communication system and makes the Internet a virtual network.
