The Internet Group Multicast Protocol is a protocol that provides the means for a host to in-
form its attached router that an application running wants to join a specific multicast group.
The Internet Protocol is a method transmitting data over a network. Data to be sent is divided
into individual and completely independent "packets." Each computer (or host) on the Internet
has at least one address that uniquely identifies it from all others, and each data packet
contains both the sender's address and the receiver's address. The Internet Protocol ensures
that the data packets all arrive at the intended address. As IP is a connectionless protocol,
(which means that there is no established connection between the communication end-
points) packets can be sent via different routes and do not need to arrive at the destination
in the correct order. Once the data packets have arrived at the correct destination, another
protocol, Transmission Control Protocol (TCP) puts them in the right order.
An IP address is simply an address on an IP network used by a computer/device connected to
that network. IP addresses allow all the connected computers/devices to find each other and
to pass data back and forth. To avoid conflicts, each IP address on any given network must
be unique. An IP address can be assigned as fixed, so that it does not change, or it can be
assigned dynamically (and automatically) by DHCP. An IP address consists of four groups (or
quads) of decimal digits separated by periods, e.g. 130.5.5.25. Different parts of the address
represent different things. One part represent the network number or address, and other part
represents the local machine address.
IPv6 provides an identification and location system for computers on networks and routes
that traffic across the Internet.
The Layer 2 Tunneling Protocol is used to support VPNs or as part of the delivery of services
by ISPs.
A communication infrastructure that supports data and resource sharing within a small area
that is completely contained on the premises of a single owner.
Standardized data link layer address that is required for every port or device that connects
to a LAN. Other devices in the network use these addresses to locate specific ports in the
network and to create and update routing tables and data structures. MAC addresses are 6
bytes long and are controlled by the IEEE.
Mac Address Filtering permits and denies network access to specific devices based on a de-
vice's MAC address.
A Message-Digest algorithm is a widely used cryptographic hash function producing a 128-bit
(16-byte) hash value, typically expressed in text format as a 32 digit hexadecimal number.
