A message sent from one computer to one other computer

The portion of an IP address that defines a specific machine in a subnet

A number used in IP networks to identify the network on which a device or machine exists

Method of categorizing IP addresses in order to distribute them

The current version of the external routing protocol used on the Internet. Used for communications between Autonomous Systems

The value used in TCP/IP settings to divide the IP address of a host into its component parts: network ID and host ID

A command-line utility for Windows that displays the current TCP/IP configuration of the machine

The process of assigning IP addresses by manually typing them into client computers.

Protocol in which addresses consist of four sets of numbers, each number being a value between 0 and 255, using a period to separate the numbers. It is often called dotted decimal format

A state in which all routers within an area are up to date and their routing tables all match.

A way for a computer to receive IP information automatically from a server program.

Sometimes called the localhost, a reserved IP address used for internal testing: 127.0.0.1

A command-line utility for Linux servers and workstations that displays the current TCP/IP configuration of the machine

The organization responsible for assigning public IP addresses.

A router that acts as the default gateway for a number of client computers.

A protocol in the TCP/IP suite used with the command-line utility of the same name to determine the MAC address that corresponds to a particular IP address.

An agreement that governs the procedures used to exchange information between cooperating entities; usually includes how much information is to be sent, how often it is sent, how to recover from transmission errors, and who is to receive the information.

The addressing scheme of the IP protocol by which each machine on a TCP/IP network gets a unique IP address that identifies the machine. IP addresses group together sets of computers into logical networks, and equipment that understands

Taking a single class of IP addresses and chopping it into multiple smaller groups

A dynamic routing protocol that is more efficient than RIP, announcing and forwarding individual route changes as they appear, rather than sending the entire routing table

In a TCP/IP network, the IP address of the router that interconnects the LAN to a wider network, usually the Internet. This router’s IP address is part of the necessary TCP/IP configuration for communicating with multiple networks using IP.

A message sent from one computer to one other computer

A set of protocols that are commonly used together and operate at different levels of the OSI seven-layer model

A component of TCP/IP that allows computers to discover and receive an IP address from a DHCP server prior to booting the OS.

Where a packet should go when its destination address has a network ID not directly connected to the router
