Default Router
|
Default Gateway, also known as the default routers
(Wendell, 2013 p. 105) In computer networking, a default gateway is the device that passes traffic from the local subnet to devices on other subnets. The default gateway often connects a local network to the Internet, although internal gateways for local networks also exist. (Mitchell) |

|
Routing Table
|
A list of routes in a router, with each route listing the destination subnet and mask, the router interface out which to forward packets destined to that subnet, and as needed, the next-hop router's IP address.
(Wendell, 2013 Sect. Glossary) |
|
|
IP Network
|
Classful IP network
An IPv4 Class A, B, or C, network: called a classful network because these networks are defined by the class rules for IPv4 addressing. (Wendell, 2013 Sect. Glossary) |
|
|
IP Subnet
|
Subdivisions of the Class A,B, or C network, as configured by a network administrator. Subnets allow a single Class A,B, or C network to be used instead of multiple networks, and stillallow for a large number of groups of IP addresses, as required for efficient IP routing.
(Wendell, 2013 Sect. Glossary) |
|
|
IP Packet
|
An IP header, followed by the data encapsulated after the IP header, but specifically not including any headers and trailers for layers below the network layer.
(Wendell, 2013 Sect. Glossary) |
|
|
Routing
|
Hosts use software to choose where to send IP packets, often times a nearby router. These routes make choices of where to send the IP packets next. Together, the host and routers make choices of where to send the IP packets to the correct destination
(Wendell, 2013 p. 92) |
|
|
Protocol
|
A set of logical rules that devices must follow to communicate.
(Wendell, 2013 p.19) |
|
|
DDN
|
Dotted-Decimal Notation
The formula used for IPv4 addresses, in which four decimal values are used separated by periods (dots) (Wendell, 2013 Sect. Glossary) |
|
|
IPv4 Address
|
IP version 4
In IP version 4 (IPv4), a 32-bit address assigned to hosts using TCP/IP. Each address consists of a network number, and an optional subnetwork number, and a host number. The network and subnetwork numbers together are used for routing, and the host number is used to address as individual host within the network or subnet. (Wendell, 2013 Sect. Glossary) |
|
|
Unicast IP address
|
An IP address that represents a single inteface. In IPv4, these adresses come from the Class A, B, C ranges.
(Wendell, 2013 Sect. Glossary) |
|
|
Subnetting
|
The process of subdividing a Class A, B, or C network into smaller groups called subnets
(Wendell, 2013 Sect. Glossary) |
|
|
Host Name
|
The alphanumeric name of an IP host.
(Wendell, 2013 Sect. Glossary) |
|
|
DNS
|
Domain Name System
An application layer protocol used throughout the Internet for translating host names into their associated IP address. (Wendell, 2013 Sect. Glossary) |
|
|
ARP
|
Address Resolution Protocol
An internet protocol used to map an IP address to a MAC address, as kept in memory by hosts and routers (Wendell, 2013 Sect. Glossary) |
|
|
Ping
|
Packet Internet Groper
An Internet Control Message Protocol (ICMP) echo message and its reply; ping often is used in IP networks to test the reach ability of a network device. (Wendell, 2013 Sect. Glossary) |
