Front

An IP address that is valid for use on public networks, such as the Internet.

Back

Public IP address

Front

IP addresses that can be used on a private network but not on the Internet. IEEE recommends the following IP address ranges for private use: 10.0.0.0 through 10.255.255.255; 172.16.0.0 through 172.31.255.255; and 192.168.0.0 through 192.168.255.255.

Private IP address

Front

IANA’s document that formally identified IP address ranges for private networks.

Back

RFC1918

Front

A message that is read by every node on a network.

Back

Broadcast

Front

Logically grouped network nodes that can communicate directly via broadcast transmissions. By default, switches and repeating devices, such as hubs, extend broadcast domains. Routers and other layer 3 devices separate broadcast domains.

Back

Broadcast domain

Front

An IP address (usually 127.0.0.1 or ::1) reserved for communicating from a node to itself, used mostly for troubleshooting purposes. The loopback address can be any IPv4 address in the range of 127.0.0.1 through 127.255.255.254. In IPv6, the loopback address is ::1.

Back

Loopback address

Front

The local computer. Localhost can refer to the local computer’s host name or to the loopback address for the local computer (usually 127.0.0.1 in IPv4 or ::1 in IPv6).

Back

Local host

Front

A service available on Windows computers that automatically assigns the computer’s NIC a link local IPv4 address in the range of 169.254.0.1 through 169.254.255.254.

Back

APIPA

Front

An IP addressing convention that alters the rules of classful IPv4 addressing to create subnets in a network.

Back

Classless addressing

Front

The process of segmenting a network into smaller networks that requires calculations of IP address ranges within a larger IP address range.
