TERM DEFINITION
domain name A unique name, such as motorola.com, that maps to an IP address.
Domain names are typically much easier to remember than are IP
addresses.
dotted-decimal format A method of representing an IP address or subnet mask using four
decimal numbers called octets. Each octet represents eight bits.
In a class C IP address, the octets are
“network.network.network.host.” The first three octets together
represent the network address and the final octet is the host address.
In the SBG901 LAN default configuration, 192.168.100 represents the
network address. In the final octet, the host address can range from 2
to 254.
