DEFINITION
The Domain Name System is the Internet system for converting
domain names to IP addresses. A DNS server contains a table
matching domain names such as Internetname.com to IP
addresses such as 192.169.9.1. When you access the world-wide
web, a DNS server translates the URL displayed on the browser
to the destination website IP address. The DNS lookup table is a
distributed Internet database; no one DNS server lists all domain
names to IP address matches.
The CableLabs Data-Over-Cable Service Interface Specification
defines interface standards for cable modems, gateways, and
supporting equipment to deliver data between an HFC network
and computer systems or television sets. To emphasize its use
as a cable modem standard, DOCSIS is now called CableLabs
Certified Cable Modems. Euro-DOCSIS is DOCSIS adapted for
use in Europe.
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.
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 SVG2500 LAN default configuration,
192.168.100 represents the network address. In the final octet,
the host address can range from 2 to 254.
To copy a file from one computer to another. You can use
the Internet to download files from a server to a computer.
A DOCSIS or Euro-DOCSIS cable modem or gateway
