2.1 CABLE OVERVIEW
This section describes some of the concepts related to the Cable screens.
2.1.1 DOCSIS
The Data Over Cable Service Interface Specification (DOCSIS) is a
telecommunications standard that defines the provision of data services) Internet
access) over a traditional cable TV (CATV) network.
Your CVE-30360 supports DOCSIS version 3.0.
2.1.2 IP ADDRESSES AND SUBNETS
Every computer on the Internet must have a unique Internet Protocol (IP) address.
The IP address works much like a street address, in that it identifies a specific
location to which information is transmitted. No two computers on a network can have
the same IP address.
2.1.2.1 IP ADDRESS FORMAT
IP addresses consist of four octets (8-bit numerical values) and are usually
represented in decimal notation, for example 192.168.1.1. In decimal notation, this
means that each octet has a minimum value of 0 and a maximum value of 255.
An IP address carries two basic pieces of information: the “network number” (the
address of the network as a whole, analogous to a street name) and the “host ID”
(analogous to a house number) which identifies the specific computer (or other
network device).
2.1.2.2 IP ADDRESS ASSIGNMENT
IP addresses can come from three places:
The Internet Assigned Numbers Agency (IANA)
