Status Overview

3.1.1
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 CGN3 supports DOCSIS version 3.0.

3.1.2
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.
3.1.2.1
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).
3.1.2.2
IP Address Assignment
IP addresses can come from three places:
The Internet Assigned Numbers Agency (IANA)
Your Internet Service Provider
You (or your network devices)
IANA is responsible for IP address allocation on a global scale, and your ISP assigns
IP addresses to its customers. You should never attempt to define your own IP
addresses on a public network, but you are free to do so on a private network.
In the case of the CGN3:
The public network (Wide Area Network or WAN) is the link between the cable
connector and your Internet Service Provider. Your CGN3’s IP address on this
network is assigned by your service provider.

The private network (in routing mode - see
Routing Mode
on page
38
) is your
Local Area Network (LAN) and Wireless Local Area Network (WLAN), if
enabled. You are free to assign IP addresses to computers on the LAN and
WLAN manually, or to allow the CGN3 to assign them automatically via DHCP
(Dynamic Host Configuration Protocol). IANA has reserved the following blocks
of IP addresses to be used for private networks only:
If you assign addresses manually, they must be within the CGN3’s LAN subnet.
3.1.2.3
Subnets
A subnet (short for sub-network) is, as the name suggests, a separate section of a
network, distinct from the main network of which it is a part. A subnet may contain all
of the computers at one corporate local office, for example, while the main network
includes several offices.
In order to define the extent of a subnet, and to differentiate it from the main network,
a subnet mask is used. This “masks” the part of the IP address that refers to the main
network, leaving the part of the IP address that refers to the sub-network.
Each subnet mask has 32 bits (binary digits), as does each IP address:
A binary value of
1
in the subnet mask indicates that the corresponding bit in the
IP address is part of the main network.
A binary value of
0
in the subnet mask indicates that the corresponding bit in the
IP address is part of the sub-network.
For example, the following table shows the IP address of a computer (
192.168.1.1
)
expressed in decimal and binary (each cell in the table indicates one octet):
