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 CODA-4x8x:
The public network (Wide Area Network or WAN) is the link between the cable
connector and your Internet Service Provider. Your CODA-4x8x’s IP address on
this network is assigned by your service provider.
