Basics of Internet Protocol (IP) Network
Basics of Internet Protocol (IP) Network
IP means Internet Protocol. Every device in an IP-based Network including routers, print
server, and host PCs, needs an IP address to identify its location on the network. To avoid
address conflicts, IP addresses are publicly registered with the Network Information Centre
(NIC). Having a unique IP address is mandatory for those devices participated in the public
network but not in the private TCP/IP local area networks (LANs), such as host PCs under
the management of a router since they do not need to be accessed by the public. Hence,
the NIC has reserved certain addresses that will never be registered publicly. These are
known as
private IP addresses, and are listed in the following ranges:
From 10.0.0.0 to 10.255.255.255
From 172.16.0.0 to 172.31.255.255
From 192.168.0.0 to 192.168.255.255

What are Public IP Address and Private IP Address
As the router plays a role to manage and further protect its LAN, it interconnects groups of
host PCs. Each of them has a private IP address assigned by the built-in DHCP server of the
Vigor router. The router itself will also use the default
private IP address: 192.168.1.1 to
communicate with the local hosts. Meanwhile, Vigor router will communicate with other
network devices through a public IP address. When the data flow passing through, the
Network Address Translation (NAT) function of the router will dedicate to translate
public/private addresses, and the packets will be delivered to the correct host PC in the
local area network. Thus, all the host PCs can share a common Internet connection.

In ADSL deployment, the PPP (Point to Point)-style authentication and authorization is
required for bridging customer premises equipment (CPE). Point to Point Protocol over
Ethernet (PPPoE) connects a network of hosts via an access device to a remote access
concentrator or aggregation concentrator. This implementation provides users with
significant ease of use. Meanwhile it provides access control, billing, and type of service
according to user requirement.
When a router begins to connect to your ISP, a serial of discovery process will occur to ask
for a connection. Then a session will be created. Your user ID and password is authenticated
via
PAP or CHAP with RADIUS authentication system. And your IP address, DNS server, and
other related information will usually be assigned by your ISP.
