IP Addressing


The way

by which we provide IP Address to our system or device
.


IP Address


It is 32 bit logical address which provides unique identification to pc
and device. It is divided into four parts. Each part is known as Octate and
Each Octate is 8 bit.


Classes
of

IP


Class
A (
0
-
127)


Class B (128
-
192)


Class
C (

lass
D (

-

Class
E (
240
-
255)



0 is used for Default Routing


127 is used for Loopback Testing


Class

D is used for Multicasting


Class E is used for Research & Development




Subnet Mask


It Provides
Information about

NID and HID bits and it also provide
information about Host Range. Default Subnet Mask of each class.


Class A


255.0.0.0


Class B


255.255.0.0


Class C


255.255.255.0



Subnetting


The way by which we divide large network into small network
known

as
S
ub network

and the process which is used to make subnet work known
as
Subnetting
.

VLSM (Variable Length Subnet Mask)


It is process which divides a large network into small network according to
host range. If host range will be vary from subnet mask will
also change.







Supernetting (
S
ummarization)


It is a process in which multiple network address will be added and
represented by a single ID.


Mainly this process is used by ISP to reduce the load from their large
network. Routing protocols use this pr
ocess to reduce the routing table size.












Router


It is centralized network device which provides communication between
different


different networks. It is a
L
ayer 3 device means it works on Network
Layer. It
receives

and forwards the packet.
It provides more security, scalability
and flexibility to the networks.

Types of Routers

1.

Modular Router
:
-

Those Routers in which slots are present and we can
increase the router ports (interface).
















2.

Demodular Router
:
-

We can’t increase the
port (
interface) because
it does
not provide slot facility.






Router Series
:
-


Modular
-

1800,2600,2800,3500,3800,4500,7200,7400,10000,12000,etc.


Demodular


700, 800, 1000, 1600, 2500, etc.
