Answer / s.m.feroz ahmed

Hi,

This is the Concept of Ip Addressing and this requires more
and more specific while assigning IP address Ip Addressing
is divided into 4 Class A,B,C,D where range of ip address
on which subnetting is done.So class A ip address Subnet
mask is 255.0.0.0 for class B it is 255.255.0.0 for Class C
255.255.255.0 and for class D it is hexa decimal which is
as 2^ .So for class C Ip addressing Subnet mask will always
be 255.255.255.0 range from 0 to 255 again like
255.255.255.0
255.255.255.1
255.255.255.2
255.255.255.3
255.255.255.4

|till 255.255.255.255.In this manner Ip addressing is
classified and the process of IP Addressing and Subnetting
is the main topic in Networking concept without the concept
of IP addressing noone can proceed further in Networking
field.
One will not accept entries into Ip addressing if Class C
Ip address and Subnet Mask of class A is assigned and will
through an error message.

Answer / jitendra

Good thought
But soory we can not do this one becoz the ip address is
not like some numric value and numric mask

in ip address each value determine the bit value (please
refefer the ip header topic in the ccna book)

or do one thing please write any ip address in the form of
binary format that is 0 and 1 format from there u will come
to know that why we canot replase the calss a mask with
class c mask

if we will do it then we have to change whole modern
physiss and we have to also devlaop the new binary consepts
and then i have to do engineering again quit impossible.

so we have to look towrds the ipv6
but this is a good thought
