IP ADDRESS:
Ip address its mostly like the identification number of the computer.
Its a address Of the Computer. There is two types of address : IPv4 and IPv6 in this we see IPv4
STRUCTURE OF IP ADDRESS:
The total length of IPv4 is 32 bits
They are separated in 4 blocks and each blocks contains 8 bits
SUBNETTING:
Subnetting means breaks the network into sub-networks which means that I break the 1 network into 4 subnetworks
In this we separate the IPv4 into 2 parts: Network part and host part
Network Part is gonna remain same for subnet only host part is gonna change for each machine in the subnet
Network part is gonna represent the whole subnet and the host part represent how many machines are allowed or maximum limit of the machines are connect to that subnet
That Network part and Host part can be defined by CIDR - Classless Inter Domain Routing that tells how many host or machines can connect to that specific subnet
CIDR - Classless Inter Domain Routing:
If I have a IP address like 12.0.9.15/24 in this 24 is CIDR that represents the network part of the subnet
24 bits are allocated for the network part so we can use remaining 8 bits for machines that I can connect 255 machines in that specific subnet.
Not Likely I can connect the whole 255 machines that 12.0.9.0/24 is for root and last IP address of that subnet also not given to the machine.
