IP ADDRESSING EASY ALL MAIN CONCEPTS

IP's Are 2 Type
1.Physical IPs
   Mac Address
2.Logical IPs
IPV4 And IPV6

In IPV4
Public IP
Private IP

example of IP

192.168.1.1

Ip = Network ID + Host ID;

Ipv4=32Bit Address.

Max Value = 0 to 255.

Classes Of  IP

5 Type OF Class
Class A  1.0.0.0 to 126.0.0.0
Class B  128.255.0.0 to 191.255.0.0
Class C  192.255.255.0 to 223.255.255.0
Class D  224 to 239  For Testing Purpose Used
Class E  240 to 255 For Research Purpose


Note: 127.0.0.0 Ip is allcoated For LoopBack Address.
Theoretically Range 0 to 127 Class A.

For Check You Can Ping 127.0.0.0 to Your CMD(Command Prompt).

Now How TO Find IPs Network and Host ID.

First Check Class First octal Belongs To Which Class.

Next Refer This

Class A   N.H.H.H
Class B   N.N.H.H
Class C   N.N.N.H

Where N= Network ID;
and H = Host ID.

And Network=1bit.
Host =0bit.

How To Find Subnet Mask IP.
Binary to Decimal Value 11111111 => 255
Example:
Class A= 115.10.10.20
Network+Host = 11111111.00000000.00000000.00000000
So Subnet Mask  =255.0.0.0

Class B =255.255.0.0
Class C=255.255.255.0

How to Convert IPs to Binary ?
Example
192.168.37.200

2^7  2^6 2^5 2^4 2^3 2^2 2^1  2^0
128  64  32   16  8    4    2    1

concate the Value and Make the 192
Convert In 8 bit binary
Note:Take 1 for Which Add Values and 0 For Not Take Value In Addition.

128+64=192          so  1  1   0  0   0   0   0  0   this is binary of  192
128+32+8 =168     so  1  0  1   0   1   0   0    0  this is binary of 168
32+4+1 =37           so  0  0   1    0  0   1    0   1  this is binary of 37
128+64+8=200      so   1  1  0  0  1   0   0   0   this is binary of 200

Private Ip Detail

Class A= 10.0.0.0
Class B =172.16.x.x-172.31.x.x
Class C = 192.x.x.x

Reserved For  Private IP.


How Many Computer You Connect With The Given Ip

176.10.0.0

Network ID and Broadcast Id.

Example

150.10.20..30

Find Network ID?
Find  Broadcst ID?
Find Number OF Host?


150.10.0.0 => Network Id
150.10.255.255 => BroadCast Id

Kitne Bit Host Ke Liye Available Hai

2^16 -2=65,534 Computers You Can Connect with This Ip.

Note: Har network Ke under 2 Ip hosti hai jo App Kisi Or ko Allocate ni Kar Sakte;
That's Why  -2 Used.
And 2^16 is Used Because 16bit Host Available.


one more Example

11.200.200.200

Network Id = 11.0.0.0
Broadcast Id =11.255.255.255
no of Host= 2^ 24 -2 = 1,67,77,214
