IP address Part2 includes class,range and reserved bits

 IP Address part-2

So Why should we know IP address???? Its a big and good question!!!!!!!!!!!!

Lets try to understand........

The part “address” relates to address of ???????

These addresses are used by the host e.g.... PC, Network Printer, and other network devices..

An IP address is the address of the network devices so that they can communicate with each other. What else required for communication???

Apart from IP address there is one more important part that is known as Subnet Mask.

As the name includes mask that means masking of an IP address. These are co-related with each other. First I will let you know more about IP address.

IP address is divided into different five classes..

ClassA

ClassB

ClassC

ClassD

ClassE

Each class of IP addresses are having some specification.

Range

ClassA-0-127 (0 and 127 are reserved)

ClassB-128-191

ClassC-192-223

ClassD-224-239

ClassE-240-255(255 is reserved)

These ranges are used to identify the IP address classes.

Eg.

10.10.10.200--- ClassA

180.1.1.240-----ClassB

200.1.1.12-------ClassC

232.34.52.23----ClassD

254.23.23.34----ClassE

To identify the class we check for 1^st octet of an IP address.

Now the question arise that how many bits are reserved to identify the class.

Lets understand...

Range of the ClassA- 0 to 127

we write it in binary 00000000 to 01111111

0xxxxxxx to 0xxxxxxx

here I can see that in this range only 0 is common and other values can be “1” or “0” so the reserved bit is only “one” that is 0

Range of classB- 128 to 191

we write it in binary 10000000 to 10111111

10xxxxxx to 10xxxxxx

here I can see that in this range “10” are common and other values can be “1” or “0”so the reserved bit is “two” that is “10”
