192.168.4.2
192.256.212.5
Finding:
1. How to identify an IP address
2. How to identify class of an IP address
3. Specify Network and Host portion
4. Find subnet mask
5. Find Broadcast Address
6. Find Network Address
7. Find Network bits and Host bits
8. And also find Total Host and Usable Host
>> 10.12.5.2
1. How to identify an IP address
10.12.5.2 is valid IP address, because we know that an IP address every portion bits
number is 8 and every bit portion decimal range 0-255
2. How to identify class of an IP address
This IP address’s class A [Class A: 0-127]. We find first 8 bit portion that decimal
range Between 0 to 127, this first number is 10.

How to identify an IP address
172.125.2.5 is valid IP address, because we know that an IP address every portion bits number is 8 and
every bit portion decimal range 0-255
How to identify class of an IP address
This IP address’s class B[Class B: 128-191]. We find first 8 bit portion that decimal range between 128 to
191, this first number is 172.

How to identify an IP address
192.168.4.2 is valid IP address, because we know that an IP address every portion bits number is 8 and
every bit portion decimal range 0-255
How to identify class of an IP address
This IP address’s class C[Class C: 192-223]. We find first 8 bit portion that decimal range between 192 to
223, this first number is 192.
