subnet mask,default subnet mask,what is subnetwork address if destination address is 200.45.34.36

Question

What is this subnet mask and default subnet mask?

What is the Subnetwork address if the destination address is 200.45.34.36 and the subnet mask is 255.255.240.0 ?

Answer 1

 A Subnet mask is a 32-bit number that masks an IP address, and divides the IP address into network address and host address.It is called a subnet mask because it is used to identify network address of an IP address by perfoming a bitwise AND operation on the netmask.

The default subnet masks for class A networks is 255.0.0.0, for class B is 255.255.0.0, and for class C is 255.255.255.0, which signify a network without subnets

Take AND operation between destination address and subnet mask.

Subnet address is 200.45.32.0

how you did dear sir ? which operation you did please tell ??

I have mentioned it in the answer.

Do bitwise AND operation between IP address and subnet mask .

250.240.0.0

this is class E network 

In this Class there are no host bits and network bits so for class D and E Network mask and sub net mask are not defined.

Answer 2

What is this subnet mask and default subnet mask?

ans : default subnet is the subnet mask of classes 

class A: 255.0.0.0

class B : 255.255.0.0

 class C: 255.255.255.0

subnet mask of any given address is the division of small network inside the network you may say partition of host addresses inside the network .

What is the Subnetwork address if the destination address is 200.45.34.36 and the subnet mask is 255.255.240.0 ?

       200.45.00100010.36          

AND 255.255.11110000.0

result: 200.45.00100000.0= 200.45.32.0 is the subnet mask at position 32

Answer 3

This is class  C IP so  default n/w Mask=255.255.255.0

given mask=255.255.240.0

so networks bits are converted into 0's =>this is superneting not sub netting.
