Hello student here, ip address is given to us and now for 10 subnets we have to use and maximum 12 hosts on each subnet.
00:10
So 10 subnets and each subnet is consist of 12 hosts.
00:14
So we have to calculate the address of 1 ,2 ,3 ,10.
00:18
So to create the 10 subnets first we have to create the 10 subnets.
00:22
So we need to borrow 4 bits from the host portion of the ip address.
00:29
So because 2 raised to power 4 is 16 and it is near to 10.
00:35
So here we are taking, if we take 2 raised to power 3, 8 that is not equal to the 10.
00:42
That's why we are going up to 2 raised to power 4 equal to 16 that is which is the smallest power of 2 that is greater than 10.
00:51
So that's why 2 raised to power 4, 16 is taken.
00:55
Now i have subtracted 4 from 2 raised to power 4 minus 2.
01:01
Why i did this? because this number 2 it consisted of network and broadcast address.
01:10
That's why 2 is subtracted.
01:12
And now the new subnet mask will be 225, 255, 255 and 240.
01:23
So this is the way of the new subnet mask address will be formed.
01:28
And now we have to calculate the address of the host 1, host 2 in this way.
01:34
Then the address for the subnet 0 is 195 .1 .1 .1 and for the address of the subnet 1 will be 195 .1 .1 .17...
