Hello students, to create the subnet for the 4 departments with the given requirement, we need to determine the appropriate subnet mask for each subnet based on the number of the hosts needed.
00:12
The number of hosts needed for each department are given to us.
00:15
Number 1, department a needs 200 hosts, department b needs 61, department c needs 55 hosts and department d needs 41 hosts.
00:26
So here are the total hosts provided to us.
00:30
Now let's calculate the subnet mask and the address range for each department.
00:37
Now subnetting department a having the 200 hosts, subnet mask 255 .255 .255 .128.
00:45
So this is the subnet host and now subnet range will be from 0 to 127 because 128 so accommodate 128 0 to 127.
00:55
So the first address will be 199 .2 .1 .0 it is given to us and the last address will be 199 .2 .1 and after that 127 will be this because of this one and after for the department b it accommodates 61 hosts.
01:17
Now the subnet mask will be 255 .255 .255 .192.
01:24
So after that subnet range will be from 128 because here 120 is up to 127.
01:32
So we will use further it's 128 to by adding now it's a 61.
01:38
So here after it will go up to the 191.
01:45
Now the first address will be it will be from 128 and the last address will be up to 191.
01:52
Now the department c, department c subnet mask will be 255 .255 .255 .224 and here the subnet range will be from 192 to 223 from this 192 to 223 this will be the range and the first address will be 199 .2 .1 .192 and the last address is 223...
