how to calculate subnet mask?
e.g - 200.10.10.0 --> usable host 16
what is 6th usable subnet range?
: from here we know every subnet must have 16 hosts..
so 6th usable subnet range is from 6th to 7th subnet
6th subnet address = 16 x 6 = 96
7th subnet address = 16 x 7 = 112
the answer is : 200.10.10.96 to 200.10.10.111
what is subnet number for 4th usable subnet?
: 16 x 4 = 64
the answer is : 200.10.10.64
what is subnet broadcast address for the 3rd usable subnet?
: take 4th subnet becoz the broadcast address of 3rd subnet is before 4th subnet address.
16 x 4 =64
the answer is : 200.10.10.63
what are the assignable address for the 5th usable subnet?
: 16 x 5 = 80 ; 16 x 6 = 96
range 200.10.10.80 to 200.10.10.95 ... then exclude address and broadcast
the answer is : 200.10.10.81 to 200.10.10.94
