IP Subnetting and NAT ch8

Question 1

The number of subnets is

Answer 1

2^n where n is the number of subnet bits

Question 2

The number of hosts per subnet is

Answer 2

2^n-2 where n is the number of 0’s(unmasked bits)

Question 3

example how many subnets and host per subnets in /26

Answer 3

2^2 = 4subnets

2^6 -2 = 62 hosts per subnet

Question 4

example what is the subnet mask of /28 the #of subnets, the #of hosts per subnet

Answer 4

240mask
2^4(4bits) = 16subnets
2^4(4 0’s)-2 14host per subnet
