IP Subnetting and NAT ch8 Flashcards
1
Q
The number of subnets is
A
2^n where n is the number of subnet bits
2
Q
The number of hosts per subnet is
A
2^n-2 where n is the number of 0’s(unmasked bits)
3
Q
example how many subnets and host per subnets in /26
A
2^2 = 4subnets
2^6 -2 = 62 hosts per subnet
4
Q
example what is the subnet mask of /28 the #of subnets, the #of hosts per subnet
A
240mask
2^4(4bits) = 16subnets
2^4(4 0’s)-2 14host per subnet
