172.31.100.255/20
a. What is the class IP of the numbers?
Class B -> Class Full 16 bits

b. How many network bits are there ?
Network bits -> 20 Bits

c. How many host bits are there ?
Host bits -> (32-20) -> 12 Bits

D. How many host bits borrowed?
Host bits borrowed = Network Bits - Class Full = 20 - 16 = 4 bits

E. How many available subnet ?
Available Subnet -> 2 pangkat n -> n = Borrowed Bits
2 pangkat 4 -> 16

F. How many available host ?
Available host -> 2n - 2 -> n = Host Bits
2 pangkat 12 - 2 = 4094

G. Subnet mask
20 -> 255.255.240.0

H. How many interval for each subnet ?
Interval 16

I. What is the subnet address for the numbers ?
Subnet Address
/20 -> Octet ke 3
interval 16 terdekat dengan 100 - > 96
network ip -> 172.31.96.0 /20

J. What is the broadcast address for the numbers ?
Broadcast Address
172.31.100.255 /20 network selanjutnya
172.31.112.0 /20
berarti broadcastnya
172.31.111.255 /20

K. What are the available hosts ?
available hosts -> 4094
antara : network dengan broadcastnya
172.31.100.255 /20
172.31.112.0 /20
172.31.111.255 /20

L. What are the available hosts for the second subnet ?
172.31.16.0 /20
Broadcast 172.31.31.255 /20

M. Is it public IP Addresses -or- private IP Addresses ?
Private IP Address

N. Define the number! (Is it Unicast Address? Network Address? -or- Broadcast Address?)
Unicast Address
