Repeat
Given IP189 . 28 . 7 . 31 / 20
#1. & 2.Find the SubNetwork
  1. Binary IP= 10111101 . 00011100 . 00000111 . 00011111 .
  2. With a 20 bit mask
  3. Dotted Decimal Subnet Mask = 255 . 255 . 240 . 0
  4. Binary Subnet Mask = 11111111 . 11111111 . 11110000 . 00000000

    Subnetwork Address = 189 . 28 . 0 . 0

#3.Find the First useable IP address 189 . 28 . 0 . 1
#4.Find the Broadcast address189 . 28 . 15 . 255
#5Find the Last useable IP address189 . 28 . 15 . 254
#6.What is the Total Number of IPs per Subnet?4096
#7.How many useable Hosts address per subnet?4094
#8.What is the Next Subnet Number?189 . 28 . 16 . 0
#9.What IP Class is this?

Class B

#10.How many possible Subnetworks with this class?
Bits this Class = 16
Bits Subnet Mask= 20

2^ 4 = 16
