Repeat
Given IP207 . 230 . 168 . 74 / 25
#1. & 2.Find the SubNetwork
  1. Binary IP= 11001111 . 11100110 . 10101000 . 01001010 .
  2. With a 25 bit mask
  3. Dotted Decimal Subnet Mask = 255 . 255 . 255 . 128
  4. Binary Subnet Mask = 11111111 . 11111111 . 11111111 . 10000000

    Subnetwork Address = 207 . 230 . 168 . 0

#3.Find the First useable IP address 207 . 230 . 168 . 1
#4.Find the Broadcast address207 . 230 . 168 . 127
#5Find the Last useable IP address207 . 230 . 168 . 126
#6.What is the Total Number of IPs per Subnet?128
#7.How many useable Hosts address per subnet?126
#8.What is the Next Subnet Number?207 . 230 . 168 . 128
#9.What IP Class is this?

Class C

#10.How many possible Subnetworks with this class?
Bits this Class = 24
Bits Subnet Mask= 25

2^ 1 = 2
