Given IP120 . 146 . 181 . 217 / 10
#1. & 2.Find the SubNetwork
  1. Binary IP= 01111000 . 10010010 . 10110101 . 11011001 .
  2. With a 10 bit mask
  3. Dotted Decimal Subnet Mask = 255 . 192 . 0 . 0
  4. Binary Subnet Mask = 11111111 . 11000000 . 00000000 . 00000000

    Subnetwork Address = 120 . 128 . 0 . 0
