Assignment #5 debriefing

Quiz #1: Subnetting

  • (10 questions, 1/2 hour only)
  • Make sure to bring in your stand-alone calculator, pencils, and an eraser.
  • Make sure that you’re proficient and comfortable with the decimal to Base-256 dotted-decimal conversion method. Practice makes improvement!
    • “Subnet number” x starts from 0, so do not subtract one before you multiply by the number of addresses per subnet. The result will be the number of addresses to add to the first address in the block to get to the first address in subnet #.
      • For example: What’s the subnet range for subnet “number” 1023?
      • i.e. The 1024th subnet is subnet number 1023.
    • The “Nth/st/rd subnet” starts from 1, so you’ll have to subtract one before you multiply by the number of addresses per subnet. The result will be the number of addresses to add to the first address in the block to get to the first address in the Nth/st/rd subnet.
      • For example: What’s the subnet range for the 5028th subnet?
