  12. What are the rules for writing Subnets as
    32bit binary numbers?
    The value must not interleave 1s and 0s

    If 1s exist, they are on the left

    If 0s exist, they are on the right
  13. What are the two parts of a subnet mask?
    Prefix and Host
  14. What are the 3 parts of a classful IP subnet?
    How are the written in Binary?
    • Network Subnet Host
    • 1111... 1111... 0000.....
  15. List some functions of a Subnet Mask
    Defines the size of the Prefix

    Defines the size of the host part of the addresses in the subnet

    Can be used to calculate the number of hosts in the subnet

    Provides a means for the network designer to communicate the design details to the devices in the network

    Under certain circumstances can be used to calculate the number of Subnets in the entire network.

    Can be used in binary calculations of both the subnet ID and the subnet mask
  16. What is the concept of Classless addressing?
    The concept that an IPv4 address has two parts- the prefix part plus the host part as defined by the mask with no consideration of the class.
  17. What is the concept of Classfull addressing?
    The concept that an IPv4 address has three parts- network, subnet, and host as defined by the mask and the class.
  18. What is the decimal equivalant of this octet:

    .1000000.
    128

    add 1 to the /mask
  19. What is the decimal equivalant of this octet:

    11000000
    192

    add 2 to the /mask
  20. What is the decimal equivalant of this octet:

    11100000
    224

    add 3 to the/mask
  21. What is the decimal equivalant of this octet:

    .11110000.

    add 5 to the /mask
  23. What is the decimal equivalant of this octet:

    .11111100.
    252

    add 6 to the /mask
  24. What is the decimal equivalant of this octet:

    .11111110.
    254

    add 7 to th /mask
  25. What is the decimal equivalant of this octet:

    .11111111.
    255
