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
What are the two parts of a subnet mask?
Prefix and Host
What are the 3 parts of a classful IP subnet?
How are the written in Binary?
Network Subnet Host
1111... 1111... 0000.....
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
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.
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.
