What is an IP address?
A number that uniquely identifies a device on the internet.
What are the different parts of an IP address?
A part of the IP address represents the network and another part represents the device.
What are the different kinds of networks and how are they indicated in an IPv4 address?
Class A network, the biggest, is represented by everything before the first period (203) in the IPv4 address 203.0.113.112. The rest is the device.
Class B network, a smaller network, is represented by everything before the second period (203.0) in the IPV4 address 203.0.113.112. The rest is the device.
Class C network, the smallest network, is represented by everything before the third period (203.0.113) in the IPv4 address 203.0.113.112. The rest is the device,
Why is subnetting necessary?
Subnetting narrows down the IP address to usage within a range of devices, which makes finding a device on a large network practical.
What is a subnet mask?
A subnet mask is like an IP address, but for only internal usage within a network.
What is an example of a subnet mask and what are its parts?
255.255.255.0 - this means that the first three octets of an IP address are the network portion, and the last octet is for the hosts.
How are subnets indicated using a subnet mask?
Given 255.255.255.0, the binary representation of the last integer following the third period determines how and whether you can divide the binary representation of the device portion of an IP address into one or more subnets.
