The first IP address of a subnet
What is Network address?
Add one from network address, subtract one from broadcast address
What is calculating first and last usable IP address?
One popular shortcut used for subnetting process?
Magic number method
If your IP address started with a number between 128 and 191, what is your subnet mask?
255.255.0.0
What is a subnet mask?
It is a 32-bit address that divides your IP address into network and host portions.
Why do we go through the process of performing calculations, splitting the network up into smaller pieces, and having to manage all separate IP subnets?
It’s very difficult to connect all devices to all other devices in the world simultaneously.
One way to determine the class of an IP class
What is First octet in the entire address?
What is the subnet mask of this binary form 11111101?
This is not a valid subnet mask.
Why do we use routers to separate the network into smaller pieces and then send our traffic to the next router, who then determines where the next route would ?
Because it is a much simpler way of managing large numbers of devices on a network and still be able to communicate with separate endpoints.
Prior to 1993,how was your subnet mask set?
The subnet mask was set automatically base on what your IP address happened to be.
What is the CIDR prefix of the subnet mask 255.255.252.0 ?
/22
What does VSLM help network administrators determine?
It helps them determine what the best subnet mask might be for a particular network.
The construction of a subnet
What is Network address, First usable host address, Network broadcast address, Last usable host address?
What does CIDR stands for?
Classless Inter-Domain Routing
What does VSLM stand for?
Variable length subnet masks
