How is the broadcast address calculated using the magic number?
Press to flip
Add the magic number to the subnet ID and subtract one.
What are the first and last host addresses in the subnet for IP 165.245.77.14 with subnet mask 255.255.240.0?
The first host address is 165.245.64.1 and the last host address is 165.245.79.254.
What is the first and last host address for the subnet of IP 10.180.122.244 with subnet mask 255.248.0.0?
The first host address is 10.176.0.1 and the last host address is 10.183.255.254.
In subnetting, what are the key addresses that need to be identified?
Network address (Subnet ID), Broadcast address, First available host address, Last available host address
What is the main objective of subnetting an IP address?
To support more than one network address and a specific number of devices per subnet.
Give an example calculation of the magic number for the subnet mask 255.255.240.0.
For the subnet mask 255.255.240.0, the interesting octet is 240. The magic number is 256 - 240 = 16.
What is the broadcast address for the IP address 165.245.77.14 with subnet mask 255.255.240.0?
The broadcast address is 165.245.79.255.
What does CIDR stand for in subnetting?
Classless Inter-Domain Routing
What is the purpose of the magic number in subnetting?
To simplify the subnetting process by allowing quick calculations with minimal mathematical operations.
Why might one use charts in the magic number method?
Charts can simplify finding magic numbers and host ranges for various subnet sizes, making calculations quicker.
Find the broadcast address for IP 10.180.122.244 with subnet mask 255.248.0.0.
The broadcast address is 10.183.255.255.
How do you find the interesting octet in a subnet mask?
It is the octet in the subnet mask that is neither 255 nor 0.
What is the subnet ID of the IP address 165.245.77.14 if the subnet mask is 255.255.240.0?
The subnet ID is 165.245.64.0.
How do you calculate the magic number from the interesting octet?
The magic number is calculated as 256 minus the value of the interesting octet.
Determine the subnet ID for IP 10.180.122.244 with subnet mask 255.248.0.0.
The subnet ID is 10.176.0.0.
