Final answer:
The subnet for a /22 CIDR block on IP address 192.158.80.0 can be calculated by using CIDR notation and subnetting rules. The network portion of the IP address is determined using the number after the slash in the CIDR notation, and the host portion is determined by the remaining bits.
Step-by-step explanation:
The subnet for a /22 CIDR block on IP address 192.158.80.0 can be calculated by understanding the CIDR notation and subnetting rules. In CIDR notation, the number after the slash represents the number of bits used for the network portion of the IP address. For a /22 CIDR block, 22 bits are used for the network portion, leaving 10 bits for the host portion. Since each bit can have 2 possible values (0 or 1), there are 2^10 = 1024 possible host addresses within this subnet.
To determine the subnet, we start with the given IP address (192.158.80.0) and convert it to binary form: 11000000.10011110.01010000.00000000. Since there are 22 network bits, the subnet is 11000000.10011110.01010000.00 (with 10 zeroes at the end).
So, the subnet for a /22 CIDR block on IP address 192.158.80.0 is 192.158.80.0/22, which means the network portion spans from 192.158.80.0 to 192.158.83.255, while the host portion can have addresses ranging from 192.158.80.1 to 192.158.83.254.
