Answer:
For each IP address, we will calculate the network, first address, last address, and broadcast address.
IP address 209.118.171.252/24:
The subnet mask is /24, which means that the first 24 bits of the IP address are part of the network address, and the remaining 8 bits are for hosts.
The network address can be calculated by ANDing the IP address with the subnet mask:
IP address: 209.118.171.252
Subnet mask: 255.255.255.0 (or /24 in CIDR notation)
Network address: 209.118.171.0
The first address in the subnet is the network address plus 1, and the last address is the broadcast address minus 1. The broadcast address can be calculated by ORing the network address with the bitwise NOT of the subnet mask.
First address: 209.118.171.1
Last address: 209.118.171.254
Broadcast address: 209.118.171.255
IP address 48.107.19.142/10:
The subnet mask is /10, which means that the first 10 bits of the IP address are part of the network address, and the remaining 22 bits are for hosts.
The network address can be calculated by ANDing the IP address with the subnet mask:
IP address: 48.107.19.142
Subnet mask: 255.192.0.0 (or /10 in CIDR notation)
Network address: 48.64.0.0
The first address in the subnet is the network address plus 1, and the last address is the broadcast address minus 1. The broadcast address can be calculated by ORing the network address with the bitwise NOT of the subnet mask.
First address: 48.64.0.1
Last address: 48.127.255.254
Broadcast address: 48.127.255.255
IP address 179.9.134.48/7:
The subnet mask is /7, which means that the first 7 bits of the IP address are part of the network address, and the remaining 25 bits are for hosts.
The network address can be calculated by ANDing the IP address with the subnet mask:
IP address: 179.9.134.48
Subnet mask: 254.0.0.0 (or /7 in CIDR notation)
Network address: 178.0.0.0
The first address in the subnet is the network address plus 1, and the last address is the broadcast address minus 1. The broadcast address can be calculated by ORing the network address with the bitwise NOT of the subnet mask.
First address: 178.0.0.1
Last address: 181.255.255.254
Broadcast address: 181.255.255.255
