Final answer:
The subnet number for the given IP address and subnet mask is 180.22.230.128 while the broadcast address is 180.22.230.255 and the valid IP range is from 180.22.230.129 to 180.22.230.254.
Step-by-step explanation:
The given IP address is 180.22.230.217 with a subnet mask of /25. To find the subnet number, we need to calculate the subnet mask. In this case, the subnet mask is 255.255.255.128. To calculate the subnet number, we perform a bitwise AND operation between the given IP address and the subnet mask:
180.22.230.217 & 255.255.255.128 = 180.22.230.128
So, the subnet number for the given IP address and subnet mask is 180.22.230.128. The broadcast address can be calculated by performing a bitwise OR operation between the subnet number and the inverted subnet mask:
180.22.230.128 | 0.0.0.127 = 180.22.230.255
Therefore, the broadcast address for the given IP address and subnet mask is 180.22.230.255. Finally, the valid IP range can be obtained by incrementing the subnet number by 1 and excluding the network ID and the broadcast address:
The valid IP range is from 180.22.230.129 to 180.22.230.254.
