If a device has an IP address of 172.16.5.10 with a subnet mask of 255.255.255.0

If a device has an IP address of 172.16.5.10 with a subnet mask of 255.255.255.0, what is its network address?

If a device has an IP address of 172.16.5.10 with a subnet mask of 255.255.255.0, what is its network address?

Step 1: Understand the IP address and subnet mask. The IP address is 172.16.5.10 and the subnet mask is 255.255.255.0.
Step 2: Convert the subnet mask to binary. 255.255.255.0 in binary is 11111111.11111111.11111111.00000000.
Step 3: Identify the network part and the host part. The '1's in the subnet mask indicate the network part, and the '0's indicate the host part.
Step 4: Convert the IP address to binary. 172.16.5.10 in binary is 10101100.00010000.00000101.00001010.
Step 5: Apply the subnet mask to the IP address. Keep the bits where the subnet mask has '1's and set the bits where the subnet mask has '0's to '0'.
Step 6: The result of applying the subnet mask to the IP address gives you the network address in binary: 10101100.00010000.00000101.00000000.
Step 7: Convert the binary network address back to decimal. This gives you 172.16.5.0.
Step 8: Therefore, the network address is 172.16.5.0.
