Questions & Step-by-Step Solutions
If a host has an IP address of 192.168.1.10 and 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 192.168.1.10 and the subnet mask is 255.255.255.0.
Step 2: Convert the IP address and subnet mask to binary format. The IP address 192.168.1.10 in binary is 11000000.10101000.00000001.00001010. The subnet mask 255.255.255.0 in binary is 11111111.11111111.11111111.00000000.
Step 3: Perform a bitwise AND operation between the binary IP address and the binary subnet mask. This means you compare each bit of the IP address with the corresponding bit of the subnet mask.
Step 4: The result of the bitwise AND operation is: 11000000.10101000.00000001.00000000.
Step 5: Convert the result back to decimal format. The binary 11000000.10101000.00000001.00000000 converts to 192.168.1.0.
Step 6: The network address is therefore 192.168.1.0.
