To calculate the network address of an IP address like 104.1.94.218, you need two key components:

1. IP Address: 104.1.94.218
2. Subnet Mask: The subnet mask determines how many bits of the IP address are allocated to the network portion and the host portion.

Steps to Calculate the Network Address

Step 1: Find the Subnet Mask

If no subnet mask is specified, the default is used based on the IP address class:

• Class A: 255.0.0.0
• Class B: 255.255.0.0
• Class C: 255.255.255.0

For this example, let’s assume a Class C subnet mask of 255.255.255.0.

Step 2: Convert to Binary

1. Convert the IP address and subnet mask to binary:

Step 3: Perform a Bitwise AND

• Combine the IP address and subnet mask using a bitwise AND operation. This means keeping a 1 if both bits are 1, otherwise setting it to 0.

| IP Address | 01101000.00000001.01011110.11011010 |
| Subnet Mask | 11111111.11111111.11111111.00000000 |
| Network Address | 01101000.00000001.01011110.00000000 |

Step 4: Convert Back to Decimal

• Convert the binary network address back to decimal:

Final Result

• IP Address: 104.1.94.218
• Subnet Mask: 255.255.255.0
• Network Address: 104.1.94.0

Notes

1. If a different subnet mask is provided (e.g., 255.255.254.0), the calculations would change accordingly.
2. Knowing the network address is essential for subnetting, routing, and network management tasks.
