30. Identifying Local and Remote Addresses
1. Convert the IP address to binary.
You can use a calculator to do this.
2. Convert the subnet mask to binary.
3. Draw a vertical line after the last one in the subnet mask:
Everything to the left of the line is the network ID.
Everything to the right of the line is the host ID.
4. Determine the network ID in binary.
This is as simple as copying the IP address in binary to the left of the line and writing 0s to the right of the line.
5. Convert the network ID to decimal. 30
