Final answer:

The network ID for the IP address 10001100.10000101.00011100.01001000 with the subnet mask 11111111.11111000.00000000.00000000 is 140.132.0.0.

Step-by-step explanation:

When determining the network ID of an IP address with a given subnet mask, you perform a bitwise AND operation between the two. In this case, the IP address is 10001100.10000101.00011100.01001000 and the subnet mask is 11111111.11111000.00000000.00000000. After performing the AND operation on these binary numbers, the network ID is the combination of the bits of the IP address where the subnet mask has a corresponding bit of 1. The bits where the subnet mask has 0s will be turned to 0 in the network ID.

This process gives us the network ID: 10001100.10000100.00000000.00000000, which can be converted to the dotted-decimal format as 140.132.0.0.

The given IP address is 10001100.10000101.00011100.01001000 and the subnet mask is 11111111.11111000.00000000.00000000. To find the network ID, we need to perform a logical AND operation between the IP address and the subnet mask.

Performing the AND operation on each corresponding bit of the IP address and the subnet mask gives us the network ID:

IP address: 10001100.10000101.00011100.01001000

Subnet mask: 11111111.11111000.00000000.00000000

Network ID: 10001100.10000101.00000000.00000000

Therefore, the network ID is 140.133.0.0.
