Question

You are a network admin who has been given thenetwork 10.10.4.0/23. You want to divide it into four subnets.

1)What subnet mask would all the computers now have ?2)Draw the "network pie" for this network. Show subnet number as well as the Network ID and Broadcast ID for each of the subnets.

Answer 1

To divide the network 10.10.4.0/23 into four subnets, we change the subnet mask to /25 (255.255.255.128). This results in four subnets with corresponding Network IDs and Broadcast IDs for each.

Step-by-step explanation:

To divide the network 10.10.4.0/23 into four subnets, we need to consider the current subnet mask and then borrow bits to create the additional subnets. The given network 10.10.4.0 has a subnet mask of /23, which is 255.255.254.0. Since we're dividing into 4 equal subnets, we need to borrow 2 bits from the host part of the address (as 2^2 = 4). This changes the subnet mask from /23 to /25, which gives us the following subnet mask: 255.255.255.128.

The "network pie" showing each subnet, Network ID, and Broadcast ID would look like this:

• Subnet 1: Network ID: 10.10.4.0, Broadcast ID: 10.10.4.127
• Subnet 2: Network ID: 10.10.4.128, Broadcast ID: 10.10.4.255
• Subnet 3: Network ID: 10.10.5.0, Broadcast ID: 10.10.5.127
• Subnet 4: Network ID: 10.10.5.128, Broadcast ID: 10.10.5.255
