Answer the following using VLSM<\/p>\n\n\n\n

\"\"\/<\/figure>\n\n\n\n

The Correct Answer and Explanation is :<\/strong><\/mark><\/p>\n\n\n\n

I’ll calculate the subnet masks, subnets, and IP address ranges using Variable Length Subnet Masking (VLSM)<\/strong> for both 10.0.0.0\/16<\/strong> and 120.0.0.0\/12<\/strong> networks.<\/p>\n\n\n\n

1. Subnetting 10.0.0.0\/16 Network<\/strong><\/h3>\n\n\n\n

Given the 10.0.0.0\/16<\/strong> network, let’s subnet it to accommodate the required hosts.<\/p>\n\n\n\n

Broadcast Addresses<\/strong>:<\/p>\n\n\n\n

    \n
  • A:<\/strong> 10.0.0.31<\/li>\n\n\n\n
  • B:<\/strong> 10.0.0.47<\/li>\n\n\n\n
  • C:<\/strong> 10.0.0.55<\/li>\n\n\n\n
  • D:<\/strong> 10.0.0.59<\/li>\n<\/ul>\n\n\n\n

    Unused IPs: The remaining part of the 10.0.0.0\/16<\/strong> can be further subnetted.<\/p>\n\n\n\n

    \n\n\n\n

    2. Subnetting 120.0.0.0\/12 Network<\/strong><\/h3>\n\n\n\n

    Given the 120.0.0.0\/12<\/strong> network, let’s subnet it.<\/p>\n\n\n\n

    Network<\/strong><\/th>Hosts Needed<\/strong><\/th>Next Power of 2<\/strong><\/th>Subnet Mask (CIDR)<\/strong><\/th>Dotted Decimal<\/strong><\/th>Network Address<\/strong><\/th>IP Address Range<\/strong><\/th><\/tr><\/thead>
    A<\/strong><\/td>30<\/td>32<\/td>\/27<\/strong> (255.255.255.224)<\/td>120.0.0.0<\/td>120.0.0.1 – 120.0.0.30<\/strong><\/td><\/td><\/tr>
    B<\/strong><\/td>12<\/td>16<\/td>\/28<\/strong> (255.255.255.240)<\/td>120.0.0.32<\/td>120.0.0.33 – 120.0.0.46<\/strong><\/td><\/td><\/tr>
    C<\/strong><\/td>4<\/td>8<\/td>\/29<\/strong> (255.255.255.248)<\/td>120.0.0.48<\/td>120.0.0.49 – 120.0.0.54<\/strong><\/td><\/td><\/tr>
    D<\/strong><\/td>2<\/td>4<\/td>\/30<\/strong> (255.255.255.252)<\/td>120.0.0.56<\/td>120.0.0.57 – 120.0.0.58<\/strong><\/td><\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

    Broadcast Addresses<\/strong>:<\/p>\n\n\n\n

      \n
    • A:<\/strong> 120.0.0.31<\/li>\n\n\n\n
    • B:<\/strong> 120.0.0.47<\/li>\n\n\n\n
    • C:<\/strong> 120.0.0.55<\/li>\n\n\n\n
    • D:<\/strong> 120.0.0.59<\/li>\n<\/ul>\n\n\n\n
      \n\n\n\n

      Explanation<\/strong><\/h3>\n\n\n\n

      VLSM allows us to allocate IPs efficiently by assigning each subnet a subnet mask that fits its needs. Instead of using a single fixed subnet mask<\/strong>, VLSM minimizes wastage<\/strong> of IP addresses.<\/p>\n\n\n\n

      Steps Used:<\/strong><\/h4>\n\n\n\n
        \n
      1. Determine Host Needs<\/strong>: Find the nearest power of 2 greater than or equal to the host count.<\/li>\n\n\n\n
      2. Assign Subnet Masks<\/strong>: The more hosts needed, the lower the subnet mask<\/strong> (e.g., \/27 for 30 hosts<\/strong>, \/28 for 12 hosts<\/strong>).<\/li>\n\n\n\n
      3. Allocate Networks Sequentially<\/strong>: Start from the lowest available address and move upwards.<\/li>\n\n\n\n
      4. Assign Broadcast & Usable Ranges<\/strong>: The first address is the network ID<\/strong>, the last is the broadcast<\/strong>, and the remaining are usable IPs<\/strong>.<\/li>\n<\/ol>\n\n\n\n

        By using VLSM, we ensure optimal address usage<\/strong> and scalability<\/strong>.<\/p>\n\n\n\n
