How to do IP Subnetting part 2?



To determine how many subnets can be created from the 192.168.0.0/24 network while accommodating 48 hosts in each subnet, let's follow these steps:

  1. Calculate the number of host bits needed:

    • 48 hosts + 2 (network address and broadcast address) = 50 total addresses needed

    • The smallest power of 2 that can accommodate 50 is 64 (2^6)

    • So we need 6 host bits


  3. Determine the subnet mask:

    • Original network is /24, so we have 8 bits available in the last octet

    • We need 6 bits for hosts, so we can use 2 bits for subnetting

    • New subnet mask will be /26 (24 + 2)


  5. Calculate the number of subnets:

    • With 2 bits for subnetting, we can create 2^2 = 4 subnets


Therefore, the company can create 4 subnets from the 192.168.0.0/24 network, each accommodating 48 hosts.

The subnets will be:

  1. 192.168.0.0/26 (usable range: 192.168.0.1 - 192.168.0.62)

  2. 192.168.0.64/26 (usable range: 192.168.0.65 - 192.168.0.126)

  3. 192.168.0.128/26 (usable range: 192.168.0.129 - 192.168.0.190)

  4. 192.168.0.192/26 (usable range: 192.168.0.193 - 192.168.0.254)

Each subnet will have 62 usable host addresses, which is more than enough for the required 48 hosts per subnet.
