Practical Subnetting $10$

Based on the information in the graphic shown, design a network addressing scheme that will supply the minimum number of subnets, and allow enough extra subnets and hosts for $110\%$ growth in all areas. Circle each subnet on the graphic and answer the questions below.

Address class

Custom subnet mask

Minimum number of subnets needed

Extra subnets required for $110\%$ growth

$($Round up to the next whole number$)$

Total number of subnets needed

Number of host addresses in the largest subnet group

Number of addresses needed for $110\%$ growth in the largest subnet

$($Round up to the next whole number$)$

Total number of address needed for the largest subnet $=$

Start with the first subnet and arrange your sub$-$networks from the largest group to the smallest.
