Q1: 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 20% growth in all areas without using VLSM. Circle each subnet on the graphic and answer the questions below. IP Address 20.0.0.0 SO/O/O SO/0/1 F 0/O Router SO/O/1 F O/O Dallas 150 Hosts New York 325 Hosts Washington D.C 220 Hosts Address class Custom subnet mask Minimum number of subnets needed Extra subnets required for 20% 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 20% 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 IP address range for New York IP address range for Washington D. C. IP address range for Dallas IP address range for Router A to Router B serial connection IP address range for Router A to Router C serial connection
