Question

Accepted Answer

⚹ To find the first usable host address for the Seattle LAN using VLSM, we need to follow these steps: ⚹ ⚹ **Step 1: Determine the subnet requirements for each location.** ⚹ ‖ ▪ ⋮ Seattle: 15 hosts ‖ ‖ ▪ ⋮ Denver: 15 hosts ‖ ‖ ▪ ⋮ Phoenix: 100 hosts ‖ ⚹ **Step 2: Calculate the subnet mask for each location.** ⚹ ‖ ▪ ⋮ For 15 hosts, we need at least 16 IP addresses (2^4 = 16). The subnet mask will be /28 (255.255.255.240). ‖ ‖ ▪ ⋮ For 100 hosts, we need at least 128 IP addresses (2^7 = 128). The subnet mask will be /25 (255.255.255.128). ‖ ⚹ **Step 3: Assign subnets to each location starting from the lowest address.** ⚹ ‖ ▪ ⋮ Phoenix: 199.40.254.0/25 (usable IP range: 199.40.254.1 - 199.40.254.126) ‖ ‖ ▪ ⋮ Seattle: 199.40.254.128/28 (usable IP range: 199.40.254.129 - 199.40.254.142) ‖ ‖ ▪ ⋮ Denver: 199.40.254.144/28 (usable IP range: 199.40.254.145 - 199.40.254.158) ‖ ⚹ **Step 4: Identify the first usable host address for the Seattle LAN.** ⚹ ‖ ▪ ⋮ The first usable host address for the Seattle LAN is 199.40.254.129. ‖ ⚹ Therefore, the first usable host address for the Seattle LAN is ⚹ **199.40.254.129** ⚹.⚹
