Part 1
You are hired to design an IP addressing scheme for five departments that will provide security and access to the Internet. Each department requires between 1,500 - 2,000 IP addresses. The company will have 2,000 IP addresses accessing the Internet at any given time.
Start by designing an IP addressing scheme, then, for each department, assign an IP address range and specify the subnet mask.

Departments IP address range Subnet Mask
Department A
Department B
Department C
Department D
Department E 

Next, determine which NAT method you would implement for this scenario. The plan should have all of the appropriate NAT commands and the verification commands used to prove the accuracy of your configuration. 
Your paper should reflect the correct configuration commands and the appropriate show commands to verify your work. prepare a 1-2 page paper listing the plan to present to your superior, who has a technical background, that details your plan and your timeline for  implementation. Include your proposed network changes and a two-sentence outage message that will be sent by a broadcast email to the affected users, who like to complain when the network is not available. Also include other concerns about this change and other departments that should potentially be contacted before the change.
