I need a Powershell script to map drives based on IP addresses. Here are the requirements:

1) Create a script named drivemap.ps1

2) Create folders on your C drive root and name them after the departments

3) Have the script discover the IP address and convert to array of octet values

4) Check the first two octets for a match to make sure the IP address is correct for this building

5) In your script, have it map the associated drive letter to the corresponding folder on your C drive based on the discovered IP address third octet
