+Function Reset-HawkEnvironment {
+    <#
+    .SYNOPSIS
+        Resets all Hawk-related variables to allow for a fresh instance.
+
+    .DESCRIPTION
+        This function removes all global variables used by Hawk, including the main Hawk object,
+        IP location cache, and Microsoft IP list. This allows you to start fresh with Hawk
+        without needing to close and reopen your PowerShell window.
+
+        Variables removed:
+        - $Hawk (Main configuration object)
+        - $IPlocationCache (IP geolocation cache)
+        - $MSFTIPList (Microsoft IP address list)
+        - $HawkAppData (Application data)
+
+    .EXAMPLE
+        Reset-HawkEnvironment
+        
+        Removes all Hawk-related variables and confirms when ready for a fresh start.
+
+    .EXAMPLE
+        Reset-HawkEnvironment -Verbose
+        
+        Removes all Hawk-related variables with detailed progress messages.
+
+    .EXAMPLE
+        Reset-HawkEnvironment -WhatIf
+        
+        Shows what variables would be removed without actually removing them.
