+# Retrieve the Preferred Server Based on the IP Address
+
+![GetMyPreferedServer Screenshot](https://blog.wuibaille.fr/wp-content/uploads/2024/04/GetMyPreferedServer.png)
+
+This script allows you to **identify the preferred server** for a device, based on its **IP address**, by querying a central SQL database.
+
+---
+
+## 🔧 Configuration
+
+Before using the script, update the following lines with your SQL connection details:
+
+```powershell
+$dataSource = "InstanceSQL"
+$user       = "SQLAccount"
+$PassSQL    = "SQLPassword"
+$database   = "DatabaseName"
+```
+
+Make sure the account has permission to query the relevant table containing IP/server associations
