Holen Sie sich eine eindeutige Client-ID von Benutzern in meinem WLAN

Ich habe eine Batchdatei geschrieben, um festzustellen, ob ein neuer Client mit meinem lokalen WLAN verbunden ist. Die gesamte Batchdatei funktioniert einwandfrei.

Das Skript erkennt neue verbundene WLAN-Clients und zeigt deren IP-Adresse und MAC an.

Die Sache ist, ich möchte gefälschte MAC-Adressen erkennen oder Clients auf andere Weise identifizieren, so dass ich feststellen kann, ob sie gefälscht sind oder nicht, indem ich sie mit vorherigen Verbindungen vergleicht.

Googled ein Haufen, aber alles, was ich bekomme, ist Software; Ich brauche eine Möglichkeit, dies in einer Batchdatei zu tun.

Weiß jemand, wie man damit anfängt?

Hier ist das Skript: (ignorieren Sie die :: Kommentare, sie sind auf Niederländisch)
