VBA EXCEL : Insertion de l'adresse IP

Bonjour le Forum,

J'ai trouvé un code qui me permettait de récupérer l'adresse IP de la machine (code ci dessous) . Je voudrais insérer l'adresse IP de chaque utilisateur ainsi que la date et l'heure d'ouverture du fichier sur ma feuil1. (fichier partagé sur un serveur).

Code:

LocalIPAddress = sIPAddr
 
End Function

En mettant LocalIPAddress = Range("A1") sur le workbook open l'adresse IP s’insère sur la cellule "A1" (il me manque la date et l'heure sur la cellule "B1"). je veux lorsqu'il s'agit d'une nouvelle adresse IP(nouveau utilisateur), il y'aura insertion de cette nouvelle adresse IP non pas sur "A1" mais sur la cellule ("A2") et la date sur la cellule "B2" et ainsi de suite.. et si l'adresse IP existe déjà sur la colonne A (ancien utilisateur) , il suffit uniquement de changer l'heure sur la même ligne sur la colonne B .

Merci d'avance.
