Abstract

La présente demande appartient au domaine technique de la communication et divulgue un procédé d'attribution d'adresse IP, un dispositif et un support de stockage lisible. Le procédé comprend les étapes suivantes : un premier terminal envoie un premier message de demande à un premier élément de réseau, le premier message de demande étant utilisé pour demander l'attribution d'une adresse IP à un second terminal ; le premier terminal reçoit une première adresse IP du premier élément de réseau, la première adresse IP étant une adresse IP attribuée au second terminal ; et le premier terminal envoie une seconde adresse IP au second terminal selon la première adresse IP.
