Il s'agit d'un nombre de 32 bits utilis\u00e9 pour diviser une adresse IP en deux parties, l'adresse r\u00e9seau et l'adresse h\u00f4te. Le masque de sous-r\u00e9seau est utilis\u00e9 conjointement avec l'adresse IP pour d\u00e9terminer quelle partie de l'adresse IP est utilis\u00e9e pour identifier le r\u00e9seau et quelle partie est utilis\u00e9e pour identifier l'h\u00f4te.<\/p>\n<p>Le masque de sous-r\u00e9seau est utilis\u00e9 pour d\u00e9terminer la taille du r\u00e9seau, ce qui est important pour le routage et la communication entre les appareils.

Le masque de sous-r\u00e9seau est repr\u00e9sent\u00e9 en notation d\u00e9cimale point\u00e9e, c'est-\u00e0-dire une s\u00e9rie de quatre nombres s\u00e9par\u00e9s par des points. Chaque chiffre repr\u00e9sente 8 bits du masque de sous-r\u00e9seau et les chiffres sont compris entre 0 et 255.<\/p>\n<p>Le masque de sous-r\u00e9seau est utilis\u00e9 conjointement avec l'adresse IP pour d\u00e9terminer l'adresse r\u00e9seau. L'adresse r\u00e9seau est la partie de l'adresse IP qui identifie le r\u00e9seau. L'adresse de l'h\u00f4te est la partie de l'adresse IP qui identifie l'appareil individuel sur le r\u00e9seau. Le masque de sous-r\u00e9seau est utilis\u00e9 pour d\u00e9terminer quelle partie de l'adresse IP est utilis\u00e9e pour identifier le r\u00e9seau et quelle partie est utilis\u00e9e pour identifier l'h\u00f4te.<\/p>\n<p>Le masque de sous-r\u00e9seau est un \u00e9l\u00e9ment important du r\u00e9seau IP.
