🔎 L’ARP (Address Resolution Protocol) est un protocole qui fait le lien entre les adresses IP (couche réseau) et les adresses MAC (couche liaison) des appareils sur un réseau. Il permet la communication entre les couches 2 et 3 du modèle OSI.
📩 Messages ARP
– Requête ARP : demande l’adresse MAC associée à une adresse IP.
– Réponse ARP : Fournit l’adresse MAC correspondante.🖥 Adresses dans ARP
– Adresse matérielle source (MAC) : l’adresse MAC de l’expéditeur.
– Adresse Protocole Source (IP) : l’adresse IP de l’expéditeur.
– Adresse matérielle cible (MAC) : l’adresse MAC du destinataire (généralement inconnue lors de la requête).
– Adresse protocole cible (IP) : l’adresse IP du destinataire.🗄 Table ARP (Cache ARP)
La table ARP stocke les correspondances entre les adresses IP et MAC pour accélérer les futures communications.Commandes de base (Windows/Linux) :
“`bash
# Afficher la table ARP
arp-a# Ajouter une entrée ARP statique
arp -s 192.168.1. 10 00-1 A-2 B-3 C-4 D-5 ESupprimer une entrée ARP
arp -d 192.168.1. 10
“`✨ Conclusion :
ARP est essentiel pour le bon fonctionnement de votre réseau local. Une bonne gestion de la table ARP garantit une communication efficace et sécurisée entre vos appareils ! 💼🔧hashtag #Réseau hashtag #ARP hashtag #Technologie hashtag #IT hashtag #Sécurité hashtag #Networking
