The command arp -d
is used to delete an entry from the ARP (Address Resolution Protocol) cache on a networked device. Executing this command will remove the specified IP-to-MAC address mapping, which may disrupt communication with that device until the entry is rebuilt through ARP requests. If no specific entry is provided, it may lead to the deletion of all ARP entries, necessitating the re-establishment of connections. However, the actual output and behavior can depend on the specific operating system and its implementation of the ARP command.
