arp: Delete a specific entry.
$ arp -d ${address}
try on your machine
The command "arp -d ${address}" is used to delete an entry from the ARP (Address Resolution Protocol) cache table.
- "arp" is the command to manage and display the ARP cache on a system.
- "-d" is an option used to delete an entry from the ARP cache.
- "${address}" is a placeholder for the specific IP address or hostname you want to remove from the ARP cache.
The ARP cache is a table that maps IP addresses to MAC (Media Access Control) addresses on a local network. When a device needs to communicate with another device on the same network, it uses ARP to find the MAC address corresponding to the IP address of the destination device.
By running "arp -d ${address}", you can delete a specific entry from the ARP cache. This can be useful in situations where you want to refresh or clear the cache, or when there is an issue with a particular entry causing network communication problems.
