The arp -d command is used to delete a specified entry from the ARP (Address Resolution Protocol) table on a computer or network device. This command helps in clearing outdated or incorrect IP-to-MAC address mappings, which can assist in resolving connectivity issues or ensuring that the correct addresses are used in future communications. The command typically requires the specific IP address of the entry to be deleted.

What will happen if you execute the following command arp and ndashd?
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.
What command is used to view the ARP table?
To view the ARP table, you can use the command arp -a in the command prompt on Windows or arp on Unix/Linux systems. This command displays the IP addresses and their corresponding MAC addresses that the device has recently communicated with. Additionally, on Linux, you can also use ip neigh to view the ARP table.

How do you obtain mac address of HP Laserjet P2055dn?
Usually you don't need the MAC address directly - except perhaps to improve the documentation in a large network.If you know a device's IP address, you can do a pingcommand; before and after, compare the ARP cache - the one that shows assignments of IP addresses to MAC addresses. In Windows, the steps would be more or less like this:Open a command window arp -d * (this will delete the ARP cache)arp -a (this will show the ARP cache)ping ... (this will connect to the IP address you specify)arp -a (show the ARP cache again. Compare with the previous one.)Usually you don't need the MAC address directly - except perhaps to improve the documentation in a large network.

What is the arp command line?
The arp command line utility is used to view and manipulate the Address Resolution Protocol (ARP) cache, which maps IP addresses to MAC addresses on a local network. It allows users to display the current ARP entries, add or delete entries, and troubleshoot network connectivity issues. Typically, it can be run in various operating systems, including Windows, Linux, and macOS, with different options and syntax. For example, running arp -a displays the current ARP table on a system.
What does arp -s do in command prompt?

Arp -a
Which command will show the mac addresses of station connected to switch port?

The Windows command arp stands for address resolution protocol which simply transforms an IP address to its corresponding physical network address.And 'arp -a' simply lists down the physical network addresses of the network devices connected to the current PC.
