The arp command is used to manipulate or display the Address Resolution Protocol (ARP) cache, which is a table that maps IP addresses to physical addresses (MAC addresses) on a network. The -s option is used to add a static ARP entry to the cache, which means that it will not expire or be overwritten by dynamic ARP entries.
The syntax for adding a static ARP entry is arp -s <IP address> <physical address>. Therefore, the command arp -s 192.168.1.63 60-36-DD-A6-C5-33 would add a static ARP entry for the IP address 192.168.1.63 and the physical address 60-36-DD-A6-C5-33 to the local cache of the attacker machine. This would allow the attacker machine to communicate with the target machine without relying on ARP requests or replies. The other commands are not valid or useful for establishing a static ARP entry.
