Click Launch Console, and then click Yes. So to get the hostname of 10.11.12.13, we say to DNS "Give me the PTR record for 13.12.11.10.in-addr.arpa." Under Options, click Console Redirection. The IP address in the PTR record is reversed. However, there is no obligation to store PTR records so they may not be present, in which case the lookup will fail. For each IP address, there is a PTR record in which is stored the associated hostname. In DNS this is achieved through PTR records. Once you have the IP address, you are relying on a name resolution service to do a reverse lookup and return a hostname that is associated with an IP. You can trigger arp requests manually by pinging every IP on the network, or using a utility like nmap to do them all in one go. prepend the link-local prefix: fe80:: 5074. replace first octet with newly calculated one: 50 74:f2ff:feb1:a87f. convert octet back to hexadecimal: 01010000 -> 50. convert the first octet from hexadecimal to binary: 52 -> 01010010. In order for this to work, both devices must be on the same layer 2 network - the same switch/vlan. reformat to IPv6 notation 5274:f2ff:feb1:a87f. In order to populate that list, the machine will have had to at some point issued an arp request, saying "who has IP x.x.x.x" - the owner will reply and upon receipt, the arp table will be populated.

As per the question, arp -a will list the MAC addresses and corresponding IP addresses.

This means that you need access to a device that has the IP address associated with the MAC. If you start with a MAC address, you first need to get the IP address.
