Is there any way that you can find all the IP addresses within a LAN without assigning a IP address to you NIC?

I know most of the tools like angryipscanner, arp-scan, nmap and others can mostly identify the hosts within a particular IP range and with your NIC assigned with an IP address.

What if I wanted to find all the addresses within a LAN just by plugging my NIC to a switch and using for example ARP for all the nodes connected to the network to reply an arp request with their IP address and MAC address using only my NICs MAC address.

No, that's not possible. You cannot use the TCP/IP tools without an IP address. That would be like connecting to a network without a network card.

What would be possible is test MAC address to MAC address communication, but both NICs would have to have similar firmware loaded and knowledge of each other's MAC address to be able to do this (Intel cards used to be able to do this 20 years ago).

Sorry to be the harbinger of bad news...
