MAC addresses are not normally used for network identification outside of their segment. In addition, none of the higher level protocols in common use contain the MAC address in their headers. >e.g.: can I get the MAC from a normal, public IP? > >There is no solution for this? 1. See if they are mis-advertising their IPv6 auto-configuration address as a public IPv6 address, perhaps through an AAAA record. 2. Traceroute the system. The last machine in the traceroute that is not the target probably on the same network segment. Crack that machine.[*] Verify it is on the same network segment. If not, start again with a traceroute from this system. If so, you can use ARP directly, tcpdump -e, some versions of ping, or nmap to determine the MAC address of a computer on the same segment. * That would most likely be illegal. Don't to it.
