When I try scanning an Hamachi client’s 5.0.0.0/8 IP address, nmap states “doArp can only handle IPv4 addresses” and aborts. I know this is because Hamachi’s assignment of 5.0.0.0/8 IP addresses is unofficial, but it would be nice if the valid IPv4 address check could be disabled so Hamachi clients and other hosts with unofficially-assigned IP addresses could still be scanned. I searched for a solution/workaround but only found discussions about Hamachi’s unofficial IP address assignments, not any way to scan Hamachi clients. I do not think these details matter in this case, but I am currently using nmap v5.50 on Windows 7 Professional IA-32.
There must be something else going wrong, because I can ARP scan 5.0.0.0/8 with /sbin/ifconfig eth0:1 5.1.2.3 netmask 255.0.0.0 nmap -PR 5.0.0.0/8 --packet-trace Windows might be an issue. I'm not familiar with Hamachi, but if it creates a pseudo-interface, it probably won't work on Windows. (Because Windows lacks support for raw sockets, we can only do raw scans on Ethernet devices.) However, if that's the case, then the error message is misleading. Please send the output of "nmap --iflist". As a workaround you can try using the --unprivileged option to use plain TCP connect scan.
