May be a possibility that the slaac script is not checking the
reachability of scanned nodes.
This is common to all targets scripts. I have seen phantom addresses
come from the slaac script on Windows too. Scripts should not verify
addresses themselves. Nmap will do its own more reliable ND
of the added addresses. ICMPv6 echo is less reliable than ND.
IN case of dual stack <ipv4 and ipv6 togather> nmap can be used to scan
ipv4 addresses in the network, and henceforth use icmpv6 node Info
messages<type 139> to get their respective ipv6 addresses.
The ipv6-node-info script does this. (Actually it gives you IPv4
addresses when you know the IPv4 address; is it possible to go the other
what i was thinking is to send a NI query of code 2<data ipv4 address> to
all-node multicast address <ff02::1> putting ipv4 scanned addresses. This
may result in nodes responding with required information.
also it would be interesting to see what happens if a noop query is sent
to all node multicast.
