However, the multicast UDP and TCP packets can be used to do high efficient
port scanning in local link. The scan type of 8-udp dns is a good example.

I'm sorry that I'm afraid the DNS service is an exception. The TCP packet
multicast to ff02::1 couldn't probe open ports since TCP sockets generally
don't join the FF02::1 group.
The multicast TCP SYN and TCP ACK of alive6 are useless in my tests.
