See http://people.freebsd.org/~bms/dump/mcastlist/ for the original code (harti@ submitted most of the kernel bits). I didn't specifically set out to test getifmaddrs(3) with AF_INET6 addresses when I wrote it, but I seem to recall that it should work with them, from testing. If not, please feel free to submit a PR with a patch. Thanks, BMS
