  • IPv4 broadcast works on Windows systems
  • IPv6 multicast client is known to work on Solaris
  • IPv6 multicast client is known to work on FreeBSD
  • IPv6 multicast server is known to work on FreeBSD
  • IPv4 multicast works on Windows systems with authentication disabled
  • IPv4 multicast fails on Windows systems with authentication enabled
