How does iptables determine which packets are multicast?

  • 772

Are packets assumed to be multicast solely based on their ip address? I've been looking at the RFC 1112 and a quick scan doesn't appear to indicate any other flags on the ip packet.

    The IP multicast address ranges are defined in the standard. You have a look at them here and here.
