Re: [MBONED] Adoption of Multicast Filtering Practices draft

In general, I don't have any objections. But I did object to this:

   As a general principle, multicast sourced from private address ranges
   [RFC1918] or from 169.254.0.0/16, 192.0.2.0/24 or 127.0.0.0/8 should
   be dropped, regardless of the multicast destination.

It's the "from private address ranges" that bothers me. It is not so far-fetched that an organizational network would be using at least some RFC 1918 addresses, and that these would be legitimate sources of IP multicasts.

Especially these days, when public IPv4 addresses have essentially run out.
