I should have pointed out, that the stack implements both IPv4/IPv6,
but all addressess are stored in IPv6 format, and all processing is
uniform for both IPv4 and IPv6.
Internally, IPv4 is using IPv4 mapped addresses. Thus, as far as I'm
concerned, 224.x.x.x is same as ::ffff:224.x.x.x. I don't see any
reason to differentiate between them.
When I say I treat ::ffff:224.x.x.x as multicast, I'm just
implementing IPv4 multicast as I should. The "non-conformant" part was
whether I should accept IPv4 multicast operations that use the IPv6
multicast API (and was tentatively considering it a "feature" :)
