Except that if an implementation supports the
SCTP_I_WANT_MAPPED_V4_ADDR
And this is turned OFF
Then you would get a mix of V4 and V6 addresses (what Kacheong hates)..
which is why it is vague...
For some O/S's (such as Kacheongs) you cannto turn
SCTP_I_WANT_MAPPED_V4_ADDR
Off... and thats fine.. then your statements above would be completely
true..
For other OS's.. aka BSD.. you CAN disable that option so you would
get back a mix..
