Fwd: New Version Notification for draft-arifumi-6man-addr-select-conflict-00

2009-07-09 Thread Arifumi Matsumoto
All, I submitted a new individual draft regarding address selection policy conflicts. This document tries to speculate what kind of conflicts we will have, and how we can address them. This document is not based on any specific proposed address selection mechanisms. I'd like to have comments

The DNS64 has to stuff the IPv4 bits somewhere in the IPv6 bits. Although it's simpler to do that at a 32 bit boundary (and a 16 bit boundary has checksumming advantages), as far as I know all of this happens in software and can be handled fast enough even if the rules get more complex to

There are about 3.7 billion usable IPv4 addresses. Do you really want to make a table that big, when the IPv6 host is going to expose everything to every IPv6 node it talks to anyway? Very few hosts speak to 3.7 billion peers at the same time. Those who do probably have dual stack. In most
