Subject: rfc3484-bis issue 1: deprecated prefixes

Hi,

The authors of rfc3484-bis would like to solicit feedback on three open issues, to help shape a (hopefully) final update before the cut-off on 11th July.

The first issue is which deprecated prefixes to include in the new default policy table.  As of -03, the 3ffe::/16 prefix has been removed.  Should the site-local and IPv4-compatible prefixes also be removed from the table?

We also note that there is discussion about the future of 6to4, and thus of the 2002::/16 prefix.  Since draft-ietf-v6ops-6to4-advisory-02 cites 3484-bis as a tool to mitigate against the bad effects of 6to4, it seems prudent to leave the 6to4 prefix in the table to allow for existing 6to4 implementations. Sites wishing to prefer 6to4 to IPv4 can adjust their policy table manually or using the proposed DHCPv6 option.

Comments please.

Tim
