@delta407 No. The routing semantics need to be tweaked (see https://cr.yp.to/djbdns/ipv6mess.html), and then need to be made mandatory for IPv6 software.

Deep confusion in https://blog.sesse.net/blog/tech/2016-01-06-20-54_ipv6_non_alternatives_djbs_article_13_years_later.html doesn't manage to hide the core issue: "The _single_ benefit is that they won't have to renumber."

Easy IPv6 software+spec changes today, adding the critical IPv4-addresses-work-without-renumbering feature, would still have huge benefits.

@hashbreaker Every IPv4 addr has a 2002:xxxx:xxxx::/48 6to4 prefix already. Many routers can encap in hardware. Is this what you're needing?
