    Hi,

    Our default of net.inet6.ip6.v6only was off in 4.X, and was changed to
    on on 5.X to follow NetBSD's practice. This behavior on 5.X breaks
    RFC2553/3493, and the change was intentional from security
    consideration. But, NetBSD changed it off by default.
    How do you think our default of on?

    
    

    attached mail follows:

    The default value of ip6_v6only (sysctl net.inet6.ip6.v6only) has
    been changed. The new value brings us closer in line with current
    RFC-defined behavior and practices.

    Itojun still has significant concerns about the new default behavior.
    His concerns have been well-documented in
    ftp://ftp.itojun.org/pub/paper/draft-cmetz-v6ops-v4mapped-api-harmful-00.txt

    Best Regards,
    NetBSD OS PMC (core)
