Re: [v6ops] draft-pauly-v6ops-happy-eyeballs-update-01

May be this is related to the US ESTA payment page, as it is broken since several years ago (unless they sorted it out after I paid my renewal about 5 months ago), and nobody is paying attention or even responding to the emails to their contacts …

HE doesn’t even solve their problem, as it is related to PMTUD broken, so only if you know this and are an engineer know how to disable IPv6 to be able to access the payment … Nice example from a government :-(

    Just a comment following up on Jordi's Mic comment
    Jordi said there was an issue with HE hiding IPv6 issues.

    David's response was something along the lines of "deploy ipv6-only".  I did not really understand this.

    When folks deploy ipv6-only, they find they are all alone with a broken ipv6 scenarios that work on all their competitors IPv4-only networks and HE dual-stack networks.

    Also, friendly reminder that Dan Wing catalogs a subset of the websites that fail on ipv6-only http://www.employees.org/~dwing/aaaa-stats/

    And, my customers still complain about www.fra.dot.gov <http://www.fra.dot.gov> ... this works for everyone but me... because of HE...and I am already on IPv6-only ... and nobody will fix it.  This issues has been known by the USG DOT for over 3 months, noted to NANOG, nobody cares to fix it.

    So, perhaps there is room in the I-D for including NAT64 synthesized address candidate set.  Meaning the HE algo on an IPv6-only host would include the set of available native IPv6 answers as well as a 500ms timer for attempting an A query with using whatever mechanism is available to the host for relaying IPv4 packets across an IPv6 only network (RFC6877, Bump in API, ...) 

    Without this, IPv6-only networks are at a painful disadvantage since IPv6 must be perfect while every other scenario has HE to mask brokenness.
