HOWTO: DNS Override for AAAA results only to circumvent IPv6 black hole



  • Hi Everyone,

    I'm looking for some instruction on setting up the DNS Forwarder so that it only replies with A queries for a particular domain.  There's an IPv6 black-hole on Microsoft Office Web Apps via SkyDrive which has been around for a few months now.  It's completely fine on IPv4 but times out over v6.

    Therefore I'd like to configure the forwarder to actually NOT reply at all to AAAA queries so that the client falls back to querying for A records.  Is this even possible?

    Any and all help greatly appreciated.



  • Quick update after reading the dnsmaq man.

    Both custom options

    --alias=2a01:111:f406:1006::81,65.55.18.81
    

    and

    --bogus-nxdomain=2a01:111:f406:1006::81
    

    Generate an error when trying to save:

    The following input errors were detected:

    Try without the "–"  ;)    ???

    
    alias=2a01:111:f406:1006::81,65.55.18.81
    
    
    
    bogus-nxdomain=2a01:111:f406:1006::81
