There are some domains that are already known to be very broken when you
have a mixed IPv4 and IPv6 network, and can be added to a blacklist so
that they'll only use IPv4.  You've found one of them.

Long ago I put a null entry into my DNS server for a few domains,
including that one.  It's one of my favourite web browser error messages
(being unable to find some adserver, somewhere).  ;-)
