not horror, just had to back off.
small site. so public servers provide multiple and diverse services.
if a hostname has a v6 address, then all services must be v6 capable
because clients do not retry the A record.
and, as someone pointed out earlier, hostname hacks do not work; a
referring link can not choose to yield v6.foo as opposed to foo
depending on the abilities of the link follower.
when i have copious spare time, i will try to sort services by v6
abilities and have another go. but spare time is like spare money these
days, sigh.
