If someone is going to make .internal resolve on their network, they're going 
to have to use
some kind of kludge to serve the records.  So what we are really debating is 
what kind of
kludge we think will break less badly.

On my network, everything uses the local DNS cache, nothing does endpoint 
DNSSEC validation,
so if the cache says the results are OK, they're OK.  I realize that other 
people may set
up their systems differently, but in all of years we've been futzing with 
DNSSEC I have not
seen even a vague agreement on how one might best provide results that are 
different from
what you get by delegation from the root and make it work with DNSSEC.

So I think we should not say anything about it, because whatever we say will be 
wrong at
least half the time.

R's,
John
