So, does that mean you retract your earlier slam at dnsreport for the
"missing glue" thing specifically with goya.com.au?

dnsreport was also correct....and it didn't cost $500....it cost 0$

Indeed. However, most admins would quickly figure that out after
seeing the dnsreport warning flag. dnsreport would have been a help,
in this case (as was DNS Expert).

Now that Macs are becoming more and more of a 2nd class citizen with
Men and Mice (first platform to get products dropped and last
platform to get new products [4.6, for example]). I can't say, as I
don't use it much anymore since there's no OS X version (I don't even
install Classic on my boxes) and I don't fire up Windows often.

The fact that you make such a statement is as telling as it is
pathetic. I'm sorry you feel that this is some sort of contest. I
doubt anybody on this list really feels they can beat any miceandmen
poster at DNS issues and has any desire to even try.

This is specifically about your continued unsupported attacks on a
valuable free service and your insinuation that people who use that
service are either misled or newbies. You don't need to denigrate the
tools which have served your paying customers well for us to realize
that no such tool is as good as expert analysis by a schooled human
such as yourself. We know that. We also know you know your
stuff...but unless you're offering your zone analysis skills pro bono
to all, we'll take what we can get. And a combo of our dns experience
(inferior to yours, I'm, sure), our own CLI tools, and tools like
dnsreport...we are much better off than w/o such a free service.

And the harm that comes from this is....?

And dnsreport would lead one down the path to detecting that error as well.

Again with the contest. I have not accused DNS Expert of screwing up.
I have pointed out that it reported the same sort of errors you
faulted dnsreport for reporting with the zone in question
(goya.au.com).


>And my complaint about the "missing glue" BS from DNSReport remains valid.


A valid opinion yes. I for one, do not mind seeing such warnings and
evaluating them individually on their merits. In the case of the zone
we are talking about, the information provided by dnsreport was
useful and valid.
