Hi,
Just pointing out to other responding to this thread that I was referring to
the *query* response times, I said nothing about ICMP which is perfectly fine.
So please stop responding with ping response times already :-)
No, pfSense does not set these per default, they are in wide use because these
are part of the Google DNS whitelist for V6 records.

And a similar mistake I see others respond too as well, this is another domain
with just a IPv4 record. That was not really what I was complaining about but I
was not specific enough in my email
When requesting the DNS for the hostname with a Quad A the story is entirely
different!
Try www.pfsense.com or www.didi.nl
Those will definitely hit the issue, otherwise one can always use Nanog.org
like below.
