[dns-operations] why does that domain resolve?

[Adam David]

I would concur, dnschecker shows incorrect information. I feel that it
could be their recursive dns failing to provide correct responses, or a
coding error?

Either way, I wouldn't use it.

When I check using "dig" all records show correctly.

Using mxtoolbox.com is another option if you are not familiar with "dig"
and the applicable RFCs.
