Nslookup and regex filter with querytype=AAAA

[mibere]

If there is a regex blacklist filter

abc;querytype=AAAA

the command nslookup -query=AAAA abc on Windows returns

Address: ::

nslookup -query=A abc returns

Address: 1.2.3.4

But, is it correct that nslookup abc returns

Address: ::

I had the expectation that the IPv4 address would be returned.

I can't reproduce that observation on my system, e.g. when regex blocking heise.de;querytype=AAAA:

$ nslookup heise.de
Server:		192.168.1.53
Address:	192.168.1.53#53

Non-authoritative answer:
Name:	heise.de
Address: 193.99.144.80
Name:	heise.de
Address: ::

What system did you run that nslookup from? And when you run it, would requests for A as well as AAAA records register in Pi-hole's Query Log?
