This is bad advice, because in DNS, ANY != ALL
If you query with qtype=any, and you ask a caching resolver, then it will return to you all the records that are in its cache at that time, which may or may not include the records you want.
In order to definitively get the A as well as the AAAA records, one needs to ask for them specifically:
nslookup -type=AAAA www.example.com nslookup -type=A www.example.com
This makes a cache explicitly look up those types of records if it doesn't already have them.
Thanks this brings light in the dark ...
