Well yes but the record is sometimes returned as an A/AAAA so I'm being
generic to ask IP to a record of any kind.
Even if I ask directly for an A record or a PTR record I still get
something if there is something to return:
dig -t a 8.8.8.8
;; QUESTION SECTION:
;8.8.8.8. IN A
;; AUTHORITY SECTION:

dig -t ptr 8.8.8.8

It can be a PTR, an A/AAAA, an MX, doesn't matter to me.
You said "rDNS lookup". That implies PTR.
