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: . 86299 IN SOA a.root-servers.net. nstld.verisign-grs.com. 2025060801 1800 900 604800 86400 dig -t ptr 8.8.8.8 ;; QUESTION SECTION: ;8.8.8.8.
