"dig -x 8.8.8.8" is what you're after. :) The -x says "reverse the dotted elements, append '.in-addr.arpa.' and set QTYPE to PTR." Unlike most dig command line elements, order matters: the "-x" must come immediately before the IP address being queried. Note that it's not smart. ANY string of dotted elements will be handled in this way, not just an IPv4 address. Agreed that nslookup has a lower learning curve, and some folks prefer its interactive mode. To me that's not worth the risk of getting wrong/misleading data. > [harry@srv-rhsoft:~]$ nslookup 8.8.8.8 > Server: 127.0.0.1 > Address: 127.0.0.1#53 > > Non-authoritative answer: > > 8.8.8.8.in-addr.arpa name = google-public-dns-a.google.com. -- http://rob0.nodns4.us/ Offlist GMX mail is seen only if "/dev/rob0" is in the Subject:
