Your query wasn't specific, though, you asked for ANY record and you got
one. Here's what my dnscache gives me:

jester at koala:~$ dnsname 65.39.70.155
cd.dvdrestore.com

Or:

jester at koala:~$ dnsqr ptr 155.70.39.65.in-addr.arpa
12 155.70.39.65.in-addr.arpa:
11994 bytes, 1+459+0+0 records, response, noerror
