Submission + - PenTeleData Lists Subscriber Names in Reverse DNS
jpiratefish writes: Most people know that they can be identified when they browse to some degree — and if you're careful, nothing short of a subpoena will get your actual name — but not if you use PenTeleData in Eastern Pennsylvania. They're putting business and subscriber names into their reverse DNS, in direct violation of their privacy agreements (http://www.penteledata.net/support/aup.shtml and http://www.ptd.net/tiki-index.php?page=Residential+Policies). Some juicy examples include these:
24.229.69.2 : cpe-static-jpjayassoc-rtr.cmts.all.ptd.net
24.229.69.3 : cpe-wifi-subwaytilghman-145.2.1-ap.cmts.all.ptd.net
24.229.69.4 : cpe-static-aestheticsurgery-rtr.cmts.all.ptd.net
24.229.69.7 : cpe-static-thecontigrpmdm2-rtr-cmts.all.ptd.net
24.229.69.8 : cpe-static-apa612wlindenst-rtr.cmts.all2.ptd.net
24.229.69.10 : cpe-static-questlvfamily-rtr.cmts.tv2.ptd.net
24.229.69.12 : cpe-static-ramadainnkiosk-rtr.cmts.all.ptd.net
24.229.69.15 : cpe-static-cntyoflehighgovtcntr-rtr.cmts.all.ptd.net
24.229.69.51 : cpe-static-westendpharmacy-rtr.cmts.all2.ptd.net
24.229.69.52 : cpe-static-bnaibrithapartments-rtr.cmts.all2.ptd.net
24.229.69.55 : cpe-static-adultmedgeriatics-rtr.cmts.all2.ptd.net
24.229.69.56 : cpe-static-cysticfibrosis-rtr.cmts.tv2.ptd.net
24.229.69.57 : cpe-static-stanleywest-rtr.cmts.all2.ptd.net
24.229.69.58 : cpe-static-panylentzengineering-rtr.cmts.all2.ptd.net
24.229.69.59 : cpe-static-drhabig-rtr.cmts.all2.ptd.net
And that's just one little bit of their 24.229.0.0/16 network (16,384 hosts)....
I can only imagine that these folks are subjected to tons more targeted marketing, and identity theft, than the rest of us. If you use PenTeleData, you should do a reverse lookup on yourself (suggested link — http://ipchicken.com/ and see if your name is listed.
