My ISP just added reverse DNS to my ADSL line. Shields Up brought it to my attention and I asked the ISP about it. They say I shouldn't be concerned. Shields Up says that any Web site I long on to can recognized my computer without setting a cookie, as least as far as I understand it. I try to keep most if not all cookies off of my machine. Maybe I'm paranoid.
What does conventional wisdom say about reverse DNS? I've run without it for a long time and haven't seen any bad effects because of the lack thereof.
Should I insist they disable it?
Thank you very much.
