So I'm not a net wiz or anything, but I get the general idea behind IP addys and such. My question is about rDNS. I have read that turning off/disabling a reverse DNS for your computer can be a good thing and essentially make you more stealthy on the net. How does one go about doing this?

Also, at work, they IT dept has some how managed to "close" every single port and hide the UDP's. How does that get done?

Thanks!
