i'd imagine they prolly have software that listens for pings, and tells the computer to not return them... not exactly sure how a ping works or i could prolly like write a piece of software to do that
get a firewall that allows you to block icmp.
It normally requires kernel support to do things like that on any OS I've heard of. On Windows, programs like ZoneAlarm just register in as services and take control of the data stream.Quote:

But yeah, blocking the specific ping ICMP replies. Be careful though, if you block too much the other routing to your machine stops working as the ISP's routers decide you're not there.
a long long time ago, when everyone wanted to test their internet connection, they pinged the first thing they could think of. most of the time that was microsoft. so ping www.microsoft.com was what they used.
ms decided they didn't want their precious (and copious amounts of) bandwidth consumed by idiots testing their internet connection. so they disabled icmp
now we ping yahoo.
I used to ping MS. Now I ping the BBC :)
