Well, the funny thing is... people think that not responding to ping makes them invisible and the "hacker" will think there's no computer connected.

- If there was no computer with given address connected, they'd get ICMP Destination Unreachable (ICMP Type 3) with one of the codes (such as 0 - net unreachable, 1 - host unreachable ... etc).

- Whey they simply drop those packets (full stealth FTW), they get a request time-out instead, so the router is clearly suggesting that there actually is a computer out there with such address, but it's dropping the ICMP packets...

And then the worries end on their own.

Yeah, that's a much better solution to these security problems...
