System Stealth Mode

Check to see if your router is operating in stealth mode for computer security. (My results below)

Your Internet connection has no Reverse DNS
Many Internet connection IP addresses are associated with a DNS machine name. (But yours is not.) The presence of "Reverse DNS", which allows the machine name to be retrieved from the IP address, can represent a privacy and possible security concern for Internet consumers since it may uniquely and persistently identify your Internet account � and therefore you � and may disclose other information, such as your geographic location.
When present, reverse DNS is supported by Internet service providers. But no such lookups are possible with your current Internet connection address (2.39.138.109). That's generally a good thing. (My IP Address has been changed for security)

Your system has achieved a perfect "TruStealth" rating. Not a single packet � solicited or otherwise � was received from your system as a result of our security probing tests. Your system ignored and refused to reply to repeated Pings (ICMP Echo Requests). From the standpoint of the passing probes of any hacker, this machine does not exist on the Internet. Some questionable personal security systems expose their users by attempting to "counter-probe the prober", thus revealing themselves. But your system wisely remained silent in every way. Very nice.

Grc has some useful tools, but the scaremongering means I very rarely send people there

I've always used ShieldsUP! Never had an issue with it.

This crops up every so often!!! ;(
"Your system has achieved a perfect "TruStealth" rating....." which is absolute rubbish as I know for a fact that a port in use for FTP was wide open when the test was run. It continually fails to register this fact.

It all works, it's just the recommendations are a bit misguided. I fail the test, and in some respects I wish more people would, because I think enabling ICMP is important and can be very useful in diagnostic when it comes to broadband faults..
