I did a firewall test online and although it found no open ports it was able to see my natted(the ones that always start 192.xx.xxx) ip and the site said to truly be secure I need to hide it. they also said that people can monitor what you do if they can see that. I don't need that..

anyway, I have a d-link router (DI-604) so how can I configure it to hide this?

I never heard that it's bad that your IP is visible. And I really doubt someone can see what you're doing online just by knowing your IP if you have a firewall etc. But I'm no expert, so maybe I felt too save until now?

Which site did you use?

The fact they can see your NAT'ed IP - which, in fact, might just be by using your browser to show you the IP, which they might or might not in fact see at their end - doesn't mean they can do anything about it.

If Angelina Jolie called me without hiding Caller ID, I'd have her number. That doesn't mean I could see what she was doing (sadly) or hear any of her other calls. And, unlike that analogy (fantasy), I could in theory call her back. In your case, knowing your NAT'ed IP doesn't mean they could get to you through your firewall.

I'd be more concerned that they had my external IP address and could attack my router then concerned about my internal IP address. You only need to worry if your router gets compromised and starts passing ALL traffic back to your Mac. Or, if your SPI filter is incorectly config'd and is passing too much info back to your Mac.

Addresses in the private range don't get advertised beyond your router. I to think they got it via the browser.

There is always a way of finding out what goes on on a network, just imagine the recourses and money involved. I guess most of us little shrimps are in the safe.

And i would also like to know what site you used.

but there are certainly some pro's around here who can tell us more.

sounds like a dodgy site to me. :mad:

your local IP (192.xxx.xx.x) is useless to anyone unless they're on your network.

what you've got to be worried about, as has already been mentioned, is your external IP showing (ie 200.xxx.x.xxx).

i'd definitely not trust anything that site says.

Yes, it is great that your router is showing the internal ip (192.168.X.XXX) instead of your external IP. This is "your network only" so someone trying to access that IP, would most likely harm themselves. :eek:

For example, I'm 192.168.1.100. I bet that at leat 100 people on this board are also that IP.

thanks for the info and advice all. I am quite good with computers but am very new to the world of routers and networking.

I did a google for "firewall test" and that was the first result. some like to feed off normal human paranoia. pretty sleazy thing to do. I have some trust in google as they provide me with great email and my searches normally find good results so I trusted that site to be true. google let me down just this once I guess :)

They use a Java applet to get your local IP address and then transmit it back to their website. Its really no big deal. Its a sales gimick to get you to hire them or buy their products. Guess it would be like me looking up how much you paid in real estate taxes (public domain) and trying to sell you identity theft protection.

The address range 192.168.x.x (mask 255.255.255.0) is reserved for private networks and will not be routed by any normal router on the internet. So it is comlpetely useless for anyone being not pat of your LAN.

Your "external" IP address is known as soon as you do anything on the web, because NAT (Native Address Translation) does exactly that. Your Router pretends that all Computers in your LAN are just one... the router itself. As soon as you calling a server on the Web (e.g. for opening a web page) your router sends a request to the regarding server with its IP address. The IP address is the only way how the server knows to where he has to send the requested packages back. So no matter what you are doing on the web, you are leaving the IP number of your Router with every server you are using for anything on the web.

Talking about paranoia? ;)

How do you think they are tracing hackers and other cirminals on the web? By going after the IP address which can be associated with the person who (e.g.) used it for and at a certain time for his Internet Connection. A provider only has to check his log files to find out who used the IP address for a certain internet session...

I know this thread is really far back but yes i just checked that site Audit, and it detected my internal ip and when they told me to look at that patch management thing they said i had a missing patch, which i know i didnt, i have found that when you click the link they install a worm onto your browser that luckily my antivirus found and deleted

i dont know why they did that but i feel that this site is spying on us or just giving viruses

Always a good idea to disable Java support in Safari and Firefox. Your IP address can leak out to malicious websites even if you are behind a proxy.

Yep, thats an internal IP address. My internal IP is 192.168.1.100, and my other 2 machines are 192.168.1.101, and 192.168.1.102. Dont sweat that.

Lauch ping of death to 192.168.1.100 ...

Ooops, my printer just died. :eek:

Not much people can do with that info, unless you are wireless and left things on your network quite open.

If a web-site has blocked my static IP on their server, can I hide it to access the site anyway?
What have you been up to? ;)

If you have a dynamic IP reconnecting your broadband would normally do the trick. for a static IP you will have to search for a server that lets you connect through it, while holding back your IP, and showing it's own for servers you visit.
I don't know where to find these servers (like a public proxy or something)

Every server needs your IP to able to send info back to you, like letting you download (see) a website you're banned from.

And the person who wants to hack you knows where you live...which may or may not be a more pressing issue!

If they were attached to your local network perhaps they could, but that would require that they be behind your router (i.e. assigned a 192.x.x.x address) to the best of my knowledge.

I wouldn't take any 'advice' from web sites claiming you have security problems unless it's proven to be a reliable source.
