DNS leaks?

Postby justsomeguy » Sun Jul 02, 2017 9:22 pm

Hey guys, I used the website

DNS Leak Test

to test a possible DNS leak and it looks like that it is the case for me.

I use the cryptostorm Windows Client and have activated the options "Disable IPv6" and "DNS leak prevention", so normally I should be save from leaks, no?

Here is an example (using the german cryptostorm connection and openDNS as DNS service):

What is even weirder is that when I use my local DNS service only my ISP shows up and nothing about CS DNS service.

Do you know what could be the reason and how I can prevent this?

@OP

Are you saying that you DO NOT expect to see OpenDNS addresses in that listing?

I'm not really sure what is supposed to be shown or not with the opendns stuff, what I'm more worried about is that when I use the DNS service of my ISP, the dns leak site shows that all my DNS requests are handled by my ISP while I'm connected to cryptostorm.

Let me make a screenshot to make it more clear what I'm worried about.

Now using the DNS from my ISP:

As you can see, even though I am connected to the cs-net all my DNS requests are still handled by my provider, shouldn't your config prevent exactly this? I will probably keep using the openDNS from now on, but I was still a bit shocked when I saw how easily that website could find my real place, especially because the ISP DNS is standard until you change it.

(sorry for the double post, but I couldn't edit the post since it was still waiting for approval)

@OP

Can we assume that you set the OpenDNS servers manually in the Windows network settings? If so, it would appear that the CS widget isn't updating your DNS settings dynamically, which means that (if you don't specify the OpenDNS servers) your PC continues to use what is handed to it by the DHCP server running on your router. That would be my guess.

1) Which version of Windows are you using?
2) Which version of the widget are you using?

I set the OpenDNS servers manually in my router settings (Netgear Genie).

I'm using Windows 10 Pro and the newest widget version (2.22).

I use https://simplednscrypt.org/ on Winblows 10 ... fwiw hope it helps

also i read that ipv6 is not entirely disabled as some of the more permanent changes are only possible via the registry etc.

ymmv so some messing about with the internals of the winblows os.
