is dnscrypt-proxy using its own local DNS cache or the one integrated in Windows?

[Carl1971]

I had visited https://ipleak.net/ and I am not leaking any DNS resolver (I am using a resolver with DNSSEC+no logs and 127.0.0.1 as my primary DNS address). It just a curiosity since I was looking for some info about the dnscrypt-proxy and the DNS local cache it uses (without having a third local DNS caching service like dnsmasq installed) and I didn't find anything concrete.

I am asking you this because I am using Simple DNSCrypt with the option Cache enabled (I suppose that GUI it's setting up the cache=true parameter from behind) I see how all the DNS queries are been registered in the ipconfig /displaydns command. I clean and disable it and I still see all my DNS queries been locally cached by Windows, so:

• Is Windows always caching all my DNS queries whether I am using DNSCrypt or any other DNS local cacher program?. It represents any threat to my privacy or it leaks my queries to outside? should I disable the Windows cache then?
• I am thinking in using a third party service like unbound or dnsmasq to create a local cache because as I read it can add some privacy and speed to my resolutions. Do you recommend me this?

Thank you all for your help and work with this amazing project! :D

Hi!

It has its own DNS cache. So, adding something like dnsmasq is not required.

Hi!,

First of all, apologize for my delay I was in a travel until yesterday (BTW, that was a fast reply :D). Good to know about the fact that it uses its own cache but, in the future, I will create an Unbound setup for other features. So Windows is registering all the DNS requests in its local cache anyway, then I had another question in this regard:

Could the local DNS cache of Windows and the one built-in Firefox/Chrome leak some DNS information?

BTW, I read some months ago about You leaving the project and now using a VPN (I think it was a tweet actually) I am really happy about you continuing the Dnscrypt-proxy with this new version. I've been using your software for some years (even without Simple DNSCrypt) and I learnt a lot about the DNS protocol since the very first day I discover your project and start researching about it, so thank you so much for all those years of work.
