Quad9 dns

This looks interesting use this dns Quad9 DNS: Internet Security and Privacy in a Few Easy Steps and it blocks bad websites YouTube

Looks interesting, but being the type of person I am I like to check website IPs against Shodan and they have a whole pile of CVEs they need to fix. https://www.shodan.io/host/216.21.3.77

So should I trust their infrastructure and what they offer? Looks promising, but for the time being I think I'll stick to OpenDNS which has a feature to resolve a domain even if it's down. Quad9 might be great for smartphones though.

Edit-

They didn't even set the right headers either. Mozilla Observatory

I just tried hitting some malware domains and Quad9 does block them. But their ping time isn't as good as OpenDNS'.

Ping time isn't is not the best way to figure out what network is better, especially if your only interested in a single port like 53.



This program would probably give you more accurate results.

Finding the closest DNS server to your location is the best way to pick a server, Usually that would mean your ISP but many people do not trust their ISP which is justified in some cases, For me I have found Cloudflare the fastest which is about 100km from where I live. There is also a quad9 about the same distance from me.


A Google search should tell you what servers are near you:
