I have been in conversations the place folks assume privateness begins with apps, browsers, or VPNs, and I’m wondering why DNS will not be thrown into these conversations.
It is a system that always runs within the background to translate internet addresses into IP addresses, and altering it’s my first suggestion relating to privateness. By altering it, particularly to a privacy-focused possibility like Quad9, you modify a significant default conduct, altering what the community can expose even earlier than different elements load.

It’s best to keep away from browser VPNs for safety and efficiency causes.

Why each web site you open begins with a request you do not see

Whenever you open an internet site, one of many first issues your system does is question a DNS server to find out the positioning’s IP handle. This seemingly routine activity has one of the vital constant metadata trails. However it’s totally different from most different types of monitoring as a result of it occurs even earlier than a web page hundreds.
Intent is a component folks do not all the time trouble to guard. Regardless that you depend on HTTPS for content material safety, ISPs and default DNS suppliers might be able to construct an image of your searches, web site visits, and what you learn. This nonetheless holds even when the web page is encrypted. This is not pointing to an unique surveillance scheme, however simply the default construction of the web.
Visibility usually sits on these three layers:
Layer
What’s uncovered
HTTPS
Web page content material is encrypted and hidden from third events
DNS question
The area title (e.g., mentalhealth.org) is seen to your DNS resolver
IP connection
The vacation spot server handle stays seen to your ISP
Whereas DNS does not expose every part, it may persistently level to the vacation spot even when it isn’t seeing precise content material. This turns into extra vital on public Wi-Fi, the place DNS requests is probably not encrypted and are handed via public default resolvers. This offers the community supplier visibility into area lookups you make in actual time. Quad9 helps mitigate this default conduct.

The principle concept of Quad9 is to cease your DNS visitors from getting used for profiling or business achieve. It is totally different from Google and Cloudflare within the sense that it isn’t affiliated with any promoting enterprise or adjoining companies that will profit from realizing your shopping habits.
Quad9’s privateness coverage can be extra tangible than a lot of the competitors. Quad9 doesn’t log IP addresses for DNS queries. Architecturally, this info is dropped on the community edge. Nonetheless, it retains city-level combination geographic info for community capability planning. Quad9 DNS is stripped of any mechanism that may retailer or accumulate personally identifiable DNS knowledge.
Functionally, it operates otherwise from commonplace resolvers. It ensures any reference to flagged domains is rarely accomplished. That is potential attributable to its safety companions and blocked domains that host malware, phishing pages, or botnet infrastructure. This is a vital safety level as a result of many phishing assaults succeed after an unintentional click on.
However it runs deeper. In 2021, when Sony Music tried to make use of a Hamburg court docket injunction to compel Quad9 to dam domains globally, Quad9 fought again and gained the case. The truth that a DNS firm was prepared to go to court docket and defend its operational neutrality is a big credibility sign. The core of Quad9 is to vary the defaults of what web connections enable via.
Switching to Quad9 takes minutes and covers your complete community
Router-level setup is the one step most individuals really need
The first addresses are:
- 9.9.9.9 – safe, malware-blocking (beneficial default)
- 149.112.112.112 – secondary
For finest outcomes, arrange Quad9 in your router. This ensures gadgets linked to that community mechanically use Quad9 with no need particular person tweaks. Nonetheless, you’ll have to fall again to a device-level setup if it’s good to use gadgets exterior your own home community. This could possibly be Home windows’ guide DNS, macOS’ community settings, Android’s Personal DNS mode, or iOS’ per-network Wi-Fi DNS settings.
With Quad9, chances are you’ll select between three distinct service choices:
Deal with
What it does
When to make use of it
9.9.9.9
Safe DNS with malware and phishing blocking
Default alternative for many customers
9.9.9.10
Unfiltered DNS, no blocking of any sort
Use for debugging or whenever you need pure DNS decision
9.9.9.11
Safe DNS with ECS enabled for CDN optimization
In the event you discover slower loading on main streaming or CDN-heavy websites
Some routers require HTTP/2 to make use of DNS-over-HTTPS with Quad9; in case your router solely helps HTTP/1.1 the connection could fail with out error messages. If this occurs, switching to DNS-over-TLS will repair it. Verify the repair by working a leak take a look at and checking for Quad9 IP addresses.
Quad9 in comparison with mainstream DNS suppliers
Google Public DNS and Cloudflare 1.1.1.1 are the extra frequent options to Quad9. These are core variations I seen when utilizing them:
Quad9
Cloudflare 1.1.1.1
Google 8.8.8.8
Group kind
Nonprofit basis
Industrial CDN firm
Industrial promoting firm
Malware blocking
Sure, on by default
Non-compulsory — requires switching to 1.1.1.2
No
IP handle logging
By no means saved
Deleted inside 24 hours, KPMG-audited
Anonymized after two weeks
Authorized jurisdiction
Switzerland
United States
United States
Main function
Safety and privateness
Velocity and reliability
Ecosystem efficiency
There are structural variations between these choices. Cloudflare can be a great privateness possibility and a favourite for anybody who prioritizes uncooked pace. Nonetheless, the place of Quad9 is narrower. It resolves DNS, blocks recognized threats, and has no business incentive to monetize DNS knowledge.
Regardless that it does not anonymize shopping or encrypt your full visitors, it may considerably scale back phishing and malware publicity.
