NextDNS-Config

Guidelines :bookmark:

1. Prevent overblocking by utilizing the law of diminishing returns (e.g., using sane, quality blocklists; allowing most TLDs; etc.).
2. Pass the grandma test with few exceptions. These deviations are documented throughout the guide.

[!WARNING] Blocking NRDs may cause false positives occasionally. Be selective when adding NRDs to your allowlist; and, if you do, NEVER give sensitive information to a NRD. If you plan to set-and-forget your configuration, disable this setting.

Privacy :lock:

Privacy features limit the amount of data companies can collect about you.

Because privacy is a spectrum, what you need varies on your threat model, interest, and skillset.^why should I care? I have nothing to hide

Blocklists 1

Blocklists filter out ads, trackers, and malicious sites. Hundreds of volunteers contribute to these lists in the open-source community, and they are the undercover heroes who make blocking ads at scale possible.

We recommend you remove the NextDNS Ads & Trackers Blocklist and add the minimum number of useful lists.

Which blocklist should I use?

A great question to ask is: "How much do I want to deal with the inconveniences of false positives?"

Here are the suggested blocklists, based on past issues and observations:

Blocklists	Rationale
HaGeZi - Multi NORMAL1 + OISD2	Block tracker, ad, and badware requests without issues (set-and-forget).
HaGeZi - Multi PRO3	Block more requests, usually without issues (recommended).
HaGeZi - Multi PRO++4	Block more requests at the risk of site breakage. Report occasional site and app issues.

[!TIP] Use different blocklists on separate DNS profiles (e.g., NORMAL for your router and PRO++ for your web browser).

You can also check out Hagezi's own recommendations.

Why Hagezi?

Hagezi block ads, trackers, native device trackers, and badware. He maintains a sensible allowlist, handles false positives quickly, and communicates known issues to blocklists maintainers. Hagezi builds his blocklists using many of the same original sources that feed into other popular lists like OISD and 1Hosts. He also adds his own unique sources, rather than just repackaging other combined blocklists.

You may also wonder why other lists are not utilized. This is because many list maintainers:

• do not remove false positives and/or are no longer active 1 2
• already aggregate common blocklists into their own list (Easylist/Fanboy, AdGuard, Steven Black, etc.) 1 2 3 4
• offer no meaningful additional coverage when compared with the chart combinations above

Native Tracking Protection 1

[!CAUTION] Leave this feature enabled if you use something other than the recommended blocklists (see https://github.com/yokoffing/NextDNS-Config/issues/76).

If you decide to use this feature, then add all the device brands that you use.

iCloud Private Relay can override DNS settings on devices, preventing NextDNS from protecting them.

Some DoH providers block this feature automatically.

[!CAUTION] The domains below may prevent external images from loading in Apple mail clients. You don't need these unless you're running a very aggressive profile.

:warning: However, because many sites use these domains for ads, allowing them could result in more ads being shown on other sites you visit.

FAQ :question:

How do I signup for NextDNS?

Click here to get started.

Why am I still seeing ads?

Not all ads can be blocked at the DNS level.1 2 You will need an ad blocker to block what's leftover.

This is because not all ads come from third-party domains; some ads come directly from the site you're visiting, like YouTube. DNS blockers stop the resolution of a domain, and content blockers filter page content. Click here to easily install a lightweight ad blocker.

I need a browser with ad blocking. Which one should I choose?

Choosing a browser is about as intimate as choosing a starter Pokémon, so here's a few caveats:

• The best browser on paper may not work well in real world usage.
• Browsers are tools! Use a variety of browsers depending on what you need to do.
• You should use various browsers (or browser profiles) for different areas of life (e.g., work, school, personal).

We based the recommendations below on a combination of effectiveness, resource efficiency, features, and ease of use.

OS	Browser	Content Blocker
iOS	Safari	wBlock, uBlock Origin Lite, or AdGuard
Android	Brave	Built-in blocker
Windows macOS Linux	Firefox (with Betterfox) Brave Helium	uBlock Origin Built-in blocker or uBlock Origin

At the end of the day, if you're using NextDNS + any browser with an ad blocker, you have more coverage than most people.

Should I pay for NextDNS?

For the rich features it provides, NextDNS is very affordable at $19.90/year for unlimited devices. NextDNS pays for itself if it saves my family from a malicious incident.

Does the amount of features enabled affect the speed of NextDNS?1 2

The number of settings you toggle on will not affect your DNS latency.

Do I need to set DoH at browser-level if I already use NextDNS at system-level?

Unless you use a separate profile for the browser, it is not neccessary. However, I recommend setting it in your web browser anyway.

I have a router profile and a device profile. Which one does my device use?

The device will use the profile set by the NextDNS app or the installed root CA. However, if the device has not been configured to use a separate profile, then it will use the wifi/router configuration.1

What is the difference between security, privacy, and anonymity?

See article | video

Does NextDNS hide activity from my Internet Service Provider (ISP)?

Encrypted DNS queries boost privacy and security. This encryption stops your ISP from seeing what websites you search for and visit.

However, encrypted DNS does not hide website IP addresses from your ISP. While your ISP cannot see the specific domain you want to access, they can see that you contact DNS servers like Cloudflare or AWS. If you repeatedly send data to a certain IP address, your ISP can guess you are visiting a website at that address.

Do I need a VPN?

IVPN argues you only need a VPN for three reasons. Mainly, in order to:

1. Hide your real IP address from websites and peer-to-peer networks, which prevents ISPs and mobile carriers from tracking your online activity.

2. Guard against man in the middle and other common attacks on public Wi-Fi networks in places like airports, hotels, cafes, and libraries.

3. Bypass censorship or geographic restrictions, allowing you to access blocked websites and content.

Ultimately, you don't need a VPN unless your threat model demands it. Here are VPN suggestions from Techlore and Tom Spark Reviews if it does.
