# Guidelines :bookmark:
1) Prevent overblocking by utilizing the [law of diminishing returns](https://pmctraining.com/site/wp-content/uploads/2018/04/Law-of-Diminishing-Returns-CHART.png) (e.g., using [sane](https://privacyguides.org/basics/threat-modeling), quality [blocklists](https://github.com/yokoffing/NextDNS-Config#blocklists-1); allowing most [TLDs](https://github.com/yokoffing/NextDNS-Config#block-top-level-domains-tlds-1-2-3-4-5-); etc.).
2) Pass the [girlfriend test](https://urbandictionary.com/define.php?term=Grandma%20Test) with few exceptions. These deviations are documented throughout the guide.

# Privacy :lock:
Privacy features limit the amount of data companies can collect about you.
Because privacy is a [spectrum](https://blog.thenewoil.org/the-privacy-myth-binary-vs-spectrum), what you need varies on your [threat model](https://thenewoil.org/en/guides/prologue/threatmodel), interest, and skillset.<sup>^[*why should I care? I have nothing to hide*](https://medium.com/@FabioAEsteves/i-have-nothing-to-hide-why-should-i-care-about-my-privacy-f488281b8f1d)</sup>
## Blocklists <sup><sup>[1](https://github.com/nextdns/blocklists/tree/main/blocklists)</sup></sup>
Blocklists filter out ads, [trackers](https://freecodecamp.org/news/what-you-should-know-about-web-tracking-and-how-it-affects-your-online-privacy-42935355525/), and malicious sites. Hundreds of volunteers contribute to these lists in the [open-source](https://opensource.com/resources/what-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](https://github.com/nextdns/blocklists/blob/main/blocklists/nextdns-recommended.json) and select the [minimum](https://www.reddit.com/r/nextdns/comments/1048xeg/do_you_use_nextdns_blocklist_as_the_primary/j33wnz2/?context=3) 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](https://csrc.nist.gov/glossary/term/false_positive)?"
Here are the suggested blocklists, based on past [issues](https://github.com/hagezi/dns-blocklists/issues?q=author%3Ayokoffing) and [observations](https://github.com/hagezi/dns-blocklists/discussions/1093):
| **Blocklist** | **Rationale** |
|:--------------------:|:--------------------------------------------------------------------------------------:|
| HaGeZi - Multi **NORMAL**<sup>[1](https://github.com/hagezi/dns-blocklists/blob/main/statistics.md#multi)</sup> | Block tracker and ad requests without issues ([set-and-forget](https://glosbe.com/en/en/set-and-forget)). |
| HaGeZi - Multi **PRO++**<sup>[2](https://github.com/hagezi/dns-blocklists/blob/main/statistics.md#proplus)</sup> | Block signficantly more requests at the risk of site breakage. <br> [Report](https://github.com/hagezi/dns-blocklists/issues/new/choose) occasional site and app issues. |
:book: Check out Hagezi's own [recommendations](https://github.com/hagezi/dns-blocklists/tree/main#whatshouldiuse).
:bulb: You can use different blocklists on separate DNS profiles (e.g., NORMAL for your router and PRO++ for your web browser).
### Why Hagezi?
[Hagezi](https://github.com/hagezi/dns-blocklists) block ads, trackers, native device trackers, badware, and more. He maintains a sensible allowlist, handles false positives quickly, and communicates known issues to blocklists maintainers. Hagezi's primary DNS lists combine respected community blocklists like [OISD](https://oisd.nl/), [Steven Black](https://raw.githubusercontent.com/StevenBlack/hosts/master/hosts), [1Hosts](https://github.com/badmojr/1Hosts#safeguard-your-devices-against-pesky-ads-trackers-and-malware), [notrack](https://gitlab.com/quidsup/notrack#notrack), and [more](https://github.com/hagezi/dns-blocklists/blob/main/sources.md).
:question: You may wonder why other lists are not utilized. This is because many list maintainers:
* do not remove [false positives](https://csrc.nist.gov/glossary/term/false_positive) and/or are no longer active <sup>[1](https://github.com/lightswitch05/hosts/issues/356) [2](https://github.com/EnergizedProtection/block/issues/916)</sup>
* already [aggregate](https://www.reddit.com/r/nextdns/comments/ys3s1s/confused_about_blocklists/ivxdcd2/?context=3) common blocklists into their own list (Easylist/Fanboy, AdGuard, Steven Black, etc.) <sup>[1](https://github.com/badmojr/1Hosts/blob/master/-data/lists/assets.txt) [2](https://oisd.nl/includedlists/big/0) [3](https://github.com/jerryn70/GoodbyeAds/blob/master/Docs/Sources.md) [4](https://github.com/hagezi/dns-blocklists/blob/main/usedsources.md#proplus) </sup>
* offer no meaningful additional coverage when compared with the chart combinations above

# FAQ :question:
## How do I signup for NextDNS?
Click [here](https://nextdns.io/?from=xujj63g5)!
## Why am I still seeing ads?
Not all ads can be blocked at the DNS level.<sup>[1](https://www.reddit.com/r/nextdns/comments/14nsfhv/comment/jq982bi/?context=3) [2](https://www.reddit.com/r/nextdns/comments/13urdda/ads_on_manga_sites/)</sup> You will need an [ad blocker](https://github.com/yokoffing/NextDNS-Config#i-need-a-browser-with-ad-blocking-which-one-should-i-choose) 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](https://discourse.pi-hole.net/t/how-do-i-block-ads-on-youtube/253/2). DNS blockers [stop](https://github.com/hagezi/dns-blocklists/discussions/1030#discussioncomment-5884270) the resolution of a domain, and content blockers filter page content. Click [here](https://github.com/yokoffing/NextDNS-Config/tree/main#i-need-a-browser-with-ad-blocking-which-one-should-i-choose) 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](https://youtu.be/F_8htiBjTCY), so here's a few caveats:
* The best browser on paper may not work well in real world usage (e.g., [Brave](https://brave.com/) is wonky with video playback on iOS).
* 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](https://www.apple.com/safari) | [AdGuard](https://adguard.com/en/adguard-ios/overview.html) or [Ghostery](https://www.ghostery.com/ghostery-ad-blocker) |
| Android | [Firefox](https://www.mozilla.org/en-US/firefox/new/) | [uBlock Origin](https://addons.mozilla.org/blog/ublock-origin-everything-you-need-to-know-about-the-ad-blocker/) or [Ghostery](https://www.ghostery.com/ghostery-ad-blocker) |
| Windows <br> macOS <br> Linux | [Firefox](https://www.mozilla.org/en-US/firefox/new/) (with [Betterfox](https://github.com/yokoffing/Betterfox#betterfox)) | [uBlock Origin](https://addons.mozilla.org/blog/ublock-origin-everything-you-need-to-know-about-the-ad-blocker/) or [Ghostery](https://www.ghostery.com/ghostery-ad-blocker) | |
At the end of the day, if you're using [NextDNS](https://nextdns.io/?from=xujj63g5) + 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](https://nextdns.io/?from=xujj63g5) 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?<sup>[1](https://github.com/yokoffing/NextDNS-Config/issues/12#issue-1465457977) [2](https://www.reddit.com/r/nextdns/comments/135utai/comment/jilbus8/?=&context=3)</sup>
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](https://www.reddit.com/r/nextdns/comments/yfjvqy/is_it_redundant_to_set_at_doh_at_browserlevel_if/iu3vjzt/?context=3). However, I recommend [setting it in your web browser](https://itechtics.com/dns-over-https/#how-to-enable-or-disable-dns-over-https-in-your-browsers) 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](https://nextdns.io/?from=xujj63g5) app or the installed [root CA](https://help.nextdns.io/t/g9hmv0a/how-to-install-and-trust-nextdns-root-ca). However, if the device has not been configured to use a separate profile, then it will use the wifi/router configuration.<sup>[1](https://www.reddit.com/r/nextdns/comments/yf4hnv/question_about_home_router_and_app_running_in/)</sup>
## What is the difference between security, privacy, and anonymity?
See [article](https://thenewoil.org/en/guides/prologue/secprivanon/) | [video](https://youtu.be/Wpkh-hfULgE)
## Does NextDNS hide activity from my Internet Service Provider (ISP)?
[No](https://www.reddit.com/r/nextdns/comments/tavcgm/comment/i039u1r/?context=3). [NextDNS](https://nextdns.io/?from=xujj63g5) is only concerned about DNS traffic. You would need a [quality](https://www.youtube.com/watch?v=cK4MQv-OwyM) [VPN](https://www.ivpn.net/blog/why-you-dont-need-a-vpn/) to hide all activity from your ISP.
