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

Unlike the version embedded in some browsers, this feature does not associate your public IP address to threats and does not allow bypassing the block.

Block Newly Registered Domains (NRDs) 1
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.

Important
Blocking TLDs risks blocking legitimate sites along with malicious ones, since this feature stops both site navigations and subrequests. However, the entries below should allow for everyday browsing while offering protection against commonly abused TLDs.

.autos
.best
.bid
.boats
.boston
.boutique
.charity
.christmas
.dance
.fishing
.hair
.haus
.loan

You can find additional entries on Most Abused TLDs, but you may need to allowlist sites on occasion. If you plan to set-and-forget your configuration, skip this step.

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.
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 OISD |
Block tracker, ad, and badware requests without issues (set-and-forget). |
| HaGeZi - Multi PRO2 OISD |
Block more requests, usually without issues (recommended). |
| HaGeZi - Multi PRO++3 OISD |
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).
Note
NextDNS does not offer Hagezi's Threat Intelligence Feed (TIF). We suggest using the OISD list, which contains some TIF sources missing from NextDNS security features.
You can also check out Hagezi's own recommendations.
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's primary DNS lists combine multiple sources including respected community blocklists like OISD, Steven Black, 1Hosts, notrack, and more.
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

Block Bypass Methods 1
Block tools that can bypass NextDNS filtering, such as VPNs, proxies, Tor software, and encrypted DNS services.
Caution
Enabling this setting causes unintended behavior.
Block Bypass Methods
Denylist entries are always blocked. These entries may further harden some profiles while not interfering with everyday browsing.
iCloud Private Relay can override DNS settings on devices, preventing NextDNS from protecting them.
Some DoH providers block this feature automatically.
mask.icloud.com
mask-h2.icloud.com
mask-canary.icloud.com
And possibly:
apple-relay.cloudflare.com
apple-relay.fastly-edge.com
doh.dns.apple.com
doh.dns.apple.com.v.aaplimg.com
mask-api.icloud.com
mask.apple-dns.net
Allowlist entries always resolve. These entries may be needed for aggressive DNS profiles to relax their rules.
Allow NextDNS itself in case a filterlist goes haywire and blocks your access.

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.
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 | AdGuard |
| Android | Brave | Built-in blocker |
| Windows macOS Linux |
Firefox (with Betterfox) | 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.
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.
The number of settings you toggle on will not affect your DNS latency.
Unless you use a separate profile for the browser, it is not neccessary. However, I recommend setting it in your web browser anyway.
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
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.
IVPN argues you only need a VPN for three reasons. Mainly, in order to:
-
Hide your real IP address from websites and peer-to-peer networks, which prevents ISPs and mobile carriers from tracking your online activity.
-
Guard against man in the middle and other common attacks on public Wi-Fi networks in places like airports, hotels, cafes, and libraries.
-
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.
