How DNS works on an Eero network
Changing DNS on Eero can improve browsing speed, filtering, and privacy, but only if you understand how Eero handles network-wide settings.
This guide explains how to change DNS safely on your Eero network without breaking client connectivity, parental controls, or device resolution.
DNS, or Domain Name System, translates human-readable domains like example.com into IP addresses.
On Eero, DNS settings are applied at the router level, so the configuration affects every device that uses the mesh network.
Why people change DNS on Eero
Home users and small businesses often change DNS to get more reliable name resolution or better control over internet requests.
Common reasons include faster lookup times, enhanced privacy, safer browsing, and access to content filtering features from trusted DNS providers.
- Performance: Some DNS resolvers answer queries faster than the default ISP DNS.
- Privacy: Reputable third-party resolvers may collect less browsing metadata.
- Security: Filtering services can block known malicious domains.
- Parental controls: DNS-level filtering can help restrict adult or unwanted content.
Before you change DNS on Eero
Before making changes, check whether your current Eero setup uses any features that depend on the existing network configuration.
If you use Eero Secure, ad blocking, content filters, or custom device controls, review how a new DNS provider may interact with those features.
It is also wise to identify the DNS provider you plan to use and confirm that it supports your goals.
Popular options include Google Public DNS, Cloudflare, OpenDNS, Quad9, and NextDNS, each with different privacy and filtering policies.
Key checks before editing DNS
- Confirm you have admin access to the Eero app.
- Write down the current DNS settings so you can revert quickly.
- Choose a trusted provider with published IP addresses.
- Make sure the provider supports IPv4 and, if needed, IPv6.
- Test whether the provider offers filtering or logs that match your needs.
How to change DNS safely on your Eero network
The safest approach is to change DNS in small steps, verify each change, and keep a rollback plan ready.
Eero typically allows DNS changes through the mobile app, where you can set custom DNS servers for the entire network.
Step 1: Open the Eero app
Launch the Eero app on your smartphone or tablet and sign in using the account that manages the network.
From the home screen, select the network you want to modify if you manage multiple locations.
Step 2: Find network settings
Go to Settings, then look for Network settings or a similar menu depending on your app version.
DNS settings are usually grouped with advanced network options.
Step 3: Choose custom DNS
Select the option to use custom DNS instead of automatic DNS.
Enter the primary and secondary DNS server addresses provided by your chosen resolver.
Using two resolvers improves resilience if one server becomes unavailable.
Step 4: Save and wait for the network to update
After saving, allow the Eero system a few minutes to push the new settings across the mesh.
Devices may briefly reconnect while the change takes effect.
Step 5: Test resolution on multiple devices
Open several websites on phones, laptops, and smart devices connected to the Eero network.
If pages load normally and names resolve correctly, the new DNS settings are likely working as expected.
Recommended safe DNS practices
To reduce the risk of outages or broken apps, use DNS changes that are simple, reversible, and well documented.
Small home networks benefit from conservative changes more than aggressive experimentation.
- Use a trusted provider: Pick a resolver with a clear privacy policy and strong uptime record.
- Avoid mixing many providers: Keep primary and secondary DNS within the same service when possible.
- Keep automatic settings documented: Save the original DNS values before editing.
- Change one variable at a time: Do not alter DNS, parental controls, and firewall settings simultaneously.
- Monitor for DNS leaks: Verify that devices are using the intended resolver.
DNS providers commonly used with Eero
The best DNS provider depends on whether you want speed, security, or filtering.
Here is a practical overview of common options used on Eero networks.
Cloudflare DNS
Cloudflare Public DNS is known for fast response times and a privacy-focused posture.
Its standard resolver is a common choice for users who want quick lookups without content filtering.
Google Public DNS
Google Public DNS is widely available and stable.
It is often used as a straightforward replacement for ISP DNS, especially when compatibility is a priority.
OpenDNS
OpenDNS offers optional filtering and parental control features.
It may be useful for households that want DNS-level content blocking.
Quad9
Quad9 focuses on security by blocking lookups to known malicious domains.
It is a strong option for users prioritizing threat reduction over customization.
NextDNS
NextDNS provides detailed filtering, analytics, and per-device policies.
It is popular with advanced users who want granular control over DNS behavior.
Common mistakes to avoid
Most DNS problems on Eero come from misconfiguration rather than the DNS provider itself.
Avoiding a few common mistakes can save time and prevent unnecessary downtime.
- Using invalid IP addresses: DNS fields must contain resolver IPs, not domain names.
- Forgetting IPv6: If your network uses IPv6, make sure the DNS plan covers it too.
- Overlapping filters: Multiple filtering layers can cause blocked sites or false positives.
- Not testing smart devices: Streaming boxes, printers, and IoT devices may behave differently from phones.
- Changing settings during peak use: Update DNS when the network is least busy so issues are easier to spot.
How to verify your Eero DNS change
Verification helps confirm that the Eero system is actually using the new resolver.
A successful browser test is useful, but it is not enough on its own.
You can check resolver behavior by visiting a DNS leak test site, reviewing your device network details, or using command-line tools such as nslookup or dig.
If the results show the intended DNS provider, your configuration is correct.
What to look for during testing
- Websites load without delay or certificate warnings.
- Apps that depend on DNS, such as streaming and messaging, remain functional.
- Resolver results match the provider you configured.
- No device is falling back to an ISP DNS server unexpectedly.
How to roll back DNS changes quickly
If something breaks after the update, revert to the original DNS settings right away.
In the Eero app, switch the network back to automatic DNS or re-enter the previous resolver values you saved earlier.
A quick rollback is especially important if you notice widespread failures, captive portal issues on guest Wi-Fi, or problems with work VPN access.
Restoring the prior setup should be the first troubleshooting step before making more changes.
When not to change DNS on Eero
Sometimes the safest choice is to leave DNS alone.
If your ISP DNS is stable, your network uses specialized parental controls, or you rely on Eero-managed filtering that may conflict with third-party resolvers, a change may create more problems than benefits.
For complex households, it may be better to use DNS filtering selectively on individual devices rather than changing the entire network.
That approach can preserve compatibility while still improving privacy or security where needed.
