Using MizpahGuard with eero

eero lets you set the DNS server for your whole network in its app, which protects every device on your Wi-Fi in one step.

First: turn off eero’s own filtering

Some internet providers hand out an eero with eero’s security subscription already switched on at no extra charge. altafiber, for example, says every eero it provides comes with eero Secure included. While eero’s filters are on, eero handles DNS itself, and an eero staff reply says that turning it on changes your DNS to the one it needs “to operate”. That means your devices can keep using eero’s DNS and never ask MizpahGuard, even if the app lets you save a custom address.

  1. Open the eero app and find eero’s security section (called eero Secure or eero Plus, depending on your version).
  2. Turn off each filter that is on: Advanced Security, Ad Blocking and any Content Filters.
  3. Then do the steps below. MizpahGuard blocks at the DNS level too, so you aren’t left unprotected, but the two can’t be combined.
Not yet confirmed: We couldn’t open eero’s own help page to check the exact menu names, so they may differ in your app version. If you don’t see an eero Secure or eero Plus section at all, you can skip this step.

Set the DNS server in the eero app

  1. Open the eero app and tap Settings (bottom right).
  2. Tap Advanced networking, then DNS.
  3. Turn on Custom DNS.
  4. Enter this as the IPv4 address:74.208.171.84
  5. If the app also shows an IPv6 field, enter:2607:f1c0:f0da:1300::1
  6. Tap Save (top right).

Use only MizpahGuard’s addresses. If you leave another DNS server in the list (such as 8.8.8.8 or your provider’s), some devices will use it and skip the filter. If your internet provider gives you IPv6, fill in the IPv6 field too when the app shows one: users report eero can still hand your provider’s IPv6 DNS to devices otherwise.

If DNS is greyed out: eero’s security filtering (eero Plus or eero Secure) works by handling DNS itself, so it blocks a custom DNS setting. Turn off each filter that is enabled (see the first section) before changing DNS here. Menu names may differ slightly between app versions.

Make your devices pick it up

Devices remember the DNS they were given when they joined. After saving, turn Wi-Fi off and on for each device (or restart it) so it asks the eero again. Restarting the eero itself also works.

If it worked and then stopped

Not yet confirmed: Some eero owners report that a custom DNS setting can quietly stop being used after an eero software update, sometimes for days, even though the app still shows the address you entered. If the example.com test below stops working later, the fix people report is: set DNS back to the automatic option, save, enter MizpahGuard’s addresses again, save, and restart the eero. This comes from user reports, not from eero.

Re-check your home’s address

Go back to setup in MizpahGuard and make sure your home’s address is the one your internet connection shows. If your provider changes it, the filter stops matching until it is re-confirmed.

Devices that skip the router’s DNS

Not yet confirmed: Some smart TVs, streaming boxes and game consoles have a DNS server built in and ignore the one the router hands out, and phones or browsers using Private DNS or Secure DNS send their lookups elsewhere. We haven’t tested every device, so check each one: if it doesn’t show in your home’s Activity tab, look for a DNS setting in its own network menu and set it to automatic, or follow its guide — game consoles, iPhone / iPad / Mac, Android.

How to tell it’s working

The quick test: on the device you just set up, open example.com. On an unprotected device you see a plain page titled “Example Domain”. On a device protected by MizpahGuard you see our “It’s working” page instead — it is blocked on purpose, for every household, so you can tell at a glance. (Your browser may show a certificate warning first, as it does for any blocked site; continue past it.)

You can also open your home’s Activity tab in MizpahGuard and look for the device’s browsing within a minute. If the test page doesn’t appear, the device is still using another DNS server — recheck the steps, or contact support from your dashboard and tell us your device and internet provider.
