Can you change DNS on a Fios router?

Yes.

Verizon's Fios routers let you set your own DNS servers for IPv4. It's a few screens deep; the steps below go straight there.

Before you start

  1. Make a free DNSAFE account at my.dnsafe.net. No card needed.
  2. Register your home connection. In the app, go to Devices›Add a home connection. Your home's internet address is filled in for you. DNSAFE uses it to know the lookups are yours, so do this from home.
  3. Keep these two addresses handy. They're the same for every brand of router.
    Your DNSAFE addresses
    Primary DNS3.12.124.91
    Secondary DNS3.11.62.44

    Use both DNSAFE addresses. Don't put your internet provider's DNS in the second box: lookups that go there aren't filtered.

Change DNS on your Fios router

  1. Log in. On a device connected to your Fios router, open myfiosgateway.com (or 192.168.1.1) and sign in with the admin password on the router's sticker.
  2. Open the connection settings. Go to Advanced›Network Settings›Network Connections. Find Broadband Connection (Ethernet or Coax), click Edit, then Settings. (On older Fios routers: My Network›Network Connections.)
  3. Enter DNSAFE. Under IPv4 DNS, choose Use the following IPv4 DNS Addresses and enter your Primary and Secondary addresses from the box above.
  4. Save. Click Apply on each screen as you go back. Devices pick up the change as they reconnect.

Looking at a page called Dynamic DNS? That's a different feature. The setting you want is under the Broadband Connection.

Menu names can change with updates. If yours look different, the provider's own page is linked under Sources.

Check it worked

  1. Open blocktest.dnsafe.net on any device on your Wi-Fi. You should see the DNSAFE block page. That means filtering is on.
  2. Or run the DNS leak test. It should show DNSAFE answering your lookups.
  3. Still seeing the normal page? Turn Wi-Fi off and on again on that device (it keeps the old settings for a while), then try again.

Stop IPv6 DNS from skipping DNSAFE

Many internet providers give homes IPv6 as well as IPv4. Your router can then hand devices a second DNS server, your provider's IPv6 one, and phones and laptops may use it instead of DNSAFE. Lookups that go there aren't filtered. Do this if the protection test says Partly protected, or the block test works on some devices and not others.

  1. Log in at myfiosgateway.com.
  2. Turn IPv6 off. Go to Advanced›Network Settings and open the IPv6 settings. Turn IPv6 off and click Apply. Verizon says the router keeps working normally for everything on IPv4; the user guide for your model (under Sources) shows the exact screen.

Then turn Wi-Fi off and on on your phone and run the protection test. It should say Protected. Browsing, streaming and gaming keep working over IPv4. If you'd rather keep IPv6, protect each phone and computer with its own DNS ID instead: in the DNSAFE app, add the device. DNS IDs send every lookup to DNSAFE.

If something's not right

Websites stopped loading after the change

DNSAFE doesn't recognise your home's internet address yet. Open my.dnsafe.net from home: it will offer to use the new address. Internet providers change it from time to time; here's how to keep it up to date automatically.

Some devices aren't filtered

Your internet provider's IPv6 DNS is the usual reason: see Stop IPv6 DNS from skipping DNSAFE. A device with its own DNS setting, a browser with “secure DNS” turned on, or a VPN can also go around your router: see how to stop DNS filtering bypass, or set DNSAFE up on that device too.

Some devices still aren't filtered (IPv6)

Your provider's box may also hand out its own IPv6 DNS, which phones and computers can use instead. See Stop IPv6 DNS from skipping DNSAFE.

Frequently asked questions

Can I undo it?

Yes. In the same Broadband Connection settings, set IPv4 DNS back to getting it automatically and click Apply.

I have Verizon 5G Home Internet

The 5G Home routers are set up differently, and some don't let you change the DNS they hand out. Use your own router behind it, or protect each device with DNSAFE.

Does changing DNS slow down my internet?

Usually not. DNSAFE answers from the region nearest you. Pages load the same; blocked sites just don't open.

Do I still need antivirus?

Yes. DNS filtering stops bad sites before they load, but it doesn't scan files already on a device. Use both.
