What is 149.112.112.112?
149.112.112.112 is the secondary DNS resolver address for Quad9,
operated by Quad9 Foundation — the backup your device falls back to when the primary

How 149.112.112.112 works as a secondary address
149.112.112.112 is a backup resolver. Your operating system sends each DNS query to
your primary DNS server first — for Quad9 that's 9.9.9.9 and
only turns to 149.112.112.112 if the primary doesn't answer in time. It isn't queried in parallel, and
it isn't "faster" or "slower" than the primary — it points to the same Quad9 service. The reason
to set it is resilience: if the primary has a brief hiccup, your device keeps resolving
names instead of failing.
Set 9.9.9.9 as your primary DNS and 149.112.112.112 as the secondary to get Quad9 either way.
Time 149.112.112.112 from your connection
This runs a live timing check against Quad9's encrypted DoH endpoint — a
browser can't query the raw IP 149.112.112.112 directly, so this is the closest honest measurement of
that resolver from your network. Nothing is fabricated: if the endpoint can't be reached or read, the tool
says so instead of guessing a number.
Runs in your browser against the resolver's DoH endpoint; nothing is stored. For a full multi-resolver comparison on your connection, use the DNS speed test.
Should you use it?
A security-first non-profit resolver that blocks known malicious domains and keeps no source-IP logs.
Best for: Security, Malware blocking, Privacy.
Like any public resolver, Quad9 adds a small round trip compared with your ISP's default DNS, and it can't optimize CDN routing as tightly as a resolver peered locally with your network in every case. Use the live timing check above, or the full DNS speed test, to see whether it's actually faster than what you have now.
To use Quad9, set 9.9.9.9 as your primary DNS
and 149.112.112.112 as the secondary
— see the device and router setup guides

What's the difference between 149.112.112.112 and 9.9.9.9?
9.9.9.9 is Quad9's primary DNS address and 149.112.112.112 is the secondary. Your device queries the primary first and only falls back to 149.112.112.112 if the primary stops answering. Both point to the same Quad9 service with the same features, so the secondary is there for redundancy, not extra speed — set 9.9.9.9 as your first DNS entry and 149.112.112.112 as the second.
