What is my DNS server?
Which DNS resolver answers your lookups right now — your provider's, a public one like 1.1.1.1 or 8.8.8.8, or your VPN's — and whether your queries travel encrypted. One quick query against our own test zone shows the resolver's real address rather than what your settings claim.

Asking your resolver for a unique hostname…
Checking
Your DNS resolver
The page triggers a lookup for a unique hostname under our test zone and reports which resolver asked our nameserver for it, with its operator and country.
Resolver IP and operator
The address of the recursive resolver that reached our server and the network it belongs to: your ISP, a public operator (Cloudflare, Google, Quad9, OpenDNS and others are recognized by ASN), or your VPN provider. If it is your own address, you run a local resolver (Pi-hole, Unbound). Several resolvers can appear if your system uses more than one; the DNS leak test runs the longer version.
Is your DNS encrypted?
If your browser or system uses DNS over HTTPS or DNS over TLS, the resolver we see is the encrypted service's (for example Cloudflare's or Google's) rather than your network's. We show the resolver's identity; whether the last hop from your device was encrypted is determined by your settings, which we point you to below.
DNS over HTTPS / TLS
DoH wraps queries in HTTPS; DoT uses TLS on port 853. Both hide your lookups from the local network and your ISP and prevent tampering. Chrome, Edge and Firefox can enable DoH in their settings; Android has Private DNS (DoT); Windows 11 and iOS support it system-wide.
How to change your DNS server
You can set the resolver per device or once on the router for the whole network.
Windows
Settings › Network & internet › the active connection › DNS server assignment › Edit › Manual: enter the resolver's IPv4 (and IPv6) addresses; Windows 11 offers DNS over HTTPS per address. ipconfig /flushdns afterwards.
macOS
System Settings › Network › the active connection › Details › DNS: add the resolver addresses and remove the old ones. For encrypted DNS install a configuration profile from the resolver's provider.
Android (Private DNS)
Settings › Network & internet › Private DNS › Private DNS provider hostname: enter the resolver's DoT hostname (for example one.one.one.one or dns.google). This applies to Wi-Fi and mobile data.
iPhone
iOS has no manual field for encrypted DNS; install the resolver provider's configuration profile, or set plain DNS per Wi-Fi network under Settings › Wi-Fi › ⓘ › Configure DNS › Manual.
Router
In the router's WAN or DHCP settings, replace the provider's resolvers with the ones you want; every device that gets its settings by DHCP will use them after reconnecting. Devices with their own manual DNS are unaffected.
Frequently asked questions
How do I find my Wi-Fi DNS server?
Load this page: it shows the resolver that actually answered, which on Wi-Fi is whatever the router hands out unless the device overrides it. The router's DHCP or WAN page shows the configured value.
What should my DNS server be on my router?
Any resolver you trust that is fast from your location: your provider's (default), Cloudflare 1.1.1.1, Google 8.8.8.8, Quad9 9.9.9.9 (with malware filtering), or a filtering resolver for a family network. Measure with the DNS speed test.
What does changing DNS to 8.8.8.8 do?
Your lookups go to Google's public resolver instead of your provider's. Google sees the domains you look up (its privacy policy applies), your provider no longer does, and answers may be faster or slower depending on where you are.
Is 8.8.8.8 the fastest DNS?
Not necessarily. The fastest resolver is the one with the nearest server and a warm cache for the sites you use; it is often Cloudflare or your ISP's. Test from your own connection rather than trusting a general claim.
How do you reset the DNS server?
Set the DNS assignment back to Automatic (DHCP) on the device, or remove the manual entries, then flush the cache: ipconfig /flushdns on Windows, sudo dscacheutil -flushcache; sudo killall -HUP mDNSResponder on macOS. Rebooting the router resets its own cache.
What is my IP and DNS?
Your IP address is at the top of the homepage; your DNS resolver is shown at the top of this page. They are separate things: the address identifies your connection, the resolver answers your name lookups.
