THE COMPLETE TOOLKIT / 06

DNS Lookup

See what your domain is saying.

Inspect DNS records, check DNSSEC, and look up reverse DNS.

A · AAAA · MX · TXT · DNSSEC
Look up DNS ↗

WHOIS Lookup

Know who’s behind a domain.

Find registration dates, registrar details, nameservers, and network ownership.

DOMAIN · IP · ASN
Check ownership ↗

Propagation Checker

Did your DNS change arrive?

Compare answers across independent public resolvers to spot cache differences.

MULTI-RESOLVER COMPARISON
Check propagation ↗

Email DNS Checker

Check the records behind delivery.

Inspect email routing and authentication with plain-English findings.

MX · SPF · DMARC · DKIM
Check email DNS ↗

What’s My IP?

See your connection from outside.

Find your public IPv4 and IPv6 addresses, reverse DNS, and network owner.

MEASUREMENT WITH CONTEXT

A fast answer should also be a useful one.

Our benchmark ranks validated responses by median latency and shows the variation behind each result. It measures browser-to-DoH performance on your current network.See how the benchmark works ↗

Run the benchmark

Before you start — what this sends, and to whom

  • Your browser will make DNS-over-HTTPS requests directly to … third-party resolvers. Each provider you contact can see your IP address and the test name being queried, and may log it under its own privacy policy.
  • The queries use a controlled test name under dnsbenchmarkpro.com. Nothing about your browsing, device or identity is placed in a query name.
  • This tool does not request your location. No geolocation prompt, no coordinates, no reverse-geocoding service.
  • Results stay in this browser tab. Nothing is uploaded to our servers, and nothing is stored unless you export it yourself.

Provider privacy policies are linked in the resolver comparison. Our own data flow is documented in the privacy policy.

A cached lookup is what you experience most of the time. An uncached lookup is an upper bound, not a typical result.

Before you change your DNS settings

A low figure in the table above is a reason to try a resolver, not proof it will be faster for your whole system. What you measured here is an HTTPS request from this browser to a provider’s DNS-over-HTTPS endpoint. What you would configure in Windows, macOS or your router is usually that provider’s classic DNS service on port 53 — a different endpoint, transport and cache. Related, frequently correlated, but not the same measurement.

Write down what you have now

Before changing anything, record your current settings so you can put them back. On most systems the original setting is “Obtain DNS server address automatically” (DHCP) — returning to that undoes the change completely.

Where it can go wrong

  • On a corporate or school network, a custom resolver often breaks access to internal hostnames, intranet sites and VPN resources that rely on split DNS.
  • Public Wi-Fi captive portals may fail to load until you revert to the network’s own DNS.
  • Changing resolver changes what is filtered. A family or malware-filtering resolver will block things your current one allows, and an unfiltered one will stop blocking things you may rely on.
  • Your chosen resolver sees every domain you look up. Changing DNS moves that visibility from your ISP to that provider — it does not remove it.

Step-by-step guides

Each guide covers IPv4 and IPv6 separately, distinguishes classic DNS from DNS-over-HTTPS, and ends with a check that the change worked plus the exact steps to roll it back.
