Understanding Your DNS

DNS (Domain Name System) is like the phonebook of the internet. It translates human-readable domain names into IP addresses that computers use to communicate.

Fast DNS = faster website loading times
Encrypted DNS (DoH/DoT) = better privacy
DNSSEC = protection against DNS spoofing
DNS Leak = your DNS queries may be exposed

Frequently Asked Questions

What is a DNS server?

A DNS (Domain Name System) server translates human-readable domain names like "google.com" into machine-readable IP addresses like "142.250.80.46". Without DNS, you would need to memorize IP addresses for every website you visit.

How can I tell which DNS server I'm using?

This tool detects your DNS servers by analyzing how your browser resolves domain names through public DNS-over-HTTPS (DoH) endpoints. It also checks your public IP and ISP information. Click "Run Detection" above to get started.

What is DNS over HTTPS (DoH)?

DNS over HTTPS (DoH) encrypts your DNS queries using the HTTPS protocol, preventing third parties from intercepting or tampering with your DNS traffic. This enhances privacy and security by hiding your browsing activity from ISPs and potential eavesdroppers.

What is a DNS leak?

A DNS leak occurs when your DNS queries are sent to an unintended DNS server, often your ISP's server, even when you're using a VPN or custom DNS settings. This exposes your browsing history to parties you intended to avoid.

Should I change my DNS server?

Switching to a public DNS provider like Cloudflare (1.1.1.1), Google (8.8.8.8), or Quad9 (9.9.9.9) can improve speed, security, and privacy. Cloudflare focuses on speed and privacy, Quad9 blocks malicious domains, and Google offers reliability. Test them above to find the fastest for your location.

What is DNSSEC?

DNSSEC (Domain Name System Security Extensions) adds cryptographic signatures to DNS records, ensuring that the response you receive is authentic and hasn't been tampered with. It protects against DNS cache poisoning and man-in-the-middle attacks.

How accurate is this DNS detection tool?

This tool uses multiple DNS-over-HTTPS endpoints and IP detection services to infer your DNS configuration. While highly indicative, browser-based detection has limitations. For the most accurate results, check your device's network settings or router configuration.

Why do different DNS providers show different speeds?

DNS response time depends on the physical distance between you and the DNS server, network congestion, and server load. A provider with servers closer to your geographic location will generally respond faster. Our performance test measures actual round-trip times from your browser.

Can my ISP see my DNS queries?

Yes, if you use your ISP's default DNS servers, they can log every domain you visit. Encrypted DNS (DoH or DoT) prevents your ISP from reading your DNS queries, though your ISP can still see which IP addresses you connect to via traffic analysis.

What's the difference between DNS and a VPN?

DNS translates domain names to IP addresses, while a VPN encrypts all your internet traffic and routes it through a remote server. Changing DNS improves speed and may add security, but it doesn't hide your IP address or encrypt your traffic like a VPN does.

How do I change my DNS settings?

You can change DNS settings at the device level (Windows, macOS, iOS, Android) or at the router level to affect all connected devices. Go to your network settings, find the DNS configuration, and replace the default servers with your preferred public DNS addresses like 1.1.1.1 or 8.8.8.8.

Is this tool safe to use?

Absolutely. All detection is performed client-side in your browser. We don't store, log, or transmit any of your DNS data to external servers beyond the standard DNS-over-HTTPS queries needed for detection. No personal data is collected.

DNS Record Types Explained
Record Type Full Name Purpose Example
A Address Record Maps a domain to an IPv4 address example.com → 93.184.216.34
AAAA IPv6 Address Record Maps a domain to an IPv6 address example.com → 2606:2800:220:1:248:1893:25c8:1946
CNAME Canonical Name Aliases one domain to another www.example.com → example.com
MX Mail Exchange Directs email to mail servers example.com → mail.example.com (priority 10)
NS Name Server Specifies authoritative DNS servers example.com → ns1.example.com
TXT Text Record Stores text data (SPF, DKIM, verification) example.com → "v=spf1 include:_spf.google.com ~all"
SOA Start of Authority Contains administrative zone information Includes serial, refresh, retry, expire, and TTL values
