What is a DNS checker?

A DNS checker is a tool that queries DNS servers worldwide to verify that your domain's DNS records have propagated correctly. It shows you which servers have updated DNS information and which are still showing old records.

How long does DNS propagation take?

DNS propagation typically takes 24-48 hours to complete globally, but can sometimes take up to 72 hours. The actual time depends on TTL settings, ISP caching, and the DNS provider. Use our DNS propagation checker to monitor real-time status.

What DNS record types can I check?

Our free DNS checker supports all common record types: A records (IPv4), AAAA records (IPv6), MX records (mail), CNAME records (aliases), TXT records (SPF, DKIM, verification), NS records (nameservers), and more.

Is this DNS checker free?

Yes, our DNS checker is 100% free with no signup required. Check unlimited domains across 50+ global DNS servers. We also offer premium features like scheduled monitoring and alerts for enterprise users.

DNS Record Types Explained

A Record (Address Record)

Maps a domain name to an IPv4 address. The most common DNS record type. Example: example.com → 93.184.216.34

AAAA

AAAA Record (IPv6 Address)

Maps a domain to an IPv6 address. Essential for modern internet infrastructure. Example: example.com → 2606:2800:220:1:248:1893:25c8:1946

MX Record (Mail Exchange)

Specifies which mail servers receive email for your domain. Critical for email delivery. Example: 10 mail.example.com

CNAME

CNAME Record (Canonical Name)

Creates an alias from one domain to another. Used for subdomains. Example: www.example.com → example.com

TXT

TXT Record (Text Record)

Stores text information. Used for SPF, DKIM, DMARC email authentication, and domain verification (Google, Microsoft).

NS Record (Name Server)

Specifies the authoritative DNS servers for your domain. Example: ns1.example.com, ns2.example.com

DNS Checker FAQ

What is DNS propagation? expand_more

DNS propagation is the process of updating DNS records across all DNS servers worldwide. When you make changes to your DNS (like pointing your domain to a new server), these changes need to spread to DNS servers globally. This typically takes 24-48 hours but can vary based on TTL settings.

Why isn't my DNS propagating? expand_more

Common reasons for slow DNS propagation: 1) High TTL values on old records - reduce TTL before making changes, 2) ISP caching - some ISPs cache DNS longer, 3) Incorrect records - verify your new records are correct, 4) Registrar delays - some registrars take time to push changes. Use our DNS checker to monitor propagation in real-time.

How do I check my DNS records? expand_more

Enter your domain in our DNS checker above and select the record type you want to check (A, MX, TXT, etc.). We'll query 50+ DNS servers worldwide and show you the current records. You can also use command-line tools like nslookup or dig, but our tool is faster and shows global results.
