Frequently Asked Questions
What is a DNS record?
A DNS record is an instruction stored in the Domain Name System that tells the internet how to handle requests for a domain — such as which IP address it points to, or which servers handle its email.
What are the most common DNS record types?
A (points to an IPv4 address), AAAA (IPv6 address), MX (mail server), CNAME (alias to another domain), TXT (text data, often used for verification), and NS (nameservers).
Why would I need to check a domain's DNS records?
Common reasons include troubleshooting website or email delivery issues, verifying DNS changes have propagated, confirming domain ownership setup, or auditing a domain's configuration.
Is this tool free to use?
Yes, completely free with no signup, no limits and no software to install.
Is my data saved anywhere?
No — lookups run on request and are not stored or linked to you.
Why don't my DNS changes show up immediately?
DNS changes take time to propagate globally due to caching (TTL settings) at various points across the internet — this can range from minutes to 48 hours depending on the record's TTL value.
What is an MX record used for?
MX (Mail Exchange) records specify which mail servers are responsible for receiving email for a domain, and in what priority order if multiple servers are configured.
What is a TXT record commonly used for?
TXT records store arbitrary text data, commonly used for domain ownership verification (like Google Search Console), SPF/DKIM email authentication, and other configuration needs.
Can I check DNS records for any domain, or only my own?
You can check the public DNS records for any domain, since DNS records are publicly queryable by design — this doesn't require ownership or authentication.
Is this useful for verifying SPF/DKIM email authentication setup?
Yes — checking TXT records is a common step when setting up or troubleshooting SPF, DKIM, and DMARC email authentication for a domain.
The DNS Records Checker retrieves a domain's DNS records — A, MX, TXT, NS, CNAME, and others — revealing exactly how that domain routes traffic and email.
Why DNS Records Are the Domain's Instruction Manual
DNS records tell the internet how to handle a domain: which server hosts the website, which mail servers accept email for it, and which third-party services (like a CDN or verification service) have been authorized to interact with it. Checking these records directly reveals a domain's technical configuration without needing any backend access.
Key Record Types and What They Reveal
- A record — points the domain to an IPv4 address, the core record determining which server hosts the website.
- MX record — specifies which mail servers handle email for the domain, revealing the email provider (Google Workspace, Microsoft 365, or a custom mail server).
- TXT record — often used for domain ownership verification and email authentication protocols like SPF and DKIM, which help prevent email spoofing.
- NS record — identifies which nameservers are authoritative for the domain, revealing the DNS provider managing the domain's records.
Common Use Cases
Verifying DNS changes have propagated after switching hosting or email providers, diagnosing why email isn't being delivered correctly, and auditing a domain's configuration before a migration or security review.
