DNS Records Checker
DNS (Domain Name System) records map domain names to IP addresses and configure services like email (MX records), domain verification (TXT records), and content delivery (CNAME records). This tool queries DNS servers and returns all record types for a given domain, along with TTL values.
SEO, GEO & AEO: why this checklist matters
Who should use this
System administrators, developers setting up hosting or email, SEOs verifying site configurations, and anyone troubleshooting DNS propagation.
Rankings, AI answers, and citations
DNS records don't affect search rankings directly. Incorrect DNS configuration can cause your site to be unreachable, which would obviously affect rankings, indexing, and everything else. Propagation delays after DNS changes (typically 24-48 hours) can cause temporary discoverability issues.
What to verify before you ship
- Verify A record points to the correct server IP after any hosting change
- Check MX records if email delivery is failing
- TTL should be lowered before planned DNS changes to speed up propagation
- SPF and DKIM records (in TXT) affect email deliverability — keep them current

What is DNS propagation?
When you change DNS records, the update doesn't appear everywhere instantly. DNS resolvers around the world cache records according to their TTL (Time To Live) value. Full global propagation typically takes 24-48 hours, though often happens faster.
What is a CNAME record?
A CNAME (Canonical Name) maps one domain to another. For example, www.yourdomain.com might CNAME to yourdomain.com. It's also used for CDN configuration and third-party service integration.
What are SPF and DKIM records?
SPF (Sender Policy Framework) and DKIM (DomainKeys Identified Mail) are email authentication standards stored as TXT records. They tell receiving mail servers which IP addresses and signing keys are authorized to send email for your domain.
Why are there multiple A records for the same domain?
Multiple A records implement load balancing across servers. DNS returns all IP addresses and the client (or its DNS resolver) picks one, distributing traffic across servers. This is common for high-traffic sites.
