What are DNS records, and why check them?
DNS (Domain Name System) records are the instructions that tell the internet how to route traffic for your domain — which server hosts your website (A/AAAA), which servers handle your email (MX), which services are authorized to send email on your behalf (TXT/SPF), and which name servers are authoritative for the domain (NS).
A single missing or misconfigured record can take down email delivery, break a subdomain, or leave a domain vulnerable to email spoofing — and because DNS changes can take time to propagate, problems aren't always obvious right away.
This tool queries the live DNS records for any domain — A, AAAA, MX, NS, TXT, and CNAME — so you can confirm a change has propagated correctly, diagnose a delivery problem, or just see how another site's infrastructure is set up.
Frequently asked questions
- Why would I check another site's DNS records?
- To see how their infrastructure is set up — which CDN or host they're using, how their email is routed — which is common when researching a competitor's stack or diagnosing your own migration.
- I just changed a DNS record — why doesn't this tool show the new value yet?
- DNS changes propagate based on each record's TTL (time-to-live) and can also be cached by resolvers around the internet; it can take anywhere from minutes to 48 hours to fully propagate.
- What's a TXT record used for?
- TXT records hold arbitrary text data attached to a domain — most commonly used for email authentication (SPF, DKIM, DMARC) and to verify domain ownership with third-party services.
- What's the difference between an A and a CNAME record?
- An A record points a domain directly to an IP address. A CNAME record points a domain to another domain name instead, which is useful when the target's IP might change.
