Tool
DNS Check
Look up DNS records for a domain and spot common setup problems.
Best for
- Verifying domain setup after DNS changes
- Checking A / CNAME / MX / TXT records quickly
- Troubleshooting email and website pointing issues
What we check
- A, AAAA, CNAME, MX, TXT, NS records
- Domain extracted from URLs (if you paste a full link)
- Basic error classification if the lookup fails
Paste a domain (example.com) or a full URL — we’ll automatically use the domain part.

Tip: If a provider’s status is green but your app is failing, it’s often DNS, TLS, redirects, or headers. Browse Status Pages.
Can I paste a full URL?
Yes. DNS Check extracts the hostname automatically.
If you paste https://example.com/some/path, it will run against example.com.
What should I check for email deliverability?
Common DNS pieces include MX records for mail routing, and TXT records for SPF/DKIM/DMARC.
If email is failing, confirm the provider’s required records match what’s published.
Why do DNS changes take time?
DNS is cached across resolvers.
Propagation time depends on TTL settings and upstream caches.
