How to use DNS Checker
Use the DNS Checker to inspect domain records when setting up hosting, email, verification, redirects, or technical SEO. Check A, AAAA, MX, TXT, NS, CNAME, and other records so you can confirm that a domain points to the right services and troubleshoot configuration issues.
Step 1: Enter the domain
Type the hostname you are troubleshooting (with or without www, matching what users hit).
Step 2: Inspect record types
Review A/AAAA, MX, TXT, CNAME, and related records for mismatches after a migration or DNS change.
Step 3: Compare with expected values
Check TTL and targets against your DNS host panel, then wait for propagation if you just published updates.

Why use DNS Checker?
DNS mistakes take sites offline even when servers are healthy. A checker shows what the public tree currently returns so you can fix records faster.

Practical tips
- Propagation is not instant—low TTLs help during planned cuts.
- Verify both apex and www if you use redirects between them.
- SPF/DKIM TXT records matter as much as A records for email deliverability.
