DNS Lookup
Look up the public DNS records for any domain and verify where traffic, email, and verification records point.
Free DNS Lookup Tool
Use this free DNS lookup tool to inspect the records behind a domain before migrating hosting, debugging email delivery, adding analytics verification, or checking a launch configuration. It checks common record types that affect websites, email, search, and infrastructure.
When to use a DNS lookup
DNS is the routing layer behind your website. A quick lookup helps confirm whether a domain points to the right server, whether email records are configured, and whether TXT verification records are visible to external services.
- - Check A and AAAA records before pointing traffic to a new host.
- - Verify MX records when email delivery breaks after a migration.
- - Confirm TXT records for search console, analytics, SPF, DKIM, and DMARC.
Why DNS matters for analytics
Analytics data quality depends on a working site, correct redirects, and stable hostnames. DNS issues can create traffic drops that look like product problems, so checking records is often the first step when visits suddenly change.
Frequently Asked Questions
What DNS records does this tool check?
It checks common public DNS records including A, AAAA, MX, NS, TXT, CNAME, CAA, and SOA records when they are available for the domain.
Why are my new DNS records not showing yet?
DNS changes can take time to propagate because resolvers cache previous answers based on TTL values. Some changes appear within minutes, while others can take several hours.
What is the difference between A and AAAA records?
A records point a domain to an IPv4 address. AAAA records point a domain to an IPv6 address. Many modern sites publish both.
Can DNS problems affect website analytics?
Yes. If a domain points to the wrong host, fails intermittently, or sends users through unexpected redirects, analytics can show sudden drops, duplicate hostnames, or unusual traffic paths.
Is this DNS lookup tool free?
Yes. You can check public DNS records for any domain without creating an account.
