How to check DNS records
Understand the DNS records that help a domain route web traffic and email.
The short answer
Use DNS Lookup to inspect the records returned for a domain, then compare them with the service you are configuring.

- Enter the domain without a path.
- Run the lookup.
- Review A or AAAA records for web routing, MX for email, and TXT for verification or policy values.
- Check nameservers and TTL context when troubleshooting propagation.
Technical details
- DNS is distributed and cached, so different resolvers can return different answers for a period after a change.
Common mistakes
- Adding a path or protocol to a domain lookup.
- Deleting an existing record before confirming the provider's required value.
- Expecting an instant global update.
Limitations
- A lookup shows returned records; it does not prove that a service is configured correctly or reachable from every network.
