This tool runs on the server.
How it works
DNS translates domain names into the information systems need to connect: IP addresses, mail servers, aliases, and more. Each record type stores a different piece of the domain's data.
This query runs on the server and returns the records along with their TTL (how long they can be cached). You can specify a particular DNS server, such as 8.8.8.8, or use the default resolver.
Use cases
- Verify propagation after creating or modifying a record.
- Check the MX records before migrating a domain's mail.
- Check SPF and DKIM (in TXT records) to diagnose email delivery problems.
- Confirm which IP a domain resolves to by querying different DNS servers.
Frequently asked questions
What is a record's TTL?
It is the time, in seconds, that resolvers can keep the record cached before querying it again. A high TTL speeds up responses but delays the propagation of changes.
What is the difference between A and CNAME?
An A record points directly to an IP address. A CNAME is an alias that points to another domain name, which in turn resolves until it reaches an IP.
Why do I see a different result than someone else?
Because of caching and propagation: after a change, different resolvers may keep returning the previous value until the TTL expires.
What are TXT records for?
They store arbitrary text. They are used mainly for SPF and DKIM (mail-sending authorization) and to verify ownership of a domain with various services.
Can I choose the DNS server for the query?
Yes. You can specify a public one such as 8.8.8.8 (Google) or 1.1.1.1 (Cloudflare). If you leave the field empty, the default resolver is used.
