DNS lookup
Enter a domain to list its records, or an IP address to see its reverse PTR record.
About this tool
The Domain Name System (DNS) is the internet's directory: it turns your site name into the IP address of the server that hosts it and decides where your email is delivered. This tool shows the records as a public resolver sees them right now, so you know whether your last change has arrived or is still propagating.
An A record points to the site's IPv4 address and AAAA to its IPv6 address, CNAME makes one name follow another, MX names the mail servers and their priority, TXT carries ownership checks and SPF/DMARC policies, and CAA lists which authorities may issue SSL certificates.

Frequently asked questions
Why is my new record not showing?
Changes propagate according to the old record's TTL, from minutes up to 48 hours. Check again once the TTL has passed.
Does the tool change anything?
No, it is read-only. To edit records use your hosting control panel or domain management in the client area.
