DNS record checker
See the live DNS records of a domain or subdomain, with what each one does, and whether two public resolvers already agree after a change.
How it works
Enter a name
A domain such as example.com or a subdomain such as shop.example.com.
We query public resolvers
Our server asks Cloudflare's resolver over DNS-over-HTTPS for seven record types, and Google's resolver for A, NS and MX as a second opinion.
Read the records
Each record type is listed with its TTL and a plain explanation, plus a note when something important is missing.
DNS checker: questions and answers
Resolvers keep an answer for its TTL (time to live), so a change appears once the old TTL has passed: often minutes, at most a day or two for long TTLs. If both resolvers here show the new value, most visitors see it too.
Subdomains are normally answered by the name servers of their parent domain, so they have no NS records of their own. That is expected.
It lists the certificate authorities allowed to issue SSL certificates for the domain. It is optional; without it any authority may issue one.
This tool only reads public DNS. GlobalHostia customers manage their DNS records in the client area, and our support team can help with any change.
