Free checks for your website, domain and email
Free DNS checker: records, name servers and DNSSEC
Enter a domain to see what visitors’ browsers get from public DNS: the addresses it points to, the name servers that answer for it and whether its DNSSEC signatures validate.
What this checker looks at
The domain’s address records (A and AAAA), its name servers and whether they answer, its DNSSEC signatures as validating resolvers see them, and its CAA records.
What a failing result means
No address records means browsers find nothing at that name. Name servers that do not answer, or a domain missing from DNS, take everything on the domain offline, email included. Broken DNSSEC makes validating resolvers refuse to answer, so most visitors fail to reach the site.
How to fix it
Restore the missing record at your DNS provider, point the domain at name servers that answer, or repair DNSSEC by updating or removing the DS record at your registrar. A change can take up to the record’s TTL to reach everyone.
Questions people ask
- Why does my site work for me but not for others?
- Your device or network may still hold an old answer in its cache. Public DNS shows what new visitors get, which is what this check reads.
- Can Xovris fix DNS for me?
- For domains on Cloudflare, yes: connect the domain on Builder and Xovris restores a broken record from its last verified version, then re-runs the failed check to prove the fix.
