Who runs the domain's DNS?
Enter a domain to see the authoritative nameservers (NS) that manage its DNS.
About this tool
The NS record shows which nameservers are the official authority for a domain's DNS records. When you move a domain between registrars or add a CDN, these are the records that change. Checking NS is the first step in diagnosing DNS issues.
