NS Record Lookup Tool
NS (Name Server) records declare which servers are authoritative for a DNS zone. If these are wrong, nothing else in DNS resolves — not the A record for the website, not the MX record for mail, nothing. Use the form below to look up the current NS records for any domain.
Why NS records matter
Domain registration and DNS hosting are two separate things. When you buy a domain, you tell the registrar which nameservers should be considered authoritative for it. Those nameservers are what the rest of the internet consults for every other DNS answer about your domain. NS records are how that delegation is expressed.
Common NS record checks
- Confirming that a domain is delegated to the correct DNS provider (Cloudflare, Route 53, DNSimple, etc.).
- Diagnosing why a domain appears “broken” — often the NS records at the registrar and at the hosting provider disagree.
- Auditing a domain during acquisition to see who really controls its DNS.
- Verifying that a nameserver migration has fully taken effect at the registry level.
Reading the result
Each row shows one authoritative nameserver hostname. A well-configured domain publishes at least two NS records on different networks for redundancy. If the NS records you see here do not match what you set at your registrar, DNS is being answered by an unexpected provider — a strong signal that something is misconfigured.
