What is Nameserver Lookup?

Nameserver Lookup checks the NS records for a domain. NS records identify the authoritative DNS servers responsible for that zone. They are often the fastest way to confirm whether a domain is using Cloudflare, Route 53, GoDaddy, Namecheap, or another DNS provider.

How to Use Nameserver Lookup

1

Enter a domain such as example.com.

2

Click Find NS.

3

Review the nameserver hostnames and TTL values.

4

Copy one nameserver or download the full report.

Common Use Cases

  • Confirming a registrar nameserver change has taken effect.
  • Identifying the DNS provider responsible for a domain.
  • Auditing domains before migrating DNS zones.
  • Checking whether delegated nameservers match the expected provider.
  • Troubleshooting DNS changes that are being made in the wrong provider account.

Example Input and Output

Nameserver records for a domain.

Domain
cloudflare.com
NS records
NS: ns3.cloudflare.com
NS: ns4.cloudflare.com

How This Tool Works

The tool sends an NS query to the DNS proxy, receives the resolver response, strips trailing DNS dots from nameserver hostnames, and displays TTL values.

Privacy Note

The queried domain is sent to the WebToolsPlanet DNS proxy and Cloudflare DNS-over-HTTPS. Public NS lookups are visible to the resolver.

Frequently Asked Questions

What is an NS record?
An NS record names the authoritative DNS server for a domain zone. Resolvers use it to know where the domain records are managed.
Why are nameserver changes slow?
Resolvers cache NS records according to TTL values. Registrar and registry updates can also take time to appear globally.
Can different subdomains have different nameservers?
Yes. A zone can delegate a subdomain to separate nameservers by publishing NS records for that subdomain.
Does this show every DNS record?
No. This page only checks NS records. Use the full DNS Lookup tool to inspect A, AAAA, MX, TXT, CNAME, SOA, and PTR records.
Is this lookup server-side?
Yes. DNS queries run through a server-side DNS-over-HTTPS proxy because browsers do not expose raw DNS lookups.
