DNS NS Record Lookup - Find Authoritative Nameservers
Look up NS records to identify the authoritative nameservers for any domain. Verify DNS delegation and troubleshoot nameserver configuration issues.
Understanding NS Records
NS (Name Server) records specify which DNS servers are authoritative for your domain. These servers contain the actual DNS records for your domain.
Understanding This Tool
What It Does
Find the nameservers (NS records) responsible for a domain. Nameservers are the authoritative DNS servers that handle all DNS queries for a domain.
Understanding the Results
- Nameserver Hosts: The DNS servers responsible for the domain
- Server Names: Hostnames of each nameserver
- Server IPs: IPv4 and IPv6 addresses of nameservers
- TTL: Time to live for the NS records
Common Use Cases
- DNS Provider Change: Verify new nameservers are properly configured
- Domain Registration: Check which nameservers manage a domain
- DNS Delegation: Understand how DNS authority is delegated
- Troubleshooting: Diagnose DNS resolution issues
- Verification: Confirm DNS changes have taken effect
Pro Tips & Best Practices
- Multiple Nameservers: Domains typically have 2-4 nameservers for redundancy
- Registrar vs Hosting: Domain registrar controls which nameservers are used
- Propagation: NS record changes can take 24-48 hours to propagate
How this tool works: This tool runs in your browser and on our server in real time. Depending on the tool, results are computed directly from the input you provide or retrieved from live, authoritative data sources at the moment you run a lookup. We do not sell your data, and your lookups are kept private — any history shown here is stored only on your device.
