What is a DNS NS Record? | Definition, Function & Example
A DNS NS Record (Name Server Record) specifies the authoritative name servers for a domain. These records indicate which servers are responsible for handling DNS queries for a domain like example.com. Without proper NS records, your domain cannot resolve correctly on the internet.
Key Functions of a DNS NS Record:
- Delegates domain control: Points to the name servers that manage DNS records for your domain.
- Enables DNS resolution: Ensures users can access your website, email, and other online services.
- Supports DNS redundancy: Typically includes multiple name servers for failover and performance.
Example of a DNS NS Record:
example.com. IN NS ns1.exampledns.com.example.com. IN NS ns2.exampledns.com.
Best Practices for DNS NS Records:
- Use at least two geographically diverse name servers.
- Ensure consistency: your registrar’s and DNS provider’s NS records must match.
- Monitor and test DNS resolution regularly to avoid downtime.
