What is an NS record?

NS records delegate a domain to specific authoritative nameservers.

Why NS records matter

They control which servers answer DNS queries and where DNS changes are managed.

When to update NS records

Update NS records when migrating DNS providers or changing authoritative infrastructure.

Frequently Asked Questions

How many NS records should I have?

At least two for redundancy. Many providers recommend two to four nameservers.

Why do NS records look different at registrar vs DNS?

Registrar NS records delegate the zone, while DNS NS records live inside the zone itself.

How long do NS changes take to propagate?

Propagation depends on TTL and registrar updates, often taking several hours.
