About the Nameserver Lookup

Find which nameservers a domain is delegated to, and confirm the delegation at the registry matches what the nameservers themselves claim.

• Authoritative nameservers for the domain
• Reveals mismatches between registry and zone
• First check when a DNS change has no effect

Frequently asked questions

Why do my DNS changes have no effect?

Often the domain is delegated to different nameservers than the ones you edited. This shows which servers are actually authoritative.

How many nameservers should a domain have?

At least two, on separate networks, so the domain still resolves if one goes down.
