Nameserver Lookup
Identify authoritative nameservers responsible for resolving domain queries and detect the active registrar hosting infrastructure.
Frequently Asked Questions
A registrar is the company where you registered the ownership of your domain (e.g. GoDaddy). A DNS host (identified by NS records) is the service provider hosting the active zone records that direct traffic to web servers.
Most registrars recommend setting at least two authoritative nameservers for redundancy. High-availability platforms (like AWS Route 53) often provision four unique nameservers across separate physical networks.
