Domain Name System

Introduction

Integration

Name server records allow you to identify the authoritative servers for this zone. These records enable us to link the domain hierarchy. NS records in the top-level domains point to the servers for the second-level domains, and so on. NS records are mandatory because, without them, the servers for a domain would be unknown.

The format for an NS record is:

The components of the NS records are described below.

domain: This is the name of the domain for which the host specified in the server field is authoritative for.

server: This is the name of the host that provides authoritative name service for this domain.
