What is an NS record?

An NS (Name Server) record identifies the authoritative DNS servers that contain the master DNS records for a domain name.

How many NS records should a domain have?

A domain should have at least two authoritative nameservers located on separate networks for redundancy.

What happens if NS records are misconfigured?

If your domain's NS records are invalid or point to unreachable servers, your domain will stop resolving on the internet, taking down your web app and email.
