NS Overview

NS (Name Server) records specify the name servers used for a domain or subdomain. Name servers for the root domain (like are set directly on the domain’s registrar, as well as through NS records.

Additional NS records can be created if you wish use a subdomain with a different DNS provider or manage it as a separate Domain (zone file) in Linode’s DNS Manager.

The order of NS records does not matter. A random NS record for a domain will be provided when the domain is queried. If one name server fails to respond, another one will be queried.


  • Name Server: The name server you wish to use. This could be name server corresponding with a third-party DNS service. If you wish to still use Linode’s DNS Manager but manage the subdomain as a separate Domain (zone file), enter Linode’s name servers.

  • Subdomain: The subdomain that you wish to manage as a separate Domain (zone file) or through another DNS provider.

    • Enter a string that’s 1-63 characters in length and contains only letters, numbers, and underscores. Hyphens can also be used, but the string cannot start with one.
  • TTL (Time To Live): The length of time that DNS resolvers should store the DNS record before revalidating it with Linode’s name servers. Setting the TTL to 5 minutes is recommended for many use cases. If Default is selected, the TTL is set to 24 hours.
