To complete zone configuration and initiate traffic flow through the NS1 platform, you must update the nameserver delegation for your domain(s) to point to NS1's authoritative nameservers assigned to the zone. Refer to this article to learn more about NS1 nameserver assignments. Depending on the type of zone and your configuration, you will need to update the delegation at the domain registrar, primary DNS provider, or parent zone.
After configuring a zone and its records, follow the instructions below to update the nameserver delegation for the corresponding domain.
Warning: Do not update the registrar until you are ready to send DNS traffic to the new nameservers. If you are undergoing a large migration to the NS1 platform or between NS1 services, adhere to the guidance provided by the NS1 team before updating the registrar.
-
Locate and record the NS1 nameservers listed as answers within the zone's nameserver (NS) record. Refer to Locating assigned nameservers.
-
Depending on the type of zone and your configuration, update the nameserver delegation at the domain registrar, primary zone, or parent zone.
-
For primary zones — as in, NS1 is the primary DNS provider for the domain — update the nameservers (NS record) at the domain registrar. Refer to the documentation provided by your registrar for instructions.
-
For secondary zones, update the NS record within the primary zone to include (not replace) NS1 nameservers. Refer to Configuring NS1 as a secondary DNS provider.
-
For parent and child zones or sub-delegations, refer to Subdelegations and child zones for instructions on where to update the delegation depending on the details of your configuration.
