Follow the instructions below to create a new DNS zone in the NS1 portal. Alternatively, you can import a zone file from your existing or previous DNS provider.
- Navigate to DNS > Zones to view a list of zones associated with your account.
- Click the pink "add" (+) icon to display the "Add zone" screen.
- Enter the fully qualified domain name (FQDN) associated with this zone.
- Optionally, begin typing the name of an existing DNS view. When you associate the zone with a DNS view, you must include a zone name (i.e., zone handler) which is a nominal label applied to the zone, allowing you to have multiple zone names pointing to the same FQDN. Refer to Configuring NS1 DNS views for more information.
NOTE: In order to enable TSIG on a primary zone, you must associate it with a DNS view. The DNS view must contain an access control list with a TSIG object defined.NOTE: Currently, zones within the Managed DNS or Managed DNS for China networks cannot be associated with a DNS view.
- Select a network with which to associate the zone.
- Select the type of zone you are creating.
- Normal setup - Creates a primary zone within the NS1 platform.
- Zone file import - Allows you to import an existing zone file. Refer to Importing zone files.
- Secondary zone - Creates a secondary zone. Refer to Configuring NS1 as a secondary provider (a.k.a., Creating secondary zones).
- Linked zone - Creates a linked zone (i.e., vanity domain). Refer to Creating a linked zone.
- Edit the configuration settings based on the type of zone you are creating. If you are creating a primary zone, you must specify the TTL values and configuration settings below. If you are creating a secondary, linked, or imported zone, refer to the articles referenced in the previous step for details.
For primary zones, specify the following TTL values:
Note: Refer to Best practices: TTL configuration.
- SOA TTL (seconds) - This is the time-to-live (TTL) of the zone’s SOA (start of authority) record.
- Refresh(seconds) - This is the interval at which secondary servers (secondary DNS) are set to request a refresh of the zone from the primary server.
- Retry (seconds) - This is the number of seconds that the secondary name servers should wait before retrying a request to refresh the zone if the initial refresh failed.
- Expiry (seconds) - If Refresh and Retry fail repeatedly, this is the time period after which the primary should be considered down and no longer authoritative for the given zone. After this period of time, if the primary has not responded then NS1 will no longer answer requests for this zone.
- NX TTL (seconds) - This indicates how long a resolver may cache the negative answer in the event that a DNS query results in a non-existent domain (NXDOMAIN) response.
- Click Save Zone. The new zone appears in the list and is auto-populated an NS record which specifies the associated name server.
Next, refer to Creating a DNS record for instructions on creating DNS records within a zone.
