What is a DNS zone
The DNS zone is the domain you delegate to Gcore authoritative NS servers. The following values can be used as the DNS zone:
- a second-level domain (testdomain.com),
- a third-level domain (store.testdomain.com, blog.testdomain.com, etc.),
- or a higher-level domain (sales.store.testdomain.com).
When the DNS zone creation is completed, you can set the DNS records of your domain in non-advanced and advanced modes.
Manage a DNS zone
Create a DNS zone
1. Go to the DNS section and click the Add zone button.
2. Enter a domain name for the DNS zone and click Confirm.
3. Review existing DNS records, and edit, delete, or add new records if necessary. Click Confirm.
4. Go to your domain registrar account, replace the current nameservers with the Gcore Name Servers (ns1.gcorelabs.net and ns2.gcdn.services), and click Confirm.
The created DNS zone will be displayed in the All zones section.
Edit a DNS zone
1. In the All zones section, click the three dots icon next to the desired DNS zone and select Settings.
The pop-up opens. Configure it according to the guide below and click Save changes. Configurations will be applied to the SOA record of this zone.
- Domain name. This parameter cannot be edited. Create a new zone with the required domain name following the instructions above.
- Negative TTL. This parameter is the time, in seconds, for which a negative response is cached. For example, a recursive DNS server requests an A-record for your domain, but that record does not exist on the authoritative NS servers. Even if you add the A record after, the DNS servers will still return a negative answer for the time specified in the "Negative TTL" field.
- Primary DNS (available only for Enterprise tariff). In this parameter, you can specify the primary NS server that contains the information about all domain records.
- Contact (available starting from the Pro tariff). In this parameter, you can specify the administrator's email address responsible for managing the DNS zone.
Delete a DNS zone
1. In the All zones section, click the three dots icon next to the desired DNS zone and select Delete zone.
2. Confirm the deletion in the pop-up window.
