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.

  • 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.
