Overview

A public zone provides information to translate a domain name and its subdomains into IP addresses required for network communications over the Internet. Visitors can access your website by entering a domain name in the address box of a browser. To use DNS for public domain name resolution, create a public zone for your domain name, and add record sets to map your domain name to one or more IP addresses.

Table 1 describes the operations required for creating and managing public zones.

**Table 1** Public zone operations
Operation	Scenario	Constraints
Creating a Public Zone	Create a zone for your domain name.	Public zones are global resources. You do not need to select a region or project. Each account can have up to 50 public zones. The domain name can be a second-level domain name (for example, example.com) or one of its subdomains (for example, abc.example.com).
Managing Public Zones	Modify, delete, and view public zones.	The domain name of a created public zone cannot be modified. If a public zone is deleted, all its record sets will also be deleted.
