# Overview

The Domains section is for creating and managing domains for use in VM Essentials. Domains are used for setting FQDNs, joining Domains, and creating DNS records. The Domains section is also a multi-tenant endpoint for managing domain settings across multiple tenants.

- Domains are synced in from Cloud, DNS and Network Integrations. Domains can also be user created.
- Active Domains are available for selection in the Domain dropdown when provisioning an Instance
- Default Domains can be set for Clouds and Networks in their Advanced Options sections.
- Images can be flagged to Auto-Join Domains in the Infrastructure  >  Network  >  Domains section
