# DNS User Guide

> Manage DNS zones, record sets, reverse DNS, and record types in Xloud DNS. Learn to create zones, populate records, configure PTR entries, and.

<p style={{ fontSize: '1.25rem', fontWeight: 700, marginBottom: '0.75rem' }}>Overview</p>

Xloud DNS provides authoritative DNS management for your private cloud domains. Create
zones, populate them with record sets, and manage reverse DNS for IP-to-hostname
resolution. DNS records integrate with your compute and networking resources to support
service discovery, email routing, and compliance requirements.

<Note>
  **Prerequisites**

  * An active Xloud account with appropriate permissions
  * Access to the **Xloud Dashboard** or CLI configured with credentials
  * API credentials sourced (`source openrc.sh`)
</Note>

<p style={{ fontSize: '1.25rem', fontWeight: 700, marginBottom: '0.75rem' }}>Key Concepts</p>

| Concept        | Description                                                                                                    |
| -------------- | -------------------------------------------------------------------------------------------------------------- |
| **Zone**       | An authoritative DNS domain boundary (e.g., `app.example.com.`). Contains all record sets for that domain      |
| **Record Set** | One or more DNS records sharing the same name and type — e.g., two A records for `www`                         |
| **Nameserver** | The resolver authoritative for the zone. Clients send queries here to resolve names                            |
| **PTR Record** | Reverse mapping — resolves an IP address back to a hostname. Required for mail servers and audit logging       |
| **SOA Record** | Start of Authority — defines zone parameters including serial number, refresh interval, and primary nameserver |
| **TTL**        | Time-to-Live — how long resolvers cache a record before re-querying. Lower values propagate changes faster     |

<Note>
  DNS zones must be properly delegated before public resolvers can use them. For internal
  zones, ensure your clients are configured to query the Xloud DNS service nameservers.
