# Managing DNS Records on Your nxtdev.xyz Subdomain

> Learn how to create, edit, and delete DNS records for your nxtdev.xyz subdomain, including host naming rules, TTL limits, and proxy options.

DNS records let you control how traffic reaches your subdomain. From the dashboard you can add any supported record type, set a custom TTL, enable Cloudflare proxying for eligible records, and delete records you no longer need — all without touching a registrar or zone editor.

## Getting to the Records page

Navigate to **Dashboard → Domains**, select your subdomain, then click **Records** in the subdomain navigation.

## Creating a record

<Steps>
  <Step title="Open the Create DNS record form">
    At the top of the Records page you will see the **Create DNS record** card. The form shows the fields relevant to the record type you select.
  </Step>

  <Step title="Choose a record type">
    Use the **Type** dropdown to select one of the supported types: A, AAAA, CNAME, TXT, MX, or SRV. The form fields update automatically to match the chosen type.
  </Step>

  <Step title="Set the Host">
    Enter a value in the **Host** field.

    * Use `@` (the default) to target the subdomain itself — for example, `alice.nxtdev.xyz`.
    * Enter a relative name to create a sub-host. For example, entering `api` on `alice.nxtdev.xyz` creates `api.alice.nxtdev.xyz`.

    Host labels must be lowercase alphanumeric and may contain `.`, `_`, and `-`. Labels cannot start or end with `.` and are capped at 63 characters.
  </Step>

  <Step title="Fill in the record-specific fields">
    Provide the **Content** (or **Target** for SRV records) and any additional fields such as Priority, Weight, or Port. See [Record Types](/dns/record-types) for the full field reference per type.
  </Step>

  <Step title="Set the TTL">
    Enter a **TTL** (time-to-live) in seconds. The minimum is **60**, the maximum is **86400**, and the default is **3600**. A lower TTL means resolvers re-query more frequently; a higher TTL reduces query volume but slows down propagation of future changes.
  </Step>

  <Step title="Enable proxying (optional)">
    For A, AAAA, and CNAME records, a **Proxied (Cloudflare)** checkbox appears. When checked, traffic routes through the Cloudflare proxy network instead of resolving directly to your origin. Proxying is not available for TXT, MX, SRV, or NS records.
  </Step>

  <Step title="Submit the form">
    Click **Create record**. The new record appears in the Records table below.
  </Step>
</Steps>

## Editing and deleting records

Each row in the Records table has two action buttons:

* **Edit** — opens the record's edit page where you can update any field.
* **Delete** — permanently removes the record. The button is disabled while delegation is enabled or the subdomain is suspended.

## Limitations and blocked states

<Note>
  When NS delegation is enabled for your subdomain, the DNS editing form is hidden and all records become read-only. To make changes, go to **Nameserver Settings** and remove the delegation first.
</Note>

<Warning>
  If your subdomain is suspended, DNS changes are blocked until the suspension is lifted. The Delete button is also disabled in this state.
