# Checking DNS Propagation for Your nxtdev.xyz Records

> Use the built-in propagation checker to see what public resolvers return for your records, and learn what to do when a record hasn't appeared yet.

After you create or update a DNS record, public resolvers around the world need to pick up the change before it takes effect everywhere. nxtdev.xyz includes a built-in propagation checker that queries live DNS resolvers on demand so you can verify a record without leaving the dashboard.

## How the propagation checker works

The **Check propagation** button in the Records table performs a live DNS lookup against Cloudflare's public resolver. It queries the fully qualified domain name and record type you saved, and shows you what that resolver currently returns — so you can confirm whether your record is live without leaving the dashboard.

A successful response has this shape:

```json example propagation response theme={null}
{
  "fqdn": "api.alice.nxtdev.xyz",
  "type": "A",
  "doh": {
    "Status": 0,
    "Answer": [
      {
        "name": "api.alice.nxtdev.xyz.",
        "type": 1,
        "TTL": 3600,
        "data": "203.0.113.42"
      }
    ]
  }
}
```

When `doh.Answer` contains your expected value, the record has propagated to Cloudflare's resolver.

## Checking propagation for a record

<Steps>
  <Step title="Go to the Records page">
    Navigate to **Dashboard → Domains**, select your subdomain, then click **Records**.
  </Step>

  <Step title="Find the record in the table">
    Locate the row for the record you want to verify. Each row shows the record's Type, Name, Content, TTL, and Proxy status.
  </Step>

  <Step title="Click Check propagation">
    Click the **Check propagation** button in the Actions column for that row. The dashboard sends a live query to a public DNS resolver and displays what it currently returns.
  </Step>

  <Step title="Read the result">
    If the `Answer` section contains your record's content, propagation is complete. If the response is empty or shows a previous value, the change has not yet reached that resolver.
  </Step>
</Steps>

<Note>
  Because nxtdev.xyz uses Cloudflare's authoritative DNS infrastructure, new and updated records typically propagate globally in under 60 seconds. If a record does not appear right away, wait a moment and check again.
</Note>

## What to do if a record hasn't propagated

<Tip>
  Start with the record itself before assuming a propagation delay. Open the record's edit page and confirm the host, content, and type are all exactly what you intended — a typo in the content field is the most common cause of a record appearing to be missing.
</Tip>

If the record looks correct but the propagation check still returns no answer:

1. **Wait and retry.** Most changes resolve within 60 seconds. Occasionally a resolver takes a bit longer to flush its cache.
2. **Check the TTL of the previous record.** If you replaced an existing record, resolvers that already cached the old value will hold it until the previous TTL expires.
3. **Verify the record exists in the Records table.** If the row is gone, the record may have been deleted. Re-create it and check propagation again.
4. **Confirm your subdomain is active.** Suspended subdomains block DNS changes. Check the subdomain's status on the Domains page.
