# DNS Checker

> Review a domain's nameservers, DNS provider, DMARC policy, and TXT records in a single scan.

## Where to find it

Select **DNS Tools** in the left navigation, then the **DNS Scanner** tab. Enter a domain and select **Check Domain**. You can scan any domain, including domains that are not in your account.

## What it returns

### Nameservers

Identifies which provider runs the domain's DNS, shown as a badge — for example **AWS Route 53** — and lists every nameserver with a **Copy** control. A **Where to update DNS records** panel links directly into that provider's console.

### DMARC Policy

Summarises the DMARC record found at `_dmarc.yourdomain.com`. The badge names the policy and colours it by how much protection it gives you, with a plain-language reading underneath — `p=none` reads "Monitor only - no action taken on failing emails", `p=quarantine` reads "Failing emails are sent to spam/junk folder". Alongside it:

| Field            | What it tells you                                              |
| ---------------- | -------------------------------------------------------------- |
| Subdomain Policy | The `sp=` value, or whether subdomains inherit the main policy |
| Percentage       | The share of mail the policy applies to                        |
| DKIM Alignment   | `relaxed` or `strict`                                          |
| SPF Alignment    | `relaxed` or `strict`                                          |
| Reports sent to  | How many addresses receive aggregate reports                   |

The full raw record appears underneath with a **Copy** control.

### TXT Records

Every TXT record on the domain, with a count and a **Copy** control on each. This is where domain-verification strings for other services appear, alongside anything else published as TXT.

### Protected by DMARCeye

When the scanned domain is monitored in your account, a confirmation panel closes the results.

## When to use it

Use this when you want the whole picture at once: before moving providers, when taking over a domain you did not set up, or as the first step in diagnosing an authentication problem.

To change records rather than read them, use the [DMARC Configurator](/dmarc-configurator).
