# DNS Monitoring

#### Operational Status Overview

<figure><img src="/files/pmlCvp8OMLtZ6C1HPU5l" alt=""><figcaption></figcaption></figure>

At the top of the page, you’ll see a live operational status for the domain:

> **Operational**\
> \&#xNAN;*DNS records last changed on 12/06/2025, 22:26*

This tells you:

* All nameservers are responding correctly
* No DNS misconfigurations have been detected
* The last time your DNS records were modified

***

#### Authoritative Nameservers

Varsuite Core checks and displays your current **nameserver configuration**. In the example shown:

<figure><img src="/files/McneYmJYz4qV9GhTmDqF" alt=""><figcaption></figcaption></figure>

| Nameserver           | Status      |
| -------------------- | ----------- |
| `ns1.varsuite.co.uk` | Operational |
| `ns2.varsuite.co.uk` | Operational |
| `ns3.varsuite.co.uk` | Operational |
| `ns4.varsuite.co.uk` | Operational |

This helps confirm:

* Your DNS is properly delegated
* All expected nameservers are online and synchronised
* There's no propagation lag or DNS outage

***

#### DNS Record Breakdown

Below the nameservers, you’ll find a full list of active DNS records for the domain as seen by the selected authoritative server.

| Record Type     | Description                                                                            | TTL    |
| --------------- | -------------------------------------------------------------------------------------- | ------ |
| **A Record**    | IPv4 address for the domain (e.g. `185.151.30.202`)                                    | 1 hour |
| **AAAA Record** | IPv6 address (e.g. `2a07:7800:202::`)                                                  | 1 hour |
| **MX Record**   | Mail exchange server used for email routing (e.g. `mail.protection.outlook.com`)       | 1 hour |
| **TXT Records** | Used for SPF, DKIM, DMARC, and domain verification (e.g. Google, Apple, Mailjet, M365) | 1 hour |

Each DNS entry includes:

* **Type** (A, AAAA, MX, TXT, etc.)
* **Value** (IP address, mail server, verification code, etc.)
* **TTL** (Time to live, in seconds)

You can use this to:

* Spot misconfigured SPF records
* Confirm new mail routing setups
* Monitor recent record changes (great for migrations)
* Audit for missing or unexpected records

***

#### Use Cases

* DNS audits during domain handovers or client onboarding
* Ensuring SPF, DKIM, and DMARC records are correct for mail deliverability
* Diagnosing email routing issues or CDN/IP propagation problems
* Keeping track of DNS changes for compliance and rollback

***

#### Learn What Each Record Means

Varsuite includes a direct link to documentation explaining what each DNS record does and how it affects your domain. Ideal for onboarding junior staff or training new hires.

> 🛈 *“Learn more about what each of these DNS records mean in our docs”*

***

#### Best Practices

* Review DNS before and after site migrations
* Set alert rules for unexpected DNS changes or TTL drops
* Monitor TXT records regularly to ensure email deliverability compliance

***

With Varsuite Core DNS Monitoring & Checks, you gain continuous oversight over one of the most critical (and commonly overlooked) parts of your infrastructure. Stay in control of your records, protect email delivery and avoid costly DNS mistakes before they go live.
