GreenNode introduces vDNS, a powerful DNS service designed to optimize performance, enhance security, and ensure the stability of your online infrastructure. vDNS provides fast and reliable domain name resolution, ensuring a smooth access experience for users.

### Supported DNS Record Types

vDNS fully supports common DNS record types, including:

* **A:** Points a domain name to an IPv4 address.
* **CNAME:** Creates an alias for another domain name.
* **MX:** Specifies the mail server responsible for receiving emails for the domain.
* **SRV:** Specifies the location of specific services, such as VoIP services.
* **PTR:** Maps an IP address back to a domain name (reverse DNS).
* **TXT:** Stores arbitrary text, commonly used for verification and other purposes.

### Routing Policies

vDNS provides flexible routing policies to optimize performance and user experience:

* **Simple Routing:** Simple routing that returns a set of resources in order.
* **Geolocation Routing:** Routes traffic based on the user’s geographic location, enabling traffic distribution to the nearest servers.
* **Weighted Routing (with Sticky Session):** Distributes traffic based on weights assigned to each resource. The Sticky Session feature ensures users are routed to the same resource throughout their session.

### Benefits of vDNS

* Optimized performance with globally distributed infrastructure.
* High availability with a redundant architecture.
* Strong security with DDoS protection and DNSSEC support.
* Easy management through an intuitive interface.
* Integration with the GreenNode ecosystem.
* 24/7 support from a professional technical team.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.vngcloud.vn/vng-cloud-document/vdns/announcements-and-updates.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
