# Creating a DNS Group

> **Applies to:** SBC 3.1, 3.3

\*\*Note: \*\* This article describes how to configure a DNS Group, which is not the same as creating a [DNS server group for the Linux host](/configuration/web-portal-3-3/system/services/set-dns.md).

You can create one or more DNS Groups to manage the DNS Server traffic of Fully Qualified Domain Names (FQDN).

1- Click **DNS** in the navigation panel

2- Click **Create New DNS Group**

![dns group 1](https://docs.telcobridges.com/w/images/c/ce/Dns_group_1.png)

3- Enter a name for the DNS Group.

* Click **Create**

![dns group 2](https://docs.telcobridges.com/w/images/0/0e/Dns_group_2.png)

4- Verify that the **"DNS group was successfully created"** message appears

5- Create a DNS Server for the DNS Group.

* Click **Create New DNS Server**.

6- Configure the DNS Server.

* Enter a name for the DNS server.
* Enter an IP address for the server.
* Select a Local IP interface. This is the interface through which the DNS requests will be transmitted.
* Click **Create**.

7- Verify that the **"DNS server was successfully created"** message appears

![dns group 6](https://docs.telcobridges.com/w/images/d/d9/Dns_group_6.png)

8- Select an IP interface from the list of available interfaces. The interfaces that are added will have their FQDN requests resolved by this DNS group.

* Click ![dns group 8](https://docs.telcobridges.com/w/images/8/8c/Dns_group_8.png) to move the available interface over to the **Current** list.

![dns group 7](https://docs.telcobridges.com/w/images/8/87/Dns_group_7.png)

* Click **Create**.

The DNS Group with the new DNS Server and DNS Local entries are displayed.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

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

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://tmediadocs.telcobridges.com/other-pages/operations/creating-a-dns-group.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
