# Organization Domain

> Learn how to set and modify your organization's dedicated domain in the YiDA workbench, including a feature comparison across Free, Basic, Professional, and Dedicated editions. This page also covers the basic concepts of domains, along with the steps and considerations for modifying your organization's dedicated domain.

| **Feature**                   | **Free plan** | **Basic edition** | **Professional edition** | **Dedicated edition** |
| ----------------------------- | ------------- | ----------------- | ------------------------ | --------------------- |
| Organization dedicated domain | Not supported | Supported         | Supported                | Supported             |

The organization dedicated domain is chosen and configured by the Organization Admin in the YiDA workbench. It represents your organization's identity and brand on YiDA, and helps strengthen your corporate image and brand recognition.

## Basic Concepts

A domain name is a string used on the internet to identify and locate resources such as websites and servers. It is an address made up of a sequence of characters, designed to make websites or servers easy to access and remember. A domain name consists of multiple parts separated by dots (`.`).

* Top-Level Domain (TLD): The last part of a domain name, indicating its category, country, or region. Common TLDs include .com, .org, .net, .gov, .edu, and .cn.
* Second-Level Domain (SLD): The part before the TLD, customized by the registrant. For example, in aliwork.com, aliwork is the second-level domain.
* Subdomain: The part before the second-level domain, used to further organize and structure a website. For example, in xxx.aliwork.com, xxx is the subdomain.

The YiDA organization dedicated domain is a subdomain under the `aliwork.com` second-level domain. You can customize the `xxx` part in `xxx.aliwork.com` as your subdomain.

<Note>
  Keep the following in mind when modifying your organization dedicated domain:

  * Paid editions of YiDA currently allow the custom subdomain to be modified up to three times.
  * The organization domain is shared by all apps within the organization. Once the domain is modified, the access URLs of all apps will change.
  * If you keep using the old domain to access YiDA, you may be prompted to sign in again. After signing in, you will be automatically redirected to the new domain.
  * Any services called from a page using a fixed domain—such as through a Data Source, JS code, or attribute configuration—will stop working. Update them to the new domain or use relative URLs.
  * Links in Chats and To-Do items that have already been sent will not change. Sign in again to access them.
