+## 域名结构说明
+
+![](https://picture.texous.cn/blog/20250213101552038.png)
+
+## 域名划分
+
+> 二级域名用来区分服务级别  
+> 三级域名用来做服务划分  
+> 四级域名用来做环境划分
+
+### 二级域名
+
+| 域名         | 说明     |
+|------------|--------|
+| qifu.com   | 内网使用   |
+| keyfil.com | 外网访问使用 |
+
+### 三级域名
+
+#### 三级域名说明
+
+- 三级域名 `xxx.qifu.com`：服务划分
+    - 比如 `yapi.qifu.com` 表示接口文档服务
+    - 比如 `confluence.qifu.com` 表示知识库服务
+
+#### 三级域名列表
+
+| 域名                | 服务        | 访问链接                     | 说明    |
+|-------------------|-----------|--------------------------|-------|
+| keycloak.qifu.com | IAM认证授权中心 | http://keycloak.qifu.com | 域账户中心 |
+
+### 四级域名
+
+#### 四级域名说明
+
+- 四级域名 `xxx.jenkins.qifu.com`：服务环境划分
+    - 划分为四个环境：开发 `dev`、测试 `test`、预发布 `uat`、生产 `prod`。生产环境默认缺省，使用三级域名
+    - 比如 `test.jenkins.qifu.com` 表示测试环境 jenkins
+    - 比如 `jenkins.qifu.com` 表示生产环境 jenkins
+
+#### 四级域名列表
+
+| 域名 | 服务 | 访问链接 | 说明 |
+|----|----|------|----|
