Details
This document details the changes implemented in QTS versions regarding the configuration of Domain Name System (DNS) servers for QNAP NAS devices.
QTS 4.3.4 and earlier
Prior to QTS 4.3.5, NAS devices utilized a centralized configuration for DNS servers. This configuration applied to all network interfaces on the device.
QTS 4.3.5 and later
- Deprecation of global DNS settings: The centralized approach to DNS server configuration has been deprecated.
- Per-NIC (Network Interface Card) DNS management: DNS server settings are now managed independently for each NIC. This enables the assignment of specific DNS servers to individual network connections on the NAS.
- Automatic migration of existing settings: If a NAS was previously configured with fixed DNS settings before upgrading to QTS 4.3.5 or later, the system automatically migrates the first two active DNS entries from the global settings to each active NIC.
Post-Migration Considerations
Following the NAS firmware update, it is recommended that you review the DNS server configuration for each NIC. This verification ensures the settings align with your desired network configuration. To access and modify DNS settings in QTS, see Configuring DNS server settings in the QTS User Guide.

本文档详细说明了在QTS版本中对QNAP NAS设备的域名系统（DNS）服务器配置所做的更改。
QTS 4.3.4及更早版本
在QTS 4.3.5之前，NAS设备使用集中配置的DNS服务器设置。此配置适用于设备上的所有网络接口。
QTS 4.3.5及更高版本
- 弃用全局DNS设置：集中式DNS服务器配置方法已被弃用。
- 每个NIC（网络接口卡）的DNS管理：现在DNS服务器设置独立管理每个NIC。这使得可以为NAS上的各个网络连接分配特定的DNS服务器。
- 现有设置的自动迁移：如果NAS在升级到QTS 4.3.5或更高版本之前已配置了固定的DNS设置，系统会自动将全局设置中的前两个活动DNS条目迁移到每个活动NIC。
迁移后的注意事项
在NAS固件更新之后，建议您检查每个NIC的DNS服务器配置。此验证确保设置与您期望的网络配置一致。要访问和修改QTS中的DNS设置，请参阅QTS用户指南中的
