DNS批量更新是通过单次操作同时修改多个域名或区域的[[dns|DNS]]记录,而不是逐一编辑各个域名。对于大型域名组合,在进行主机迁移、品牌更新或IP地址变更时,需要一次性将新记录值传播到数十乃至数百个区域,此功能至关重要。注册商和DNS提供商通过[[domain-dashboard|域名控制面板]]、CSV导入工具或[[api-domain-management|管理API]]提供批量更新功能。批量更新存在风险——大规模错误可能导致多个网站同时中断——因此变更预览和回滚选项是必不可少的安全保障措施。
示例
After migrating your web hosting, you use a bulk DNS update to point 80 domains' A records from the old server IP to the new one in a single CSV import rather than editing each zone manually.
