Q1: 如何在Volcengine Network DNS中添加新的DNS记录？

A: 在Volcengine Network DNS中添加新的DNS记录，您需要登录到Volcengine控制台，选择相应的网络服务，然后在DNS管理页面中点击“添加记录”。您需要填写记录类型（如A、CNAME等）、主机记录、记录值（如IP地址或域名）、TTL（生存时间）等信息，并保存设置。

Q2: Volcengine Network DNS支持哪些类型的DNS记录？

A: Volcengine Network DNS支持多种类型的DNS记录，包括A记录（将域名指向IP地址）、CNAME记录（将域名指向另一个域名）、MX记录（指定邮件交换服务器）、TXT记录（存储文本信息）、NS记录（指定域名服务器）等。

Q3: 更新DNS记录后，多久可以在外部生效？

A: 更新DNS记录后，通常需要几分钟到几小时才能在互联网上生效，具体时间取决于DNS服务器的缓存刷新时间（TTL）。默认情况下，Volcengine Network DNS的TTL设置为300秒（5分钟），但您可以根据需要调整。

Q4: 如果我想删除一个DNS记录，应该注意什么？

A: 在删除DNS记录之前，请确保该记录不是必需的，因为删除记录可能会导致服务中断或无法访问。删除记录后，该记录的值将不再指向任何资源，因此请确认您不再需要该记录。删除操作是不可逆的，一旦执行，记录将立即从DNS中移除。

Q5: 如何在Volcengine Network DNS中设置DNS解析优先级？

A: 在Volcengine Network DNS中，您可以通过设置不同的DNS记录和它们的TTL来间接控制解析优先级。通常，您可以将TTL设置得更低的记录（如A记录）放在前面，而将TTL设置得更高的记录（如CNAME记录）放在后面，这样在DNS解析时，更可能优先使用TTL较低的记录。
