DNS传播检查程序

Whats My DNS是专为检查DNS解析给定的域而设计的。它对那些最近更改了他们的域名服务器或DNS记录的人特别有用。它通过全球各地查询输入域的DNS记录,并显示一个域的IPv4和IPv6地址,这有助于识别更新的DNS记录还在全球传播。

为什么我的DNS还没有传播?

世界各地的isp都有不同的缓存级别。DNS客户端或服务器可能会将DNS记录的信息缓存到其DNS缓存中。这些信息被临时缓存,当TTL(生存时间)到期时,DNS服务器将获取更新的DNS信息。

什么是DNS解析?

DNS解析是主机名到IP地址的转换。而DNS解析器是DNS查找过程中的第一站。它负责处理发出初始请求的客户端。DNS解析器启动一系列查询,最终将URL或主机名转换为所需的IP地址。

传播能加快吗?

没有什么可以加速DNS传播过程。通常,名称服务器更改最多需要48到72小时才能完全传播。然而,DNS区域记录的变化,如A、MX和CNAME记录通常需要0到4个小时才能解析,但最多需要8个小时才能传播完整。
