1.Internet

  • [1] DNS and how it works?
DNS代表域名系统。它是一个用于将域名(例如example.com)转换为计算机可以理解的IP地址的系统。

当您在Web浏览器中键入网站地址,例如www.example.com时,您计算机上的DNS解析程序会向DNS服务器发送请求,
请求与该域名关联的IP地址。然后,DNS服务器使用托管网站的服务器的IP地址响应。

DNS系统的工作方式类似于分布式数据库,全球范围内有数百万个DNS服务器。当DNS服务器收到域名请求时,
它首先检查自己的缓存是否已经具有该域名的IP地址。如果没有,它会查询其他DNS服务器,直到找到正确的IP地址。

DNS还支持不同类型的记录,包括A记录(将域名映射到IP地址)、MX记录(指定域的邮件服务器)和
CNAME记录(允许一个域名是另一个域名的别名)。

总体而言,DNS通过提供一种将人可读的域名转换为计算机可读的IP地址的方式,发挥着使互联网正常运行的关键作用。
