DNS又名域名系统^{(Domain Name System)}是一个重要的互联网协议。您可以将其视为互联网的通讯录。每当您访问网站时，您的系统都会执行DNS查找。DNS将域名转换为IP 地址^{(IP addresses)}。DNS查找是将IP 地址与其相应域名匹配的过程。请注意，这是对整个过程的简单描述；这不是故事的全部。

默认情况下，您的Windows系统使用您的 Internet 服务提供商 ( ISP )的DNS服务器。^(DNS)您当地的ISP可能没有最快的速度，因此您可能正在寻求改进。好消息是您可以使用其他DNS服务器。这篇文章将向您介绍Google 公共 DNS^{(Google Public DNS)}。

Google 的公共DNS是一项免费的全球域名系统解析服务，可供您使用，而不是您当前的DNS提供商。概述了DNS服务器的工作原理后，值得注意的是，该服务器在您的互联网速度中起着重要作用。

这就是谷歌公共 DNS^{(Google Public DNS)}的用武之地。如果您的网速一直很慢，可能是时候切换到这个快速的DNS服务器了。

How to setup Google Public DNS on your computer

DNS aka Domain Name System is an essential internet protocol. You can look at it as the address book of the internet. Whenever you visit a website, your system performs a DNS lookup. The DNS translates domain names into IP addresses. A DNS lookup is the process of matching IP addresses to their corresponding domain names. Note that this is a simple description of the entire process; it’s not the entire story.

By default, your Windows system uses the DNS server of your internet service provider (ISP). Your local ISP may not have the fastest speeds, and so you may be looking to improve that. The good news is that you can use other DNS servers. This post will introduce you to Google Public DNS.

Google’s public DNS is a free, global domain name system resolution service available for you to use instead of your current DNS provider. Having given an overview of how DNS servers work, it’s worth noting that this server plays a massive role in your internet speed.

This is where Google Public DNS comes in. If you consistently experience slow internet speeds, it may be time to switch to this fast DNS server.
