更改DNS吧,感受真实的网速~

OpenDNS makes the Internet experience safer, faster and smarter for you and everyone using your network.

1. OpenDNS is safer

OpenDNS can identify and stop sites trying to phish (steal) your personal information or money. The OpenDNS phishing protection works with all operating systems and browsers, and complements any other security measures already in use, such as a firewall and anti-virus software.
OpenDNS可以识别和阻止钓鱼（Phishing）网站，就像在你访问的网站和你之间设了一个检查站，保护你的安全。

Here's what a blocked phishing site looks like for OpenDNS customers:

2. OpenDNS is faster

Most DNS servers on the Internet are slow. Your computer uses DNS every time you visit a website or send an email, so you want DNS to be blazing fast. Two things make DNS really fast: a big cache and a good network. We have both.

Not to brag, but OpenDNS caches are really big.

The bigger and better the cache, the fewer steps in the process, and the faster the Internet experience. Making the OpenDNS caches really big is part of how OpenDNS makes the Internet faster.
两个特点保证了OpenDNS更快，首先它拥有一个大型的、智能化的缓存，这能够保证用户可以从庞大的OpenDNS用户库中获利；OpenDNS有一个高性能的按地理分布的网络和多个冗余备份连接，它会根据你的访问选择最近的地理位置。

We're in your neighborhood, too.

Speed really matters. You make hundreds of DNS queries a day and every delay adds up. We built our network of OpenDNS caches at the major intersections of the Internet. This keeps us close to you, improving performance. (Interested in peering?)

3. OpenDNS is smarter

We all make speling mistakes.

We make corrections for common spelling mistakes, on the fly. That means when you are typing fast and type yahoo.cmo instead of yahoo.com you still get there. No annoying pop-ups or evil spyware installed because you made a typo. Things just work.

OpenDNS可以自动纠正拼写错误，如果你不小心输入网址时拼写错误（比如少了个字母），OpenDNS也能将你引导到正确的网站，或者提供一个相似网站的搜索列表。

We're not perfect (yet) so when we can't fix your typo we take you to a page with a set of search results.

所以有兴趣的朋友可以试用一下Opendns ,也说说感觉如何, 只要把网络连接属性(TCP/IP协议属性页)中的主要DNS和次要DNS分别改成:

·208.67.222.222

·208.67.220.220

然后检验一下设置成功没
