有时候翻墙时需要设置国外DNS服务器而不翻墙是使用国内DNS服务器好些，这个软件就可以帮你快速切换，感谢AS网友推荐。

我的 QQ 能聊天，但是什么网页都打不开了，怎么办？！。。。。。。噢 No，我重新登录 QQ 居然都上不去了！
出现这种情况，一般都是 DNS 出问题，今天介绍几款 DNS 测试软件，可以方便的解决这个问题，当然，不限于此。
首先出场的是 彗星 DNS 优化器。 这个软件内置了大量的 DNS 服务器地址，几乎囊括了国内各省市的主要 DNS 服务器地址和国外一些著名的 DNS 服务器地址例如 Google，OpenDNS 等。软件的使用非常简单，启动后使用测试一键优化，软件会测试所有的 DNS 服务器地址速度以及解析质量，最后把软件认为最好的 DNS 服务器自动设置给你的网卡。之后你只需要在运行框中输入 ipconfig /release ，然后再输入 ipconfig /renew 即可让新的 DNS 服务器生效。强烈建议新手用户和走南闯北的售后服务人员，使用这个软件来解决 DNS 相关故障。
第二个是 DNS Jumper 。这个软件也内置了一些 DNS 服务器地址，但是大多是国外的，好在可以通过编辑 ini 文件来添加国内的 DNS 服务器地址。它可以通过点击 Fastest DNS 按钮来批量测试 DNS 服务器，也可以在下拉菜单选中一组 DNS 服务器后点击下面的 check response time 来测试，之后只需点击 Apple DNS 然后 Flush DNS 即可让新的 DNS 服务器生效。
第三个是本站曾经多次提及的 GRC’s DNS Benchmark 。这款软件可以全面测试 DNS 服务器的解析速度，安全程度，专业程度较高，并不建议初级用户使用。
最后一个是 NameBench 。这款软件是比较纯粹的一款 DNS 服务器测速软件，DNS 服务器手动填写，但是软件可以根据自动侦测出来的用户区域来添加区域内最佳 DNS 服务器。内置 Alexa Top2000 为待测试网站地址，生成的报表非常详细，包括速度和劫持情况。测试完成后也会提醒用户哪几个 DNS 服务器最适合当前的测试机器。
你也可以去 dnsentropy 在线测试你当前使用的 DNS 服务器状态。
附件包括了本文介绍的所有软件，均为免安装版本。

本地连接的DNS和路由器DNS配置不同的话，会不会有冲突？
从网上找到的答案，”HOSTS表优先，其次到本地连接指定的DNS解析，如果本地连接DNS设置为路由器IP则路由器会将DNS请求转发给路由器设置的DNS”。设置本地网卡 DNS 地址后域名解析不使用路由器 DNS 设置的。
GRC’s DNS Benchmark比较难用么？我觉得只要把默认的服务器移除，加入要测试的服务器，然后测试就可以了。至于报告会自动把较快的放在前面，这么用对的吧？
我都是直接用谷歌的，哈哈
树大招风吧？
还有个问题，用谷歌的话，解析本地或者说国内的，速度是不是不及本地DNS？记得曾经有人提到过这个问题。
是的。

“ProxyTools is a package of Perl network utilities designed mainly to assist those whose Internet access is censored, unreliable, or otherwise damaged. Uncensored access is provided to any outside service required (Usenet News, Web browsing, IRC, Socks etc.). Setup requires installation of Perl and some modules; this is doable by even a novice MS Windows user with email instruction, allowing help to be provided to those inside these countries from expert users outside. In pursuit of this rather non-specific goal, some interesting network utilities are already produced. We think the code is interesting in itself, useful in other areas, and would welcome contributions to the overall sum of ideas, concepts and ideals expressed in these tools. The project is of interest to the following groups of people: those who live in Internet censoring countries (or corporations, schools, universities) such as the Middle East (United Arab Emirates, Kingdom of Saudi Arabia, Kuwait, Syria), China, Burma, etc. those who would wish to assist those in the group above. those who are interested in Perl code dealing with many aspects of networks at the socket level, and transactions using HTTP proxies. One tool in this project offers a failover capability, and intelligent choice, between various censor-bypassing strategies and network paths, offering the user a robust, uncensored connection even in a low bandwidth, unreliable, packet filtered and proxy-poor environment. those who administer the firewalls which do the censoring, and those who might be considering this. those who are just curious about the current techniques used by the first group above.. A set of tools to analyze network environments, and to aid in avoiding censorship by firewall and proxy blocking”
http://freshmeat.net/projects/proxytools
“Anti-censorship tools (proxyTools) consists of a huge Perl application (localProxy) and a set of tools to analyze the user’s network (proxies, firewall rules, name servers, etc.). LocalProxy abstracts external services in an uncensored, reliable, fast manner to the localhost, where they may be used by standard clients (Web browsers, Usenet news clients, SOCKS-capable clients, etc.). Various combinations of strategies are tried to ensure the non-censored nature of the information, and multiple, parallel services (e.g. HTTP proxies) are used to ensure reliability and speed. The tools are capable of automating collection of the data required for localProxy. LocalProxy builds a configuration for the user and dynamically adjusts to using the fastest strategies and proxies available to it. The tools are useful for network analysis (firewall rules, proxy capabilities, etc.) independently of localProxy. ”
