在我们寻求更好的方法来加速您的互联网(Internet)并增强您的浏览体验的过程中，本文讨论了优化您的计算机 DNS 服务( optimizing your computer DNS services)，以便您比以往更快地连接。DNS代表域名系统，是一个包含(Domain Name System)Internet上所有域名解析的数据库。
要找出任何域的已解析地址，您可以使用域名系统服务(Domain Name System Service)。在您的DNS(DNS)服务器获取任何URL的解析地址之前需要一点时间。只有在您的DNS服务获取解析后，您的浏览器才能连接到相关网站。您可以阅读有关域名和域名系统(Domain Names and Domain Name Systems)的更多信息。
互联网(Internet)的早期只看到提供DNS服务的(DNS)互联网服务提供商(Internet Service Providers)。正是这些公司为您提供了在您打开相关网站之前查找DNS解析的便利。(DNS)随着对更快和安全DNS的需求出现，许多公司开始提供免费或付费的DNS服务。这些公司拥有专门的服务器，不仅涉及DNS解析，还涉及检查恶意软件和网络钓鱼的URL(URLs)。
OpenDNS、ClearCache 和Comodo等公司为您提供DNS服务，保护您免于重定向到充满恶意软件的网站和网络钓鱼网站。一些DNS服务为您提供了额外的功能，例如网站的家长阻止和网络钓鱼(Phishing)防护。
DNS 基准 – 提高您的互联网(DNS Benchmark – Increase Your Internet)速度
当您获得新的Internet服务时，您的ISP会将您的路由器和/或计算机配置为使用他自己的DNS服务器。尽管它们有效，但它们并不总是最适合您。经过一番研究，您可能会发现其他DNS服务提供商的表现更好。由于有许多可用的DNS服务，因此很难手动检查每一项。这就是DNS Benchmark的用武之地(DNS Benchmark)。Gibson Research的免费工具可以通过两种方式帮助您：
- 检查预先列出的DNS服务，看看哪些是最快的，以及您自己的DNS服务在哪里
- 帮助(Helps)您根据您的地理位置创建自定义DNS服务列表，以便您可以使用最适合您的 DNS 服务。(DNS)
以上两个报告都可以帮助您选择对您来说最快的DNS服务，从而帮助您提高Internet速度。
除了检查您的DNS服务的速度之外，它还会检查您的DNS服务是否可靠，以及它是否可以停止重定向到自定义页面。如果DNS服务不能每次都解析域名，则它是不可靠的。当您输入错误的URL而不是向您显示“页面未找到(Page Not Found)”错误时，某些DNS服务会将您重定向到他们自己的广告加载页面。(DNS)
DNS 基准 – 将您的 DNS 服务(DNS Benchmark – Compare Your DNS Service)与其他服务进行比较(Others)
DNS Benchmark中列出了大约 50 种已知的DNS服务。要运行此测试，请单击Nameservers选项卡，然后单击Run Benchmark。
当您运行此测试时，DNS Benchmark会将您的DNS服务与所有这 50 个DNS服务进行比较，然后向您显示包含以下数据的详细报告：
- (DNS)对您所在位置不可靠的DNS服务
- (DNS)将您重定向到自定义页面的DNS服务
- 如果您的DNS服务器正确列出 - 按速度顺序排列。
- 如果您的所有DNS服务器都在响应
- (DNS)比您的DNS服务更快的DNS服务器
请注意，您的DNS服务是指您当前正在使用的DNS服务。(DNS)要了解您为DNS使用的 IP 地址，请单击Windows 系统托盘中的(Windows System Tray)网络(Network)图标。单击(Click)打开网络和共享中心(Open Networking and Sharing Center)。在出现的窗口中，单击更改网络适配器(Change Network Adaptors)。在出现的对话框中，单击以选择您的网络。右键单击以选择属性(Properties)。在出现的对话框中，单击IPv4并再次单击Properties。您可以在对话框底部看到您当前的主 DNS 和备用DNS 。
以下是DNS Benchmark告诉我我的DNS服务器未正确排序的图像，因此我无法利用最大速度。它还告诉我应该将哪个DNS服务器设为主要服务器，以及应该将哪个 DNS 服务器输入备用 DNS(Alternate DNS)。编号为 1 的应该是我的Primary DNS，编号为 2 的应该是我的Alternate DNS。
DNS 基准 – 创建(DNS Benchmark – Create Custom DNS List Optimized)针对您的位置优化的自定义 DNS 列表
DNS Benchmark的此功能允许您创建最适合您所在位置的DNS服务器列表。(DNS)它检查可用的不同公共DNS服务，并按速度对它们进行排序。如果发现这些DNS服务器有任何故障，它还会用(DNS)红色(Red)和橙色(Orange)标记显示DNS服务器的不同行。它在“结论(Conclusions)”选项卡中告诉您这些红色(Red)和橙色 DNS(Orange DNS)服务器的含义。根据这些排序结果，您可以选择用最快的可用DNS服务替换您当前的 DNS 服务，而不会出现任何问题。
如果您打算在运行测试后更改DNS服务器，请检查这些DNS服务器处理网络钓鱼和恶意软件的能力。您可以使用DNS所有者的名称进行搜索，以了解他们是否提供充分的网络钓鱼保护。就我而言，虽然DNS Benchmark显示Google DNS位于Comodo的顶部，但我更喜欢使用Comodo DNS，因为后者同时提供恶意软件和网络钓鱼防护。
为了使DNS Benchmark正常运行，当您运行测试时，它必须是唯一使用Internet的程序。(Internet)关闭(Close)所有使用Internet的应用程序，然后运行DNS 基准(DNS Benchmark)测试。此工具可在此处(here)(here)获得。
此外，建议您在确定适合您所在位置的最佳DNS服务器之前，在不同时间运行DNS 基准(DNS Benchmark)测试 2-3 次。这将帮助您消除由于DNS(DNS)服务器速度因流量而异而产生的疑虑。

DNS Benchmark: Optimize your Internet Connection for Speed
Іn our quest to find better ways to spеed up your Intеrnеt and to enhance your browsing experiencе, this artіclе talks about optimizing your computer DNS services so that you get connected faster than ever. DNS stands for Domain Name System and is a database that contains resolutions for all the domain names present on the Internet.
To find out resolved addresses of any domain, you use a Domain Name System Service. It takes a little time before your DNS servers fetch resolved address of any URL. Only after your DNS service fetches resolution, your browser can connect to related websites. You can read more about Domain Names and Domain Name Systems.
The early days of the Internet saw only the Internet Service Providers offering DNS services. It was these companies who gave you the facility to lookup DNS resolutions before you could open related websites. As the need for faster and secure DNS arose, many companies started offering free or paid DNS services. Such companies have dedicated servers that involve not only in DNS resolution but also in checking out URLs for malware and phishing.
Companies such as OpenDNS, ClearCache and Comodo provide you DNS services that protect you from redirection to malware-laden sites and phishing websites. Some DNS services give you additional features such as parental blocking of websites and protection from Phishing.
DNS Benchmark – Increase Your Internet Speed
When you get new Internet service, your ISP configures your router and/or computer to use his own DNS servers. Though they work, they are not always optimal for you. Upon a little research, you may find that other DNS service providers are better performing. Since there are many DNS services available, it becomes difficult to check out each one manually. This is where DNS Benchmark comes in. The free tool by Gibson Research helps you in two ways:
- Runs a check of pre-listed DNS services to see which ones are the fastest and where does your own DNS service stand
- Helps you create a custom list of DNS services based on your geographical location so that you can use the best ones available for you.
Both of the above reports help you choose DNS services that are the fastest for you – thereby helping you increase your Internet speed.
Other than checking your DNS service for speed, it also checks to see if your DNS service is reliable and if it can stop redirection to custom pages. A DNS service is unreliable if it is not able to resolve domain names each time. Some DNS services redirect you to their own ad-loaded page when you enter a wrong URL instead of showing you “Page Not Found” error.
DNS Benchmark – Compare Your DNS Service With Others
There are some 50 known DNS services listed in DNS Benchmark. To run this test, click on the Nameservers tab and click Run Benchmark.
When you run this test, DNS Benchmark compares your DNS service with all these 50 DNS services and then, shows you a detailed report with data on:
- DNS services that are not reliable for your location
- DNS services that redirect you to a custom page
- If your DNS servers are listed properly – in order of speed.
- If all of your DNS servers are responding
- DNS servers that are faster than your DNS services
Note that your DNS service refers to the DNS service you are using, currently. To know what IP addresses you are using for DNS, click on Network icon in the Windows System Tray. Click Open Networking and Sharing Center. In the window that appears, click Change Network Adaptors. In the resulting dialog, click to select your network. Right-click to select Properties. In the dialog box that appears, click on IPv4 and again click on Properties. You can see your current primary and alternate DNS towards the bottom of the dialog box.
Following is the image where DNS Benchmark tells me that my DNS servers are not ordered properly and hence, I am not able to utilize maximum speed. It also tells me which DNS server should I make primary and which one should I enter into Alternate DNS. The one numbered 1 should be my Primary DNS and 2 should be my Alternate DNS.
DNS Benchmark – Create Custom DNS List Optimized For Your Location
This feature of DNS Benchmark allows you to create a list of DNS servers that are optimal for your location. It checks out the different public DNS services available and sorts them in order of speed. It also marks the different rows showing the DNS servers with Red and Orange if it finds any faults with those DNS servers. It tells you the meaning of these Red and Orange DNS servers in the Conclusions tab. Based on these sorted results, you can choose to replace your current DNS service with the fastest ones available without any issues.
If you intend to change your DNS servers after running the tests, check those DNS servers for their capability to handle phishing and malware. You may run a search with the DNS owners’ name to know if they offer ample phishing protection. In my case, though DNS Benchmark showed Google DNS on the top of Comodo, I preferred to use Comodo DNS as the latter offers both malware and phishing protection.
For DNS Benchmark to function properly, it is necessary that it is the ONLY program using the Internet when you are running the tests. Close any applications that use the Internet and then run DNS Benchmark tests. This tool is available here.
Moreover, it is advised that you run the DNS Benchmark test two-three times – at different times – before concluding the best DNS servers for your location. This will help you remove the element of doubt that creeps in due to the fact that DNS server speed varies according to traffic.
