让上网更快速更安全 OpenDNS上网新方式

让上网更快速更安全 OpenDNS上网新方式 让上网更快速更安全 OpenDNS上网新方式(还能摆脱电信的 DNS 劫持) 无论你何时使用Internet，都会用到DNS。每次发送电子邮件或是在网上冲浪，你都必须依赖DNS。DNS负责主机名字之间和互联网络地址之间的映射，是由计算机来处理的，要是连接DNS服务器的过程出现延迟，或者如果DNS服务器解析某个地址时间过长，那么访问就会出现延迟。而如果能够以某种方式加快域名解析，就能够加快上网冲浪的速度，下面介绍的是一种加速方法:使用OpenDNS。 OpenDNS可以使您对Internet的访问Safer(更安全)，Faster(更快)和Smarter(更聪明)。 所谓更安全，是指OpenDNS可以屏蔽掉一些网络钓鱼(phishing)网站，在您访问这些网站时给出警告。所谓更快，是指OpenDNS提供的DNS查询服务速度比较快，而且使用了高速缓存等技术提高DNS查询速度。 所谓更聪明，是指当你输错一些网址的时候，比如把nba.com错输成nba.cmo，OpenDNS会检测到这个错误，并返回正确nbao.com的IP地址。另外，你还可以设置Shortcut(缩略名)，比如，设置"mail"指向"mail.yahoo.com"，以后当你在地址栏输入"mail"后就会自动访问"mail.yahoo.com"这个地址。 还有，OpenDNS更可靠，它可以保证长期有效，不会让您因为DNS服务器停止工作而无法访问互联网。OpenDNS也使用了分布式网络，在全球架设了服务器，使得每个访问者可以在离自己最近的服务器进行DNS查询 。 OpenDNS服务器分布、 OpenDNS的使用很简单，和其他的DNS服务器一样，只要把网络连接里的两个DNS服务器地址改成OpenDNS的208.67.222.222和208.67.220.220，下面分别介绍以下主要操作provides venture platform, makes many youth round has venture dream, for national solution has important of employment problem.

Currently facing the industry transformation and upgrading, and transform and upgrade traditional industries, is the development of new industries such as tourism, logistics, e-commerce, we still lack a large number of capital operation and management of talents, the lack of technological innovation, technology transfer, product research and development, tourism services and other high-level professional and technical personnel. Especially with theIndustry further develops, the demand is growing. We must stand in the global and strategic height, with a high degree of political responsibility and historical mission, counties implement talent strategies as a major and pressing task to seize good, practical human resource development as industrial counties of the country. Departments at all levels must firmly establish the "talent is wealth, talent is competitive, talent is creativity" concept, fully aware of the extreme importance of talent, the real talent working on the agenda, the primary task of the primary resources to support the development of talent. 2 the construction of enterprisers ' as the starting point, and promote the transformation and 系统的设置。 一、 Windows XP/2000/2003 Windows XP/2000/2003 这三种操作系统基本是相同的，如果使用Windows XP，先选择“控制面板”?“网络和Internet连接” ?“网络连接”，从“网络连接”窗口中鼠标右击网络连接，然后选择“属性”。 往下滚到Internet这一项，选择“属性”。 选择屏幕底部的“使用下面的DNS服务器地址”。对于首选DNS服务器，输入这个地址: 208.67.222.222。对于备用DNS服务器，输入这个地址: 208.67.220.220。点击“确定”，如下图。 在Windows XP中设置Opendns服务器的Ip地址 然后依次点击“关闭”。重新启动计算机，这样设置就会生效。 要检查是否生效可以使用两种方法: 1. 访问主页 如果出现下图界面，那么设置就成功了。 provides venture platform, makes many youth round has venture dream, for national solution has important of employment problem.
