itunes改中华电信的DNS地址加速App&Store(iTunes)下载？效果太明显了
AppStore下载App的时候,
是从苹果的下载服务器中获取数据的,
但到底是从苹果哪里的下载服务器中获取数据,
是域名解析的问题,域名解析需要靠DNS,&DNS告诉你是哪里的服务器,&
那你的电脑就会从那里的下载服务器当中获取数据.很可惜的是,&苹果目前暂未在中国大陆架设iTunes下载服务器,
在我们平时下载App的时候,&我们当地的DNS会将域名解析到美国本土的苹果服务器.而中国大陆和美国本土之间的网络互通那是相当的坑爹.. 所以导致下载很慢..但是如果修改中华电信的DNS,
当你下载App的时候,
DNS会将域名解析到苹果架设在台湾地区当地的下载服务器,而大陆和台湾地区之间的网络互通是非常的给力,
所以就完成了加速.
台湾地区中华电信的DNS服务器IP地址是100%稳定的，N年都不会变的。本人在四川，修改之后可以达到我的光纤12M最大带宽。

不仅如此，我在江苏，北京的朋友改了之后也同样表示可以达到最大带宽，加速非常明显。所以感觉在App
Store下载慢的朋友不妨一试。
最后附上中华电信DNS服务器地址：&
&&168.95.1.1
之前有修改HOSTS文件的朋友别忘记清除HOSTS文件内容,
HOSTS文件路径:
系统目录(例:C:\Windows)-&System32&drivers-&etc-&hosts&用记事本打开hosts,
然后清理之前添加的hosts记录.
强烈建议改完之后关闭iTunes, 然后刷新系统DNS缓存,
再重新打开iTunes.帖子尾部有刷新DNS缓存的方法.&
鉴于有些朋友不明白如何操作,
特附上修改方法.Windows

以上网友发言只代表其个人观点，不代表新浪网的观点或立场。智能手机教程子分类Last night we tried to rent an iTunes movie on our newish Apple TV. Instead of starting right away, the Apple TV said it would be 2+ hours before we could start watching. I&#8217;ve got a healthy 15-20Mb/s connection and a clean wire to the Apple TV, so this shouldn&#8217;t be happening.
A little bit of research turned up a surprising fix: Don&#8217;t use Google DNS.
The iTunes Store has thousands of entrances. Everyone using Google DNS is trying to get in through the same door.
Some anecdotal evidence:
This totally makes sense. iTunes&#8217; video content is delivered by Akamai who has distributed massive datastores around the world so those large files originate from nearby servers and spend less time getting switched around the network. Akamai somehow uses our DNS routing to determine our location. If Google DNS or OpenDNS routes everyone to Akamai the same way, then those Akamai nodes and the pipes leading to them get overwhelmed.
Since most people don&#8217;t know what a DNS server is, this problem primarily affects the &#8220;tech-vanguard&#8221; and those fortunate/unfortunate enough to be inside our circles of helpfulness.
I switched to my ISP&#8217;s DNS servers and now HD rentals on Apple TV are ready to watch in 10-20 seconds.
Go figure&#8230;
(I&#8217;d forgotton, but I wrote about a similar iTunes-DNS problem in March 2009: )
