最近国家对各种不健康的网站进行整顿，在这个过程中由于各地区的DNS负载明显加重导致部分DNS解析有误，所以我们想到了应该用软件在本地对DNS进行缓存，以便避免地区DNS解析错误导致的网页打不开的问题
As long as there’s an Internet, everyone is going to want to do things faster. Browse the web, ping servers, download files, whatever. Every time you go to a new website, or a website you haven’t been to in a day or so, your computer needs to locate the server again using DNS. Each DNS request can take anywhere from 50 milliseconds, to even a second or more, but most are in the 100 to 200 millisecond range. Want to save a couple hundred milliseconds? Probably not, but what about a couple million or more? That’s what AnalogX FastCache is all about.
AnalogX FastCache is a caching DNS server that runs on your local machine and handles any DNS request that your computer makes, from Internet Explorer to your favorite FTP client. Once a query is made, FastCache will override the normal timeout for the item with one that you specify, so instead of saving a query for a couple of seconds, it can save it for a couple of days. Now every time you ask for it again while it’s in the cache, it gives it to you instantly.
FastCache works on all versions of Windows, from Window 95 to Windows 7 and everything inbetween (including XP, Vista, Win2k, etc).
