今天为了一个新网站纠结了下选择哪里的空间，很早之前就说过了VPS配置太麻烦，有安全漏洞也不知道什么时候修复，只好回归虚拟空间。

回归之后，又发现需要独立IP，今天一晚上选择下来都是为了IP纠结的，明明都知道ixwebhosting差评如潮，但是居然还是被诱惑了去，148RMB 1年15IP 3免费域名，多吸引人呀，都是浮云啊，低在线率是肯定的，续费的价格虽然不是特别贵，但是也不少，最后实在无聊列了个列表给自己，列出了Godaddy Hostgator Dreamhost 还有IXwebhosting，比较来比较去还是IX“完胜”，殊不知还是被IP给蒙混了头。

看了Dreamhost的关于IP的wiki才感觉如梦初醒，http://wiki.dreamhost.com/Static_IP_Addresses

Why would I want a unique IP?

There really aren’t too many good reasons. If you want browers that don’t support the http 1.1 protocol to be able to visit your site, you’d need a unique IP. Just about every browser released since 1996 supports this protocol, including text browsers (like lynx), webtv, wap devices, obscure browsers, and the big two.

You might need a unique IP if you run some sort of service from your hosting account (not a website) that requires its own ip. Generally to run these sort of things you should be on a higher plan anyway, which include a unique IP if you’d like it for no extra charge.

One good reason, for those to whom it applies, is to have a domain-dedicated SSL certificate that assures users that their browser is really communicating with yourdomain.com (for example), and to avoid generating any browser security warnings. A domain-dedicated SSL certificate requires a unique IP.

Some SEO experts recommend having a unique IP for each site. They explain that web search bots will be able to access a site easier and check it more efficiently. According to search engine statements, it does not matter whether your site has a static or shared IP, the real king is content! However, if you still want to have a unique IP for SEO, no problem, it is your decision after all.

That’s really about it! Those are the only reasons we can think of you’d want one.

我就不翻译了，一般人都能看懂，说得太到位了。

最后想说的是，IP没用，有用的是内容和服务，希望这段文字对正在选择空间的朋友也有帮助。
