几个提供在线ping的URL

在使用虚拟主机或者租用主机又或者主机托管，由于物理距离上的限制，无法知道网站的访客访问的速度如何。这时候需要借助别的一些提供在线ping服务的网站。

下面列举一些：

1. http://ping.eu

提供了

Domain or host name:

Port number:

Ping	Traceroute	DNS lookup
WHOIS	Port check	Reverse lookup
Proxy checker	Mail relaying	Bandwidth meter

等服务。

2. http://network-tools.com/

提供了和ping.eu类似的服务：

3. http://just-ping.com

just ping的服务就跟名字一样了，只提供ping服务，不过ping的结果比较全，是来自世界各地的。
