公司有2台服务器A(218.34.45.65)与B(218.34.45.66)。都放在托管服务器那边！
已知A的服务器配置：
IP：218.34.45.65
子网掩码：255.255.255.66
默认网关：218.34.45.10
DNS1:123.34.35.45
DNS2:123.34.35.1
现在要根据服务器A配置，来重新配置服务器B的静态IP，以便于外网访问这个服务器
B服务器的版本是centos 5.7
IP：218.34.45.66 //只更改了这个地方
子网掩码：255.255.255.66
默认网关：218.34.45.10
DNS1:123.34.35.45
DNS2:123.34.35.1
问题：
1.修改后发现B服务器能PING通A服务器，却PING不用外网，是什么原因？跟防火墙有没有关系？
2.子网掩码一般看到的都是255.255.255.0，为什么这边会是255.255.255.66
3.子网掩码，默认网关，DNS是不是都是托管服务器提供
4.从上面配置上看，是不是这些网线是直接接入服务器，而没有通过路由器的，因为我理解的通常做法都是使用内部IP（如192.168.0.10），然后通过路由器映射出去，让外部可以通过静态IP访问这个192.168.0.10的服务器
回复讨论(解决方案)
你给的是路由器通道地址，而非主机ip
同个机房不等于同个路由接入，具体的你还需要询问机房的IP分配才对，不要自己乱设置。
哈哈，这个你不是解决了！也不结贴！
