网络 IP 绑定问题

尝试绑定 /29（我的，不是 ISP 或数据中心的）。它在我的核心交换机上路由良好。

interface Vlan70
description SERVER070
ip address xxx.xxx.42.45 255.255.255.248

/etc/sysconfig/network-scripts/ifcfg-eth0-range0 的内容

IPADDR_START=xxx.xxx.42.47
IPADDR_END=xxx.xxx.42.50
CLONENUM_START=1

/etc/sysconfig/network-scripts/ifcfg-eth0 的内容

DEVICE=eth0

我正在运行 Centos 6.5 64 位，是的，我已运行服务网络重启且没有错误。出于某种奇怪的原因，我无法 ping 通 IP，也无法正确绑定它们。

nc: connect to www.google.com port 80 (tcp) failed: Connection timed out
