1、如何ping网关ping 网关 检查计算机是否连通代理服务器或者internet ping ip(自己的) 检查网卡 ping ip (别人的) 检查是否连通内网或者外网 如果网络不通，可以按照以下步骤来诊断网络状况： 1.Ping本机IP 例如本机IP地址为：222.31.191.211。则执行命令Ping 222.31.191.211。如果网卡安装配置没有问题，则应有类似下列显示： C:ping 222.31.191.211 Pinging 222.31.191.211 with 32 bytes of data: Reply from 222.31.191.211: bytes=32 t
2、ime1ms TTL=128 Reply from 222.31.191.211: bytes=32 time1ms TTL=128 Reply from 222.31.191.211: bytes=32 time1ms TTL=128 Reply from 222.31.191.211: bytes=32 time1ms TTL=128 Ping statistics for 222.31.191.211: Packets: Sent = 4, Received = 4, Lost = 0 (0% loss), Approximate round trip times in milli-se
3、conds: Minimum = 0ms, Maximum = 0ms, Average = 0ms 如果在MS-DOS方式下执行此命令显示内容为：Request timed out，则表明网卡安装或配置有问题。将网线断开再次执行此命令，如果显示正常，则说明本机使用的IP地址可能与另一台正在使用的机器IP地址重复了。如果仍然不正常，则表明本机网卡安装或配置有问题，需继续检查相关网络配置。 2.Ping网关IP 假定网关IP为：222.31.191.110，则执行命令“Ping 222.31.191.110”。在MS-DOS方式下执行此命令，如果显示类似以下信息： Pinging 222.31.
4、191.110 with 32 bytes of data: Reply from 222.31.191.110: bytes=32 time1ms TTL=255 Reply from 222.31.191.110: bytes=32 time1ms TTL=255 Reply from 222.31.191.110: bytes=32 time1ms TTL=255 Reply from 222.31.191.110: bytes=32 time1ms TTL=255 Ping statistics for 222.31.191.110: Packets: Sent = 4, Receiv
5、ed = 4, Lost = 0 (0% loss), Approximate round trip times in milli-seconds: Minimum = 0ms, Maximum = 0ms, Average = 0ms 则表明局域网中的网关路由器正在正常运行。反之，则说明网关设置有问题，请检查IP，网关等信息是否设置正确。 3.Ping远程IP 这一命令可以检测本机能否正常访问Internet。比如林大主页的IP地址为：202.204.112.68。在MS-DOS方式下执行命令：“Ping 202.204.112.68”，如果屏幕显示： Pinging 202.204.112
6、.68 with 32 bytes of data: Reply from 202.204.112.68: bytes=32 time1ms TTL=63 Reply from 202.204.112.68: bytes=32 time1ms TTL=63 Reply from 202.204.112.68: bytes=32 time1ms TTL=63 Reply from 202.204.112.68: bytes=32 time1ms TTL=63 Ping statistics for 202.204.112.68: Packets: Sent = 4, Received = 4,
7、Lost = 0 (0% loss), Approximate round trip times in milli-seconds: Minimum = 0ms, Maximum = 0ms, Average = 0ms 则表明运行正常，能够正常接入内部网。反之，则表明网络设置存在问题或IP绑定不正确。 4.Ping DNS IP 这一命令用于检查内部网的DNS是否工作正常，如果您可以正常联网，但是输入域名却无法解析时请尝试该命令“ping 202.204.112.66”，如果显示 Pinging 202.204.112.66 with 32 bytes of data: Reply from
8、 202.204.112.66: bytes=32 time1ms TTL=63 Reply from 202.204.112.66: bytes=32 time1ms TTL=63 Reply from 202.204.112.66: bytes=32 time1ms TTL=63 Reply from 202.204.112.66: bytes=32 time1ms TTL=63 Ping statistics for 202.204.112.66: Packets: Sent = 4, Received = 4, Lost = 0 (0% loss), Approximate round trip times in milli-seconds: Minimum = 0ms, Maximum = 0ms, Average = 0ms 则表明DNS服务器工作正常，如果显示“Request timed out.”请马上联系信息中心。
