[原创]获得当地 DNS 地址的方法

Modem

[watermark]Modem设置路由时，必须知道当地DNS服务器地址，怎么才能得到呢？自己的方法，不敢独享，特奉献出来，希望对你有所帮助。
当你设置好路由，保存重启后，刷新Modem的WEB界面，查看“系统日志”，其中
1/1/1970 0:20:17> PPP1: DNS Primary IP address is 210.52.107.2
1/1/1970 0:20:17> PPP1: DNS Secondary IP address is 210.53.31.2
就是你所需要的DNS地址了，填入Internet协议（TCP/IP）属性里即可。
我的大亚DB108－B刷成星网数码，设置好路由选项，还不清楚DNS地址时无法上网，系统日志是：
1/1/1970 0:0:15> ADSL connected
1/1/1970 0:0:15> PPP1 PPPoE Session is established.
1/1/1970 0:0:15> PPP PAP Authentication failed
1/1/1970 0:0:15> PPP Invalid Username or Password
1/1/1970 0:0:19> PPP1 Session is down.
1/1/1970 0:0:22> PPP1 PPPoE Session is terminated.
1/1/1970 0:20:17> PPP1 PPPoE Session is established.
1/1/1970 0:20:17> PPP PAP Authentication success
1/1/1970 0:20:17> PPP1: PPP IP address is 220.249.132.120
1/1/1970 0:20:17> PPP1: PPP Gateway IP address is 24.24.24.24
1/1/1970 0:20:17> PPP1: DNS Primary IP address is 210.52.107.2
1/1/1970 0:20:17> PPP1: DNS Secondary IP address is 210.53.31.2
1/1/1970 0:20:17> NAT/NAPT Session Start: interface ppp1, WAN IP is 220.249.132.120
1/1/1970 0:20:17> Initialized Dynamic NAPT.
1/1/1970 0:20:17> No Static Session Information is defined.

6/10/2005 18:18:22> Received time from Time Server 128.138.140.44
当填入正确的首选DNS服务器地址和备用DNS服务器地址（可不填），即可正常上网了，开机就连接好了。系统日志是：
1/1/1970 0:0:0> Ethernet Device 0 Detected
1/1/1970 0:0:0> ATM: Detected
1/1/1970 0:0:0> ATM: Setting up vcc0, VPI=0, VCI=35

不用如此麻烦，把DNS设置为MODEM的IP一样的可以。因为MODEM可以做DNS转发的。

我按照楼上的方法试试了，不管用啊

可以先拨号
用nslookup就可以看到DNS了（2K, XP才能用这个命令）

回3楼：
MODEM处于路由方式时，DNS转发都是打开的。
除非刻意把它关闭。
