這是台大的IP吧

你在宿舍嗎

.1不會有人用了吧

你應該住男8吧

Unless you have your local IP address assigned to you, there are only three groups of IP's that are valid for you to use on a machine that's connected to the net (that won't collide with other machines). They are:

10.0.0.0 to 10.255.255.255 (Class A)
172.16.0.0 to 172.31.255.255 (Class B)
192.168.0.0 to 192.168.255.255 (Class C)

So make sure your LOCAL network IP's fall within one of these three ranges, or you're more than likely going to have problems.

1:確定2台os都有灌tcp/ip之netbeui
2:window xp 是不支援tcp/ip的netbeui
3:請將pc-cillin的防火牆關掉
4:請將網路卡的防火牆關掉
5:在ping看看吧
6:在不行我也沒辦法嚕~~

樓上的huang1688說的是正確的,如果你是只用在內部網路,應該設為192.168.1.1與192.16.1.2較為妥當,子網路遮罩都用255.255.255.0即可.
但是如果你的第1台電腦有用固定位址的IP的話(如申請固定位址的ADSL帳戶),這種設定也是行不通的. 你必須將第1台灌上Windows Server,用兩塊網路卡,一個接Internet,一個接內部網路;或使用寬頻分享器了.

我也覺得是(140.112.XXX.XXX 是台大網路的ip)

看他設gateway的ip讓我更以為是(140.112.XXX.254 是gateway)

不過我pm給他,他說他是奇摩撥接帳號分給的ip..........

有點怪

這裡小弟有一個『『大』』疑問？
如果是奇摩撥接帳號，
那怎麼可能給他一組『Class C』的網域？？？

換句話說，
他的整體網域IP都設錯了！

最好請原作者將他目前整個環境的網路環境寫清楚！
要不然大家在此東猜西想的，
問題是解決不了的！

If this IP is assigned to u by ur ISP, then u need 2 NIC in computer 1, and 1 NIC in computer2.

for windows 2000
Computer 1:
1)control panel -> Network and Dial-up Connections -> double click the NIC that connects to the Internet -> properties -> double click 'internet protocol (TCP/IP)' -> select 'obtain an IP address automatically' and 'obtain DNS server address automatically'.

2)control panel -> Network and Dial-up Connections -> double click the NIC that connects to ur LAN -> properties -> double click 'internet protocol (TCP/IP)' -> select use the following address' -> type in 192.168.0.1 for 'IP address' and 255.255.255.0 for 'subnet mask.'

computer 2:
control panel -> Network and Dial-up Connections -> double click the NIC that connects to ur LAN -> properties -> double click 'internet protocol (TCP/IP)' -> select use the following address' -> type in 192.168.0.2 for 'IP address' and 255.255.255.0 for 'subnet mask.'

This should be able to solve ur problem.

btw, if ur ISP doesn't support multiple logon then u would need to download a program and install it in the first computer to share internet connection with other computers. (I'm talking about windows 2000.)

為什麼一定堅持要設定IP位址呢？兩台都不設也可以啊！
