When I execute an ipconfig command on the Command Prompt in my Windows 98SE system it gives the details as follows:

0 Ethernet Adapter:
IP address: xx.xx.xx.xx (x stands for the IP addresss numbers)
Subnet Mask: 255.0.0.0
Default Gateway: xx.xx.xx.xx (same as IP Address)

1 Ethernet Adapter:
IP Address: 0.0.0.0
Subnet Mask: 0.0.0.0
Default Gateway:

2 Ethernet adapter:
IP Address: yy.yy.yy.yy
Subnet Mask: 255.255.0.0
Default Gateway:

My questions are as follows:
1) I have only one LAN card in the system then what are the other Adapter informations about? (0 Ethernet Adapter, 1 Ethernet Adapter, 2 Ethernet Adapter)

2) Which IP is the IP of my PC?

au revoir
Rahul

Without knowing exactly what the values are, I can't say which is the "right" one and I don't have a Windows 98 system to compare to. However, if one of the addresses is "127.0.0.1", then that is a "loop-back" address. "127.0.0.1" is the standard IP address for referring to your own computer. That is, messages sent to that address don't actually go out over the network.

The one with an address of 0.0.0.0 might be a PPP interface (modem).

I think if you type "ipconfig /all" instead of just "ipconfig" it will display more information about what the interface is.

Hi,

If you use a switch then you will get more information. For instance using the -All switch will give you the Netword adapapter name as well as the Physical (MAC) Address.

C:\>ipconfig -all
