Answer 2

I read these answers and only one was correct. Just so you have a second opinion on which one is correct and which ones to ignore, here is the correct answer again:

Click START-RUN, then type in cmd (no qotation marks, this was the only mistake the answerer made).

A black Command Prompt window will open which is what CMD stands for. There are other methods of opening a command prompt window: Go to Start-All Programs-Accessories- in the new list choose "command prompt". It will open just as using the "run" applet will open the command prompt. Just so you know there is other ways of doing just about everything on Windows XP all versions.

At the curser type in------ipconfig/all but without the dashes I just placed in front, so you are not confused.

Now, a lot of information will be displayed on the black screen in white letters. Look down this list and you will see each item is clearly labeled before the entry which corresponds to that entry. Depending on how many cards you have installed you will have one or more entried which relate to each card or adapter. An Ethernet Card IS a Network Adapter, just a wired one. K?

Depending on which is activated as your main means of network connectivity all the connection types will be listed, with the active connection first. So, if you have a wireless connection it would go something like this:

The manufacturer of your network card with the adapter name following directly under it. like this:

Ethernet Adapter Wireless Network Connection:

Connection--Specific DNS Suffix: Belkin
Description: Belkin Wireless Pre-N Notebook Network Card
Physical address: 00-15-75-92-C5-9F (MAC Address)
DHCP enabled: either Yes or No (one or the other, usually yes)
Autoconfiguaration enabled: Yes or No (sao) usually Yes
IP Address: something like 192.168.1.x (replace x with number
between 2-255)
That last entry is the IP Address you are looking for.

Subnet Mask: 255.255.255.0 (This is common Subnet Mask)
Default Gateway: 192.168.1.1 (Router Configuration IP Adress)
Note: your physical IP address MUST be in the same range as your routers or residential gateway address. So if it starts with 192 and so does your nodes (computer or other network device) then you are going to be able to make a connection with the internet. If it is different than the residential gateway like 168 instead you would have to go in and manually configure your IP Adress and that is a huge hassle, trust me.

DHCP Server: Same as Default Gateway Address
DNS Server: Same as Default Gateway address/DHCP Address
Lease Obtained: Usually todays date or the date you connected last and did not disconnect from the net, like it was placed into "sleep mode". Each IP Address behind a wireless or wired router usually stays the same. It is the Routers IP Address and also the method of accessing the browser configuration tool for the Router. Just type in the Routers IP Address into the browser and hit Enter and you are into the configuration pages. You would want to set a password after initial config due to security risks. You would not like just anybody accessing your config pages now would you? Don't set the user name and password until AFTER you have finished all the configuration of both the Router and the Adapter(s). Each Computer must have its own Adapter in order to access the internet without using Internet Sharing through a Server Computer which could be any computer on the network but it must be turned on for the Client computers to access the net. The Client computers are all the other computers on the network which shares the connection. No Fun At All!!! ;-)

Last but not least is this last entry for this Network Card/Adapter:

Lease Expires: Some time in the way future, like 1075!!

If you have more than one Network Card installed on your computer there will be a different listing like above for each one except the FireWire one even though the FireWire will show up on the Network Setup Wizard as an "unplugged" network.

Something like this:

Ethernet Adapter Local Area Connection
Media State: State Disconnected
Discription: Intel(R) Pro/100 VE Network connection
Physical Address: 00-17-27-F2-B4-D3

The disconnected or unused Adapter cards have much shorter content as they do not have any of the above configurations due to the fact they are not in use. If this one, which is my Wired Ethernet Card were in use instead of my Wireless Ethernet Card, then it would have all the information listed under it that my Wireless Ethernet Network Card Connection has listed. The IP Address, Physical Address, if DHCP is enabled the Subnet Mask and the DNS Server information, or whatever information corresponds to that particular form of network connection.

Answer 3

go to command prompt
and type "ipconfig / all"
result is your IP,subnet mask,physical address , default getway.......
subnet mask is similar IP but those number is for your computer to know the receiver pc is in our network or not
and defult getway is usually a router or an ISP or server in network that handle network traffic for more information :>
