Advice 1: How to find the ISP gateway

Connecting the local computer to the Internet, usually with the help of intermediate router, the company providing the service connection. When using TCP/IP Protocol this device is called the main gateway. Sometimes you need to find out IP address of the default gateway of your Internetprovider.
How to find the ISP gateway
There are several ways to do it. For example, you can see this IP address in the window properties of the network card of the computer to the network. To reach it open the main menu on the "start" button and in the section "settings" click on the line "Network connections". Open the folder with shortcuts of all established connections, among which you need to find your current and click the right mouse button. In the popup context menu, click "Status" to open the window with information about the connection. It has two tabs - you need the one that says "Support". IP address of the default gateway of this connection placed in the bottom row on this tab.
Another way is to use the ipconfig utility from the set of standard operating system. For this you need to run a terminal command prompt. In the main OS menu there is a line "Run" - click it. This way you will open the dialog box run programs. It is possible to do by pressing hotkeys WIN + R. In the input box type cmd and click OK (or press Enter). So you run the terminal window in which you need to type ipconfig and press Enter. Starts a utility that determines and displays in the terminal window settings for all existing connections of the computer. Will this list and IP address of the default gateway.
However, it is necessary to take into account the fact that when you connect to the Internet not directly but through the router, the main gateway for your computer will be the router. Respectively, obtained by the method described above the IP address will be the IP address for the internal network. To overcome this obstacle it is necessary to connect a cable Internet connection to a network card in your computer directly, or just contact support at your provider with a question about the gateway address.

Advice 2 : How to find network address

The network address (also called MAC address of a computer) can learn a few common ways. The easiest, of course, to know the network address of the computer, looking at the label or packaging of the network card. In the case where we are dealing not with a computer but with a laptop, you need to pay attention to the bottom of the device — there should be a sticker that lists the MAC address of all network interfaces. If there is no sticker on the bottom of the laptop it should be on the packaging. But what if the packaging or documentation for the network card is not preserved?
How to find network address

You can use the command ipconfig. To do this, go to "start menu" and choose "Run", typing in the field cmd. The console window appears black, it should type the command ipconfig/all. After that, the on-screen text looking for "local area Connection" (Ethernet adapter). The string "Physical address" and will represent the desired MAC address. If one computer has multiple network cards, the physical addresses in the list respectively, will also be several, one for each installed card. It is therefore necessary to select from the list the address of the card, which you are currently interested in.

There is another way of determining the network address of the computer that are considered the most effective, but at the same time very popular and commonplace. He is to use two commands - ping and arp. In this case, it first performs a ping target, and then the arp–a command. After executing this command, you will see a table. It will contain the MAC address of the adapter that you are interested in. This method is most commonly used in a conventional peer-to-peer network. The fact is that if the network is segmented and uses the routers to find the MAC address of the computer to learn will not work (will only know the network address of the router).
