How to find out the address of the computer?

Each PC has its own unique identifier in the network. Firstly, this is the MAC address of the network card, and secondly, the IP address. You may need this data, for example, when setting up a connection through a router. In addition, knowing your IP address can be useful for security purposes: some Internet services allow you to track which IP was last logged into your account, and deny access to it from any other addresses. In this article we will explain how to find out the address of a computer in Windows 7.

MAC Address Definition

The MAC address is the unique identification number of the network adapter built into the computer with which it connects to the Internet. Usually, the ISP registers this number in its database when it first connects your PC and then uses the MAC to identify the user. If you want, for example, to connect to your provider via a router or via another computer, you will need to specify the MAC address of the registered PC in the settings, otherwise there will be no access to the network.

We have already talked about how to find out the MAC address of a computer, in the articles How to find out the MAC address and How to find out the computer ID. In Windows 7, you can do this using the special ipconfig command. Open the "Start" menu, select "All Programs> System Tools" and click on the "Command Line" link in it.

In the command window that opens, type ipconfig / all and press [Enter]. You will see detailed information about the network configuration of your computer. Find the line “Physical address” in it - this is the PC's MAC address. It consists of six pairs of characters separated by hyphens.

Determination of IP-address

The IP address is used to identify the computer on the network. It is very easy to figure out the external IP address of your PC - there are a lot of online services that allow you to do this. It is enough to enter the query “learn IP” in any search engine and select any link you like - for example,.

An external IP address is issued to your computer by an Internet provider. It should be noted that the majority of providers in order to save their subscribers allocatesIP addresscalled "gray" addresses - one IP can correspond to several computers at once and often changes. This creates problems when using a variety of network services.identifying users by IP: for example, some file sharing services allow no more than one connection from one address, and if you are not lucky enough to visit such a site along with one of your “colleagues” by IP, you will not be able to download. Therefore, if possible, you should order a white IP address from the provider for an additional fee.

If your computer is connected to the network via a router, then in addition to the external IP address, under which it is “visible” from the Internet, it has an internal address available on the local network. You can find it out using the same ipconfig command, in this case, even without the / all parameter.

Open a command prompt, type ipconfig and press [Enter]. The address you need is listed in the “IPv4-address” line and consists of four groups of numbers separated by dots. howipconfigtypically, internal IP addresses begin at 192.

Note that in the information about the network connection, you can also see the IPv6 address, but today this information is not very relevant. IPv6 has not yet found a massive use, is rarely used and is not supported by most Russian providers, so you can ignore it.Today, when it comes to IP addresses, it is IPv4 addresses that are meant.

How to learn MAC and IP without command line

You can find out your IP and MAC addresses in Windows 7 without using the command line. To do this, right-click on the network connection icon in the system tray (next to the clock) and select "Network and Sharing Center". In the window that opens, click the "Ethernet" link.IPv4 address

Another “Status - Ethernet” window will appear. Click on the "Details" button. A network connection details window will open containing all the basic information. There is both a physical address (i.e. a MAC) and an IPv4 address. However, it should be borne in mind that if your computer is connected to the Internet through a router, then this window displays information that is relevant only for the local network - the internal IP address and MAC address of this particular computer. The MAC registered by your provider in this case is specified in the settings of the router, and you can find out the external IP using the above mentioned network services.
