The provider automatically assigns a connection ID to each client when connecting to the Internet. Without such ID, no user can get to the Internet, go to the search engines, or in his private office at the provider. Internet Protocol (IP), which combines computers and servers into a single global network, starting with small subnets of a private provider to global Internet. It's a sort of spider web.
Divided IP (IP) on the gray and white. This is not an official and slang separation – the color doesn't matter, it just happened. Gray IP addresses are called local IP addresses and internal IP addresses, in fact, are synonymous. Accordingly, if you hear "Internet IP address", "external IP address" or "real IP address" - this is synonymous to white IP address.
If you want to check what the ip issued by the ISP when you connect to the Internet, do the following. Click the "start" button, choose "Run..." in the input field write "cmd". This command is called command line OS Windows having a black window where you need to enter the command “inconfig”. Thus, it displays the network settings for Internet.
If the string of IP address that starts with 10.0.0.0, 172.16.0.0, 192.168.0.0 – such IP grey, others are white. But if Internet access is implemented through a router (the router), then your computer is on a local LAN. Such a network allows simultaneous Internet access up to 256 computers, although usually limited to from one to five home computers or phones.
To find out the real IP address when you access the Internet through a router, you need to visit one of the sites 2ip.ru or internet.yandex.ru. At first site the real IP address issued by the ISP will be after the lines "Your IP:". The second IP address appears in the string "My IP:".
Check the "color" of IP is possible only with a working Internet connection.
Advice 2 : How to find your ip type
Each network computer is assigned an IP address. It is a unique network identifier, the network at a time can not be two computers with the same address. And addresses can be static or dynamic. Sometimes the user may need to know the type of the used IP addresses.
What distinguishes a static IP address from dynamic? The fact that the first never changes, while the second changes with each new connection. The type of IP address is determined by the provider and largely depends on your connection method. Wired Internet it is usually (but not always) static – that is, assigned once and does not change even if you shut down the computer.
In that case, if you use a USB modem, the IP address is dynamic. When you connect you are assigned a free address from owned provider of a range, with the logs of the server through which you connect provides information about who and at what time was assigned to this IP address. If you are using a USB modem there is the possibility, for a fee, to obtain a permanent address.
To determine your IP addresses go to one of the services providing similar services, for example, on the website http://www.ip-1.ru/ At the top of the page you will see your current network address. Write it down, then disconnect from the Internet and wait a few minutes. Then connect again to the Internet, log on to the above services and check the same recording. If it is the same, it means that your IP address static. If the record has changed, something dynamic.
Are there advantages of static or dynamic addresses? Static address need someone who is on your computer open resources – for example, set your ftp server. If you are a site administrator, then the static address allows you to configure entry to the resource to bind to an IP address, which greatly increases safety.
The disadvantage of static IP addresses that an attacker, knowing it can methodically pick "pick" to your computer. Since the IP address never changes, he has nearly unlimited time to crack. In this respect much more safe is the dynamic address changing with each new connection.
