Advice 1: How to decode ip address

IPaddresses are unique. They have a length of 4 bytes and are written as four groups of numbers from 0 to 255, separated by dots. Each group represents a network, a group of nodes and identifying the node.
How to decode ip address
Look at the first group of digits on the left. It determines the class of an IPaddress. There are only five. They are designated by the first five letters of the Latin alphabet: A, B, C, D, E. They are distinguished by a numeric value. Class A is from 1 to 126, from 128 to 191, C - 192 to 223, D - 224 to 239 and E - 240 to 247. The classes differ in the number of bits of network numbers and host, and this affects the breadth of interval values. Classes A, b and C are used to send information to individual nodes or network linked computers. But such broadcasts are not always needed. When you need to select a group of nodes that are not members of a common network, using a class D. While the range of E is still in reserve.
Eliminate the possibility that a special IP ' mi. These include, for example, those whose first three digits are 127. In this case, the computer receives data from itself, and the data is processed on the source host. Typically, this address is written to test. The opposite is the IP, which sends data to all nodes on the network and is used for limited broadcast. In addition, the service address is, which serves for identity of the node sender.
Find out whether the IP address was local. These include those first two groups of figures which is 192.168. Use them to configure local networks.
Check the IP address on any of the specialized Internet services. Entering the address or domain, you will get maximum of information, to whom and where he belongs. Do it, for example, on the websites, or
Translate IP to domain using special scripts. This check propose to do here - If the IP does not correspond to any domain, the service will not give out any information.
Use the utility "Network calculator" or similar for calculation of IP addresses that are required when configuring network services. Such a lot of offers on different sites - for example, you can use, or

Advice 2 : As recorded ip address of the computer

After making a connection to the Internet or a local network in most cases, the computer needs to assign a unique IP address. For inexperienced user this can be difficult.
The IP address of the computer

What is the IP address

IP address – the unique combination of digits for the recognition of computer on the network. The presence of such ' may be necessary to connect to the Internet and also to interconnect two or more computers.

Provider or network operator, the subscriber is given an individual IP address, called a static. If an individual no address, the IP address is called dynamic and is constantly changing. In this case there is no need to register the address in the connection properties.

How to record IP address

The IP address is recorded in the adapter settings. With him, the mandatory subnet mask.

The sequence of actions to record IP address is.
1) right-Click the mouse over the network sign in the bottom right corner of the screen.
2) Select and open "control Center network and sharing".
3) Click "Change adapter settings" from the left side.
4) Choose the network connection you want to assign an ip address.
5) Click on connection right-click and select "Properties".
6) Select from the list of components the Internet Protocol version 4 (TCP/IPv4)" and open the Properties window.
7) tick "Use the following IP address". In the field "IP address" enter the address in a sequence of numbers separated by periods. In the field "subnet Mask" to fit the standard mask of, if other is not provided by the ISP.

Need network connection you can learn the name of the adapter. If the IP address is required for the ADSL connection or to establish a connection with other household computers, you should choose the connection with the adapter Realtek. If the IP address is assigned to the satellite connection, the adapter can be Virtual MPE Decoder Adapter or TAP 9. If the connection is wireless, the adapter can be either Bluetooth or Wi-fi. The adapter name is written in the connection properties in the "Connect using".

If you want to connect your computer to other computers via LAN, then IP address you can customize. For example, the address of the Central computer in the LAN may look like this: Then other computers on the local network must be set to the addresses,, etc. the subnet Mask must be the same, and as the gateway registers the IP address of the host computer. It should be noted that this address is only used in the local network. To access the Internet in the Central computer must be configured to connect the hotel with its IP address.
