Any computer or device that connects to the internet has a unique identifying number, called an Internet Protocol address or IP address for short. This address is allows computers to find one – another and communicate across the network.
IP address meaning:
A UNIQUE STRING OF NUMBERS SEPARATED BY FULL STOPS THAT IDENTIFIES EACH COMPUTER USING THE INTERNET PROTOCOL TO COMMUNICATE OVER A NETWORK.
An IP address is a interesting product of modern computer technology designed to allow one computer (or other digital devices) to communicate with another over a network. IP addresses allow the location of truly billions of digital devices that are connected to the Internet to be pinpointed and differentiated from other digital devices. In the same sense that someone needs your mailing address to send you a letter, a remote computer needs your IP address to communicate with your computer.
What is IP (Internet Protocol)
“IP” stands for Internet Protocol, so an IP address is an Internet Protocol address. What does that mean? An Internet Protocol is a set of rules that govern Internet activity and facilitate completion of a variety of actions on the World Wide Web. Therefore an Internet Protocol address is part of the systematically laid out interconnected grid that governs online communication by identifying both initiating devices and various Internet destinations, thereby making two-way communication possible.
How IP addresses work
An IP address consists of four numbers, each of which contains one to three digits, with a single dot (.) separating each number or set of digits. Each of the four numbers can range from 0 to 255. Here’s an example of what an IP address might look like: 126.96.36.199. This innocuous-looking group of four numbers is the key that empowers you and me to send and retrieve data over our Internet connections, ensuring that our messages, as well as our requests for data and the data we’ve requested, will reach their correct Internet destinations. Without this numeric protocol, sending and receiving data over the World Wide Web would be impossible.
Type of IP addresses
IP addresses can be divided either static or dynamic. Static IP addresses never change once they are assigned to a device on a network. They serve as a permanent Internet address and provide a simple and reliable way for remote computers to contact you. Static IP addresses reveal such information as the continent, country, region, and city in which a computer is located; the ISP (Internet Service Provider) that services that particular computer; and such technical information as the precise latitude and longitude of the country, as well as the locale, of the computer. Many websites provide IP address look-up services to their visitors, free of charge. If you’re curious about your own IP address, you can locate by performing a Google search.
Dynamic IP addresses
These are temporary and are assigned each time a computer accesses the Internet. They are, in effect, borrowed from a pool of IP addresses that are shared among various computers. Since a limited number of static IP addresses are available, many ISPs reserve a portion of their assigned addresses for sharing among their subscribers in this way. This lowers costs and allows them to service far more subscribers than they otherwise could.
Static IP addresses
These are generally preferable for such uses as VOIP (Voice over Internet Protocol), online gaming, or any other purpose where users need to make it easy for other computers to locate and connect to them. Easy access can also be facilitated when using a dynamic IP address through the use of a dynamic DNS service, which enables other computers to find you even though you may be using a temporary, one-time IP address. This often entails an extra charge, however, so check with your ISP.
Which is better, Static or Dynamic?
Static IP addresses are considered somewhat less secure than dynamic IP addresses, since they are easier to track for data mining purposes. However, following safe Internet practices can help mitigate this potential problem and keep your computer secure no matter what type of IP address you use.
