What Is An IP Address?



The term IP address stands for Internet Protocol Address. An IP Address is a fascinating product of the modern computer technology designed to allow one computer to communicate with another via the internet. Other digital devices that have the capacity to access internet do also use Internet Protocol addresses to communicate with other devices as well as computers. It allows the location of billions of digital services that are connected to the internet to be pinpointed and differentiated from other devices e.g. if someone needs your mailing address to send you a letter, a remote computer needs your Internet Protocol address to communicate with your computer. They usually consist 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 or set of digits can range from 0 to 255 and might look like 78.125.0.209.


An internet protocol is a set of rules that govern internet activity and facilitate the completion of a variety of actions on the World Wide Web (www). 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. There are two types of IP addresses:


Static IP Addresses


This type of address doesn't change. They serve as permanent Internet Addresses and provide a simple and reliable way for remote computers to contact you. They address and 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 such as the precise latitude and longitude the country as well as the locale of the computer. Static adresses 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 the computers to locate and connect to them. They are considered somewhat less secure 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 and secure no matter what type of IP address you use.


Dynamic IP Addresses


These are temporary addresses and are assigned each time a computer accesses the Internet. They are borrowed from a pool of IP Addresses that are shared among various computers. Since a limited number of static addresses are available, many ISP's reserve a portion of their assigned addresses for sharing among their subscribers in this way. This lowers cost and allows them to service far more subscribers than they otherwise could. Easy access can also be facilitated using 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. In this case it's always advisable to check with your ISP as this often entails an extra charge.
