On all computer equipment, the interface connected to the Internet network needs an IP address. The latter is a unique number that identifies any equipment connected to a network using Internet Protocol. Its importance in the world of the web is indisputable. In this article, find out everything you need to know about the IP address.
What is the role of the IP address?
The role of the IP address is to transport information from one device to another. In other words, this number allows the devices to communicate with each other. It indeed maps the internet in order to be able to send data to the right address. For example, if a device wants to transmit data from a sender to a recipient, its router looks for the IP header and checks that the source IP matches the target IP very well. If these are in the same network, then the data transfer is easy. Thus, without it, you will no longer be able to browse the web, receive or send emails, or go to Facebook or Instagram.
In addition, the IP address can provide important information such as your exact location, or whether or not you are using a virtual private network. In addition, computer experts claim that this protocol can be used to block or allow access of computer hardware to certain resources. Currently, the IP address exists in two versions, namely:
- the Ipv4 protocol: developed since 1983, today it faces a shortage of addresses. This protocol consists of a series of 4 numbers which are separated by single dots. It can look like this: 18.104.22.168;
- IPv6 protocol: this protocol offers more possibilities than IPv4. Indeed, it allows to create many more addresses than version 4. It was developed to respond to the shortage of IP addresses. It consists of eight numbers which are separated by a colon. It might look like this: 2001: 0db9: 3c4d: 0051: 0000: d432: 4eee: 0000.
How to find your IP?
In some situations, you may be asked to provide your IP address in order to make connections. For exemple, my ip may be essential for remote control or to establish a connection to a game server. In addition, you may also need this number to locate your computer or a mobile device. In other cases, you may want to obtain Internet Protocol information from a third party.
For this, you can use a website specializing in displaying the IP address. This kind of platform will accurately provide you with your IP. It can also show you its exact geolocation on the world map.
Who takes care of the allocation of IP addresses?
IP addresses are distributed by theInternet Assigned Numbers Authority (IANA). The latter is a division of the Internet Corporation for Assigned Names and Numbers (ICANN). This authority has full control over the entire IP address space. At the regional level, it delegates the management of addressing resources to the Regional Internet Registries (RIR). These registries, in turn, assign IP addresses to local provider organizations. These are the ones who are responsible for transmitting them to customers.
