About IP Addresses
Every computer, laptop, mobile device and router that connects to the Internet has an IP address. It’s sort of like your house number, except it’s an Internet one and is assigned to you by your Internet service provider (ISP). Without them, we couldn’t use the Web for email, shopping or communicating with people online.
Understanding how your IP address works helps you navigate the web and understand why some websites or networks may not be working as they should. But the complexities of IP addresses don’t just stop with knowing what they are. There are also different types of IP addresses, and each serves a specific purpose. Simplilearn’s guide will break down the important points about this network identifier in simple terms that won’t inundate you with technical language.
Your IP address is the unique identifier that marks your location on the Internet. It provides two crucial functions: it serves as the network interface ID and it tells other devices the name of your network connection. For example, the computer you are using at home has a different IP address than your laptop, which in turn has a different IP address from the smart thermostat that’s connected to your Wi-Fi. Your Internet service provider assigns the IP addresses to your devices and they stay with you as long as you keep your subscription active.
Basic Things to Know About IP Addresses
While you’re online, your ip addresses can be viewed by the Web servers of the sites that you visit, as well as those of social media platforms, Internet forums and chatrooms you interact with. Cybercriminals can also obtain your IP address by hacking into your home network or using a bug in an app on your device.
The IP addresses we use today are the result of years of innovation. The Internet Engineering Task Force, the group that invents and maintains the technology of the Internet, created a new format in the 1980s known as “IP version 4,” which is still widely used today. The new IPv6 format has more room for addresses than the stars in the observable universe, and it is gradually replacing the older one.
There are four kinds of IP addresses: public, private, static and dynamic. The type you have depends on the kind of network you are connecting to, the kind of security you need and whether or not you want to make your address permanent. Static and dynamic IP addresses indicate that the device is configured to connect to a network at all times, while private indicates that the address is only used internally and not shared on the Internet. Public IP addresses are used outside a network, and many sites share them in order to save on server costs and to increase their bandwidth. For this reason, they tend to be less secure. The best way to protect your privacy is by using a VPN service on your devices.
