As more and more people use the internet all over the world, many users begin to question the security of their public information. There is a multitude of ways to protect online information such as only visiting trusted websites and making your passwords hard to guess. However, people can still track your internet address and find what you have been doing on the internet. Internet addresses (IP addresses) are given to every device and network that can connect to the internet. They allow for internet sites to know which users are accessing them and where to send information to. Virtual private networks (VPNs) are one way to protect your internet address and privacy.

There are two types of internet protocol addresses (IP address). The first is a private IP address, which is the address that is given by your router at home to its devices such as computers, printers, TVs, and phones. A private address is connected only to your personal router and can only be accessed by your network. Private addresses usually begin with 192.168 and are followed by two more numbers. The other type of IP address is the public IP address. This is used to interact with the internet. An ISP (Internet Service Provider) assigns a public address to every router and can be easily found by typing “What is my IP address” into a Google search engine. Since a public address is needed to do any form of interaction with the internet, people can access and track it. VPNs are one way to protect a public address.

VPNs encrypt data to hide your IP and location. This keeps data secure and private. They do this by creating what is known as a tunnel protocol to transfer data packets and act as a security layer. This is especially important in public hotspots and places where lots of people are using a Wi-Fi network at the same time. Public Wi-Fi networks allow almost anyone to connect, making it vulnerable for anyone to hack. 

VPNs can be used to connect to a private server. Many large corporations use VPNs to allow employees to connect to their work server so that they can access it and do work while on the go or even at home. VPNs can also change your location by connecting to servers in other countries. This allows for users to access blocked sites such as social media or even watch streams that are locked to a specific geographical location. 
   
Software like VNC and Cisco AnyConnect can allow users to connect to other private networks such as work servers. Public VPNs such as ExpressVPN, NordVPN and Private Internet Access can be used by almost anyone to protect their personal internet usage. There are many options available for the general public to use to help protect internet data, so that no matter where you are in the world, you can be safe.
