Pair that IP masking with encryption, and your online activities are kept fully private from ISPs, hackers, and government surveillance. Some VPNs cluster multiple users under one shared IP address, which further anonymizes your internet activity. This prevents anyone from finding your IP address. Based on your IP address, you can see only the content that’s available to viewers in your part of the world.Ī VPN masks your actual IP address by showing the public internet the IP address of the VPN server you’re using instead of your own. This is how content streaming platforms do geoblocking - restricting content by region.
Your IP address links your device to your ISP as well as to your general geographical location. Just as the postal service uses street addresses to deliver mail to the right people, IP addresses ensure that internet traffic gets sent to the right computers.
Your IP address is a unique set of numbers that identifies your device when you connect to the internet. Why is it important to hide your IP address?

While it's easier to set up than more advanced options, PPTP is full of known security flaws and should be avoided if you’re looking for a secure connection.

PPTP (Point-to-Point Tunneling Protocol) is an obsolete and far less secure protocol still popular with free VPN services. Responsible for creating the VPN connection, L2TP is often combined with IPsec for security. L2TP (Layer 2 Tunneling Protocol) was developed by Microsoft and Cisco as the successor to PPTP (discussed below). But unlike OpenVPN, it isn’t open-source. IKEv2 is especially popular with mobile devices because it can easily switch between mobile data and Wi-Fi networks. Like OpenVPN, IKEv2 uses 256-bit encryption, and both can provide fast connections. IKEv2 (Internet Key Exchange version 2) is an efficient protocol usually combined with the IPsec protocol for security.

VPN connections that use open-source code also allow anyone to verify that the developers aren’t doing anything suspicious themselves. If exploitable vulnerabilities are found, they’re addressed quickly by the community of developers that support it. As an open-source protocol, its source code is available for anyone to verify. Popular for its security and speed, OpenVPN is one of the leading VPN protocols. You can change your VPN protocol in the settings of your VPN app. Each VPN protocol is a combination of encryption methods and transmission protocols. What are VPN protocols?Ī VPN protocol is the set of rules or instructions that create the connection between your device and the VPN’s proxy servers. This level of encryption is so secure that it’s used by banks and governments worldwide - as well as by AVG Secure VPN. While many encryption methods, or algorithms, exist, most VPNs use the 256-bit AES (Advanced Encryption Standard) algorithm. Only your device and the VPN server you’re using can encrypt and decrypt, or unscramble, your data. If anyone examines your VPN connection, they’ll see scrambled data. VPN encryption is the process of using data encryption (encryption protocols) to create a secure tunnel for your data to travel through. Open the VPN app on your computer or mobile device.

Here’s how to use a VPN app to instantly encrypt your data and hide your IP address: What does VPN stand for?Ī VPN is virtual because it’s created digitally - there isn’t a physical cable that reaches from your device directly to the VPN server.Ī VPN is private because it encrypts your data and hides your IP address.Ī VPN is a network because it creates a connection between multiple computers - your device and the VPN server.
That’s why VPN connections boost your privacy and security online.Ī VPN funnels your internet traffic through an encrypted tunnel between your computer and a VPN server. Without a VPN, all your internet traffic is potentially exposed to your internet service provider (ISP), the government, advertisers, or other people on your network. This hides your IP address and secures your data, preventing others from intercepting it. How does a VPN work?Ī VPN works by using encryption protocols to funnel all your internet traffic through an encrypted tunnel - a virtual private network - between your computer and a remote VPN server.
