Many people get a VPN (Virtual Private Network) app for one explicit reason – to be able to change their perceived IP address. Since lots of data, including geographical location, is tied to IP addresses, changing it through a VPN server will change your perceived locale as well.

While enhanced privacy is a great benefit you can get from changing IP addresses, picking the correct VPN server location will also let you view content that’s usually restricted to that country only.

There’s always more reasons one can have to change their IP address, however.

Today, a VPN (virtual private network) is definitely one of the best ways to safeguard your privacy online. To be able to do so, however, a VPN should first work properly. With companies and governments strengthening surveillance practices, and cyber threats growing fast in 2025, one of the things you must do is to test your VPN connection.

As long as your VPN only looks functioning while it is actually not, there’s a risk of exposing your data and sensitive information without you even realizing it.

With a strong commitment to privacy and transparency, CometVPN works with a mission to make sure that your browsing remains properly secured. But even the best technologies need verification – and that’s where VPN testing comes into the scene.

In this post, we’ll walk you through the main methods of testing your VPN. By the end, you’ll have a clear grasp of what a VPN test is, how to run it properly, and how to sleep easily knowing your personal data is protected 24/7.

Once you get a quality VPN service, you want to use it everywhere - on your smartphone, laptop, TV, console, and all other devices. In such cases, it might be easier to install a VPN on your router than on each device separately.

The configuration varies by router model, but all newer ones support VPN clients. Once you set up a VPN on your router, all devices (even those that might not support it natively) are protected. If you're at least a bit tech-savvy, the instructions below shouldn't be too hard to follow.

Computers talk with each other in numbers and humans in words. That's a simplification, of course, but it gives us a good idea of what DNS servers do — translate words of domain names (cometvpn.com) into numbers of IP addresses (172.67.201.66).

A DNS server can be a privacy hazard as it has to be informed about every website you visit. A private DNS solves this problem by allowing you to use a DNS provider of your choice, possibly with encryption. We explain what private DNS is and how to set it up below.

A VPN, which stands for virtual private network, establishes a digital connection between your computer and a remote server owned by a VPN provider.
