If you already have a VPN up and running, sometimes you’ll just want to disable it. Many users run their virtual private network continuously as most modern VPN software don’t impede network or computing performance by much.

Other users, however, only use a VPN service when they want to stream content that wouldn’t be regularly available. They then turn off the VPN app as soon as they’re done.

While you can turn off a VPN on any device with relative ease, there’s a few ways the application can be implemented.

A VPN (Virtual Private Network) is a tool that protects your digital safety while browsing, traveling, and in any other situations where you use an internet connection. People rely on a VPN connection to secure their network, bypass geo-restrictions, and protect their data.

However, VPNs are not without their hurdles. After reading this article, you will understand why is your VPN not connecting, how to troubleshoot most VPN server connectivity problems, and how to fix them quickly.

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.

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 firewall is a security system that is meant to protect your devices from harmful files, viruses, and hacks online. An important thing to understand is that there are more than one type of firewall out there, and they have different levels and features of security.

In this article, you will understand everything there is to know about SPI firewalls, which offer more robust security by ensuring that only safe online traffic is allowed through.

We’re all familiar with the pain of sudden internet connection problems, instability, and the constant website crashes. And while this could just be an innocent connection loss, it could also be a sign of an IP fragmentation attack.

Although a lesser-known threat, it’s a type of cyber attack that exploits the way internet protocols handle data transmission to evade firewalls, disrupt services, and infiltrate networks undetected.

If successful, a slowed internet would be the least of your worries – there would also be a risk of major application crashes, and worst still, malicious and unauthorized data breaches. That’s why it’s important to be informed and know how to protect your device properly.
