A Complete Guide about VPN: All You Need To Know

Do you want to watch Netflix in another country, or hide your web activity from your ISP (Internet Service Provider), or bypass government restrictions? The one thing that can help you here is the VPN – Virtual Private Network. VPNs are valuable and straightforward tools. But out there are so many people who aren’t aware of them at all.

Here is the guide about Free VPN, which can clear all your ambiguities!

What is a VPN in Simple Words?

VPNs are virtually a combination of servers you link to through your ISP (Internet Service Provider). Once you have created an association with your VPN, a strategy called tunnelling started. Then the servers behave as your essential home on the internet. As you tunnelled in, any spy agency or your ISP can’t trace your location and detect what you’re downloading or browsing.

How does a VPN work?

Encryption protocols are used to run a VPN, and funnelling is done between a remote VPN server or your computer to pass your internet traffic through an encrypted tunnel, i.e. a VPN.

Its protocols include:

  1. PPTP
  2. SSTP
  3. OpenVPN (Most Common)
  4. L2TP/IPSec
  5. IKEv2

What Happens When you don’t Use a VPN?

If you don’t use a VPN, all your internet traffic is potentially revealed to the advertisers, the government, internet service provider (ISP), or other persons on your network. That’s why VPN plays a significant role in boosting your secrecy and safety online.
