Today there are a variety of qualities VPN networks in the market, but for sure no service is perfect. Each VPN providers look to improve the reliability of their service every day. It is stirring how most VPNs keep introducing new advanced privacy features like the VPN Kill Switch feature which is also known as Internet Kill Switch VPN.

VPN Kill Switch Complete GuideFrom time to time the network connection drops and the device go back to the public IP address assigned by the Internet Service Provider (ISP). This brings the risk of the user’s activities being exposed.

It is even worse when the user doesn’t notice if or when this happened. Several VPNs add the internet kill switch VPN feature to their service to counter this problem.

Later we will look at how a kill switch works and some of the VPN services with kill switch features.

What Is A VPN Kill Switch?

A Kill-Switch is an additional security feature that is written into the best VPN services.

The feature ensures that your IP address is never uncovered when the network connection of the VPN server drops.

In simple terms, it is intended to prevent from sending and receiving traffic in case the VPN connection accidentally cuts off.

When activated, the Kill-Switch uses the administrator privileges to automatically cuts off the internet connection immediately if the VPN disconnects. This keeps a user safe from snooping and IP leaks.

Snooping is the interception of the unencrypted traffic.

Why use a Kill Switch?

Even the most reliable VPN services will sometimes experience server down moments.

A Kill-Switch comes last in the line of security to ensure that your IP address is never uncovered or you never transmit packets of unencrypted data. It is therefore important to choose a VPN service that has an Internet Kill-Switch feature.

Although most users don’t need such levels of security, it is important to have an alternative for users whom security is a major concern.

How A Kill Switch Works

A Kill-Switch can be compared to a spy that continuously observes your network connection for any change in either bandwidth, status or IP address.

If the Kill-Switch notices any change (it could be a drop in the VPN connection), it immediately cuts off your internet connection until the VPN connection is restored or you shut down the VPN.

The reaction of the Kill-Switch is usually virtually instant, to prevent your device from defaulting to the public IP address assigned by the Internet provider.

Types Of Kill Switches

System Level Kill Switch

System level Kill-Switch is the simplest and the most popular Kill-Switch selection.

When it is enabled, a system kill switch absolutely blocks internet connection to the entire computer until the VPN connection is restored or by resetting the network adapter.

Usually it is a brute force technique with a little of finesse. A system kill switch is very effective at avoiding IP leaks.

Enabling a system kill switch is generally easy, as it only entails selecting a check box in the VPN.

Below is a demonstration of enabling a Kill-Switch in Private Internet Access software.

Application Level Kill Switch

Application level kill switch is a type on a kill switch that allows you to choose the specific applications you want to kill when the kill-switch activates.

The way I see it, it is more flexible compared to the system level kill-switch because it allows the user more control on how the switch operates.

The common applications/programs that you may want to close include:

  • The browsers (Google Chrome, Mozilla, Opera Mini etc.)
  • Gmail app.
  • Skype.
  • Torrent Client (Bit torrent, Utorrent, Vuze etc.)

Resetting A Kill Switch

When users don’t know how a Kill-Switch works they tend to send complaints to the VPN service providers.

Most users doesn’t understand the strength of a kill-switch and the things they ought to do to restore internet connection.

For you to regain connection you should take one of the following steps:

  • Restore connection to the VPN
  • Reset the DHCP settings for the Network adaptor.

Resetting your DHCP settings is easy. You can achieve that by following these simple steps:

  • Right click the network/Wifi icon in the system tray and run the trouble-shooter.
  • When the trouble-shooter return a “Cannot Reach DHCP gateway” message, click fix and it will automatically reset.

Other Solutions To Disconnections

Other than the Kill-Switches, there are many other choices to stay safe and protect your IP address if the VPN network is not reliable. The most popular options are:

VPNetMon

VPNetMon is a free program that blocks unsafe connections in case the VPN connection drops.

The program kills specific applications when the VPN connection goes down. The program is ideal for most users because it does not block internet use to the whole device: just kills some apps that could uncover the IP address over the insecure connection.

The program also has the capability of auto dialing your VPN using PPTP or L2PT.

VPN Watcher

Just like VPNetMon, VPN Watcher observes the VPN connection. In the event it goes down it kills the applications that could reveal the IP address over the unprotected network.

But this tool is not free, it will cost a user $9.95.

Do I need a Kill Switch?

Whether to activate a Kill-Switch or not is a personal decision to make.

It all depend on the reason you bought a VPN for in the first place.

If security is a major concern to you and that you may never want to uncover your IP address, it is important to always activate the internet kill-switch VPN when accessing the internet.

When Kill Switch Is A Must

  • Torrents users
  • People who need to remain anonymous (Like activists)
  • People holding confidential documents
  • Pokers

On the other hand people using VPN to unblock Geo-restrictions should be less troubled.
