Tutorial: How to Check and see if your VPN Connection is Secure

VPN’s can be very easy to set up. In this tutorial you are going to test your VPN connection, and see if it’s actually secured. When you turn on a VPN it is very simple, you may just hit connect, it tests the connection, then finally connects.

Now you need to ask yourself this few questions;

Is it really securing that connection and encrypting it?

Is your ISP getting leaked queries?

Now lets check and see if your VPN Connection is Secure.

A VPN consists of an IP address, a DNS, and keeping everything inside their given IP and DNS. This means that when you connect to YouTube.com, the VPN should secure your entire connection, even when using flash.

Once connected, you should be assured that flash player queries are not getting leaked a from your real computers IP to identify you. This also applies with Java. When playing games with Java, is your real computer or location identifiable?

Also in keeping these applications secure, the VPN needs to keep all your DNS queries within the VPN’s given DNS. This is where many VPN providers fall short. Most VPN providers offer no protection against DNS leaks (except Private Internet Access), and most don’t even mention it. DNS leaks are a huge security flaw. Most if not all of your http://queries can be leaked to your ISP.

This is what a DNS leak looks like.

As you can see, a DNS leak can be a huge vulnerability. It doesn’t defeat the purpose of a VPN, but it still tells your ISP what websites you visit. A VPN’s objective is to secure you from your ISP, and keep your traffic hidden. If your service provider is still seeing what websites you visit, it defeats the entire purpose as your ISP is still logging your data.

Now lets see if your VPN is working, and securing you?

Many tools online helps to check this, but not many that do it right. Below are some of the best tools to check your VPN configuration.

IP address test – To start, go with a simple IP check. Make sure that the location shown on the map is not your actual home location, and that it’s your VPN providers server.

  • Extended IP address test – This test is where it really counts. This checks your Flash, Java, and DNS. Make sure the flash, and java IP’s/DNS’s are not yours leaking and ensure they are the VPN providers. Check the IP’s and put them into a search engine like DuckDuckGo. Many VPN providers point their DNS to Google. Google is located in Mountain View, California. But if the DNS leaks something similar to127.0.0.1.verizionfios.direct, and you are using Verizion fios, your queries are begin leaked.
  • IP test for Bittorrent (checkmytorrentip.com- Delinked for security reasons) (now dead) – This will test your Bittorrent/P2P IP. Once you hit start, it will download a test .torrent file.Open the .torrent file in your bittorrent client. Once opened, let it connect and download. Once it does, the website should tell you what IP is being shown to others in a bittorent swarm. It should be showing your VPN’s IP.
  • DNS leak check (here is another optional checker)-Probably one of the most important ones aside from the VPN begin connected.Check for possible leaks. Click check, and let it load the IP’s/DNS’s. If any point to your home DNS, or look something like verizion fios, your queries are begin leaked to your ISP. Again, if you don’t notice them, check the IP on DuckDuckGo. If they are right next to your real location, most of the time, queries are being leaked.
