A Virtual Private Network is simply a group of private, encrypted connections hosted on a network that is bigger (typically the Internet). Consider it like a tunnel that takes you to another location online. Let us say you also would like to log into the office network to access files or software and you’re at home put behind a corporate firewall. Or you also would like so you can see Dallas Buyers Club to get a Netflix server in Denmark.

It is also more private than DNS masking, because now, not your ISP will be aware of what you have been up to, only that you have been linking to one end of a VPN. Is a puzzle to them, where you come out on the other side. On the flip side, you frequently lose some of your bandwidth, which means that your streaming speed can suffer.
