A VPN can be useful if you want to access websites, watch videos, or transfer file content to or from other countries that ban foreign IP addresses. For example, if you want to watch a streaming movie that is only available in the Netherlands, simply open your VPN software and choose an IP address location in the Netherlands. The VPN will make it appear to the movie streaming service as if you're online in that country. However, be aware that streaming video service providers are becoming increasingly sophisticated at detecting VPN use and blocking you. Be sure to research what you can and cannot do with a specific VPN.
