Considering Your VPN Provider
VPN blockers come in a variety of shapes and sizes. The most frequent way of VPN blocking is to configure a site to ban recognized VPN IP addresses. Because there are so many VPNs and they change their IP addresses so quickly, it is difficult to ban every single VPN's IP address. This is why smaller VPNs often perform better than larger ones since their IP addresses are not yet known to the limiting organizations, and why VPNs constantly add and change their IP addresses.
A VPN, or Virtual Private Network, is a service that provides you with an anonymous, private internet connection via one of the VPN's servers located across the world. This implies that your ISP, phone company, or government will be unable to monitor your activities, and websites and advertising will be unable to readily trace your online behavior.
