Q:

How do you unblock access to a website?

A:

Quick Answer

One way to access blocked websites is using a virtual private network. When connected to a VPN, all communication passes through a VPN server, which then redirects the traffic to the destination server. This hides the Internet Protocol address that initiates a request from the destination server, and allows users to get around website filtering so that they can access blocked websites.

Proxy websites allow users to access blocked websites without having to install any software on their computers. When accessing a website through a proxy website, a user's web browser sends a request to the proxy server on which the proxy website resides, which then redirects the request to the destination website. To the user's Internet service provider, the proxy server is the destination of the user's request, while to the destination server, the request originates from the proxy server.

When using Tor clients to access websites, the requests travel through a series of random servers before they reach their destinations. All servers involved don't know the actual IP address that originates a request, and this allows users to access blocked websites. In addition, changing the domain name server on a device may bypass website filtering that happens at the DNS level. By setting a custom DNS, such as the Google Public DNS, on a device, users can override the rules implemented by the default DNS.
