Free methods for accessing blocked websites include using the Tor browser, which offers anonymity and is effective in bypassing censorship, particularly in restrictive regions like Turkey. Changing DNS settings may work for some sites but often fails for others, such as Wikipedia, due to potential interception of DNS requests or blocking of specific IP ranges. Proxy servers can also be utilized; they connect users to sites from countries without restrictions, although they may be slow and temporary. VPNs are popular for encrypting communications and bypassing country restrictions, but their use can be noticeable to network administrators. Additionally, Google’s web cache can be a workaround to access certain pages without revealing the original site visited. However, both Tor and VPNs have limitations regarding traffic monitoring and may not fully protect user privacy.
