Abstract
A method for adding a blacklisted site to a whitelist includes requesting a blacklisted site via a network, the blacklisted site having a domain name of the format <blocked-domain>. The method includes generating queries for an encoded domain, the encoded domain being of the format <nonce>.<hash>.<blocked-domain>.<static domain>, sending the queries to a recursive DNS server, and sending responses based on the queries to a cache of a web browser. The method includes requesting by the web browser the blacklisted site, adding the blacklisted site to the whitelist, sending an IP address corresponding to the blacklisted site to the web browsers, and accessing the blacklisted site.
