US Patent 11916969 Privacy preservation in network connections

Methods and systems provide for reducing privacy leaks in DNS request by using a private DNS service. The private DNS service provides for matching a level of privacy provided by a type of communication protocol to a level of privacy desired or required for a particular client communication. When the DNS service determines that an intended communication protocol does not supply at least the level of privacy desired for a particular communication, the private DNS service may initiate the creation of a connection with the desired level of privacy.
