Google announced general availability of its Public DNS-over-HTTPS service Wednesday. The move is a culmination of three years of Google fine-tuning DNS over HTTPS, otherwise known as DoH. DoH is based on the Internet Engineering Task Force s RFC 8484 standard. The standard has not yet been ratified by the IETF, but as more internet stakeholders adopt it, it is closer it is to formally becoming a DoH standard. In April of 2018, experts said the standard could become adopted in a matter of weeks.
