Authoritative DNS infrastructure refers to the secured and resilient systems that respond to DNS queries with verified domain data.
DNS resolution is a free service provided when a domain name is registered. Some companies specialise in advanced DNS services for web hosting companies and large companies, such as providing faster DNS resolution, increasing DNS security or blocking advertising trackers. The major players of the market are large US companies.
