Google launched Google Public DNS in 2009 at a time when many Internet companies started to hop on the DNS bandwagon. Some companies exited the DNS business again, Symantec retired Norton ConnectSafe (DNS) in 2018, while others such as Cloudflare, Verisign, Quad9 DNS or AdGuard DNS launched in recent years.
Google claims that its service is the "world's largest public Domain Name Server (DNS) recursive resolver"; it turns domain names into IP addresses required for communication on the Internet.
DNS-over-TLS and DNS-over-HTTPS are two approaches to making DNS requests more private by using encryption. One of the main differences between the two implementations is the port that is used. DNS-over-TLS uses port 853, DNS-over-HTTPS the standard HTTPS port 443.
