DNS
Definitions
DNS is a DNS and IP Addressing term for the Domain Name System, the internet naming system that maps human-readable names to records such as addresses, mail exchangers, aliases, and reverse lookups. It helps people and agents name the signal, source, and safe next step without pretending an automation, campaign, DNS record, RFC, or network path did more than the evidence shows. Source context: IETF DNS technology; RFC 1918 private address space; RFC 6598 shared address space.
“DNS told the browser where to go, because typing raw IPs all day would make everyone dramatically tired.”
