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.

172.16/12 Checkpoint is a DNS and IP Addressing term for 172.16/12 checkpoint work that explains how names, records, address ranges, and routing boundaries make the internet findable without exposing private networks as public destinations. 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.
