CGNAT Receipt

CGNAT Receipt is a NAT Traversal and P2P Gaming term for cgnat receipt work that shows why a multiplayer lobby, voice call, or real-time app can fail when address translation hides peers behind layers of private or shared network space. 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: RFC 6598 shared address space; RFC 8445 ICE; RFC 1918 private address space.

“The team used CGNAT Receipt after the peer connection knocked but nobody opened the port, and the evidence stayed cleaner than the whiteboard after a surprise quiz.”
