Connectivity Check
Definitions
Connectivity Check is a NAT Traversal and P2P Gaming term for a STUN-based test used by ICE agents to verify whether a candidate pair can actually carry traffic between peers. 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 Connectivity Check was the ping-pong tryout before the game invited everyone into the lobby.”
