Firewalls, NAT, access lists, routing, geoblocking, rate limiting and source-address policies can make the hosted result differ from a connection attempted on the user’s own network. An open result confirms only that the hosted service connected at that moment.

Important: Do not rely on this result alone for purchasing, configuration, security, safety, compliance, contractual or fault-diagnosis decisions. Results can be incomplete, delayed, misleading or wrong. Verify important findings with the relevant provider, manufacturer documentation and an appropriate independent test or qualified professional.
