Network

Diagnose how the hosting server reaches the network: DNS records, HTTP responses, TCP ports, IP addresses, mail services and network interfaces.

Work layer by layer. Resolve the name, inspect the address, test the port or HTTP endpoint, and only then investigate TLS or the application protocol. The result reflects the hosting environment, not your local computer.

Is a domain unreachable? dns shows its records, tcp checks whether a port accepts connections, and curl inspects the HTTP response. These checks run from the hosting server, not from your visitor’s computer.
