FAQ
Can you ping with ICMP?+
No. Browsers cannot send ICMP. Our Ping Test measures HTTP(S) latency instead.
Does WHOIS use classic WHOIS protocol?+
We use RDAP (Registration Data Access Protocol) over HTTPS — the modern replacement for many WHOIS lookups.
Can I scan any TCP port?+
Browsers block arbitrary TCP. Port Checker probes common HTTP/HTTPS ports (80, 443, 8080, 8443).
