Public destinations
All resolved addresses are checked before connecting. A private or reserved address in the answer blocks the entire scan; connections use the exact validated IPs.

Resolution uses this server’s configured DNS resolver. Connection timings are single observations, not ping latency. Only one IPv4 and one IPv6 address are sampled, and no HTTP request is sent. A timeout or refusal is inconclusive about availability elsewhere.
Resolved addresses
192.0.2.102001:db8::10
192.0.2.10 · port 80:Connected
What we observed
Sample TCP connection established.
TCP connection time: 32 ms. TLS handshake time is not included in this number.
What to review
Port 80 may be deliberately unavailable. Where HTTP is offered, use the security scanner to check its HTTPS redirect.
192.0.2.10 · port 443:Connected
What we observed
Sample TLS handshake and certificate validation succeeded.
TCP connection time: 35 ms. TLS handshake time is not included in this number.
What to review
Check HTTPS bindings, certificate hostname and trust, certificate renewal, firewall rules, and IPv6 routing when appropriate. A successful handshake is not a full TLS configuration audit.
2001:db8::10 · port 80:Inconclusive
What we observed
Sample IPv6 connection timed out.
What to review
Port 80 may be deliberately unavailable. Where HTTP is offered, use the security scanner to check its HTTPS redirect.
2001:db8::10 · port 443:Inconclusive
What we observed
Sample IPv6 connection timed out.
What to review
Check HTTPS bindings, certificate hostname and trust, certificate renewal, firewall rules, and IPv6 routing when appropriate. A successful handshake is not a full TLS configuration audit.

Bounded checks
Four connections maximum, with four-second per-connection limits. No arbitrary port ranges, ICMP ping, traceroute, or internal network scanning.
Certificate checks
TLS uses the submitted hostname and normal certificate chain validation. Revocation is not checked; missing intermediate certificates can cause validation to fail.
