. No Public DNS Records, But Still Observed on Shodan

If these domains are not resolvable via DNS, but appear on Shodan with SSL certificates, this means:

They are online and actively responding to network scans.

They are not resolving via public DNS but are accessible via direct IP requests (possibly exposed via an IP-based configuration).

A reverse DNS lookup may not return results, but the service itself is still live.

3. 404 Not Found on Port 443 (HTTPS)

This suggests the web server is responding to requests but refusing to serve content (likely because access is restricted).

Possible explanations:

Access Control Restrictions – The server might only allow requests from whitelisted IPs or internal users (e.g., VA networks, VPNs).

Misconfigured or Intentional Limited Exposure – The server may be accidentally left exposed but is not serving any content externally.

Load Balancer or Reverse Proxy – There could be a proxy layer that only forwards traffic internally.
