Website Overview
Several search or sharing settings need attention. Together they may make snippets, preview images or preferred URLs less consistent across platforms. An active inbound-mail setup with incomplete authentication may leave the domain more open to impersonation. Provider hosting alone does not close that gap.
Domain and Registration
Unknown
DNS and Email
The observed email authentication setup is incomplete: DMARC is missing. Nameservers are provided by zzu.edu.cn, indicating managed DNS hosting. MX records point to the zzu.edu.cn email service. No CNAME was found; the observed records resolve directly to addresses. The lowest observed DNS TTL is 36000 seconds.
TLS and Certificates
The certificate includes the organization field 郑州大学. The certificate issuer is DigiCert Inc, a commercial certificate authority. The certificate uses an RSA 2048-bit public key, offering broad client compatibility. The server supplied a complete certificate chain. The certificate is valid for about 198 days in total, with 30 days remaining.
HTTP and Browser Security
The response lacks these common security headers: HSTS, CSP, Referrer-Policy, Permissions-Policy. No X-Powered-By header was found, reducing one common source of backend fingerprinting information. No obvious internal addresses or debug information were found in the headers. The Server header contains the custom value *********. No explicit CDN or WAF marker was found in the response headers.
Technology Stack Analysis
The public page identifies jQuery without precise versions, leaving fewer clues for version-specific scanning.
Search and Social Sharing
No homepage canonical URL was detected. If duplicate URLs exist, consolidation may be less explicit. No Open Graph metadata was detected, so social previews may depend on platform inference. The title has 4 characters, within a common display range. A meta description is present, with 34 characters. The observed directives allow indexing and link following.
