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
The domain has about 3 years of registration history; its current configuration provides more context than age alone. The domain uses the common .cn extension, which is not an independent safety signal.
DNS and Email
The observed email authentication setup is incomplete: DMARC is missing. The lowest TTL is 60 seconds, supporting rapid record changes at the cost of more frequent lookups. Nameservers are provided by Alibaba Cloud DNS, indicating managed DNS hosting. MX records point to the Alibaba Mail email service. DNSSEC signatures were not detected, so this additional DNS authenticity protection is not confirmed.
TLS and Certificates
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. No organization name is present in the certificate; the available fields are consistent with domain validation. The certificate is valid for about 394 days in total, with 193 days remaining.
HTTP and Browser Security
X-Powered-By exposes backend information: Nuxt. The checked browser-security headers were not detected, leaving fewer explicit browser-side safeguards. The via response header indicates a CDN or caching proxy in the delivery path. No obvious internal addresses or debug information were found in the headers. The Server header contains the custom value Tengine.
Technology Stack Analysis
The public page identifies Nuxt 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. Open Graph is partially configured; og:image is missing. The title has 45 characters, within a common display range. A meta description is present, with 159 characters. The observed directives allow indexing and link following.
