Website Overview
An established domain and managed infrastructure suggest continuity of operations and may support dependable delivery, although neither guarantees service quality.
Domain and Registration
Registered in 1998, this domain has about 28 years of history. That suggests continuity, although ownership and purpose may have changed. The registrar, MarkMonitor Information Technology (Shanghai) Co., Ltd., specializes in corporate domain and brand management, suggesting attention to domain asset protection. Transfer-protection status is present, helping reduce the risk of unauthorized domain transfers. The domain uses the common .com extension, which is not an independent safety signal.
DNS and Email
The lowest TTL is 60 seconds, supporting rapid record changes at the cost of more frequent lookups. Nameservers are provided by qq.com, indicating managed DNS hosting. MX records point to the Tencent Enterprise Mail email service. No CNAME was found; the observed records resolve directly to addresses. SPF and DMARC are configured. DKIM status is unknown.
TLS and Certificates
The certificate includes the organization field Shenzhen Tencent Computer Systems Company Limited. 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 391 days in total, with 130 days remaining.
HTTP and Browser Security
X-Powered-By exposes backend information: Express. The checked browser-security headers were not detected, leaving fewer explicit browser-side safeguards. No obvious internal addresses or debug information were found in the headers. No explicit CDN or WAF marker was found in the response headers. No CORS permission header was found, so browsers normally restrict cross-origin script access.
Technology Stack Analysis
The public page identifies WordPress, Express without precise versions, leaving fewer clues for version-specific scanning.
Search and Social Sharing
No Open Graph metadata was detected, so social previews may depend on platform inference. The title has 5 characters, within a common display range. A meta description is present, with 70 characters. The observed directives allow indexing and link following. No Generator meta tag is publicly exposed.
