Website Overview
An established domain and managed infrastructure suggest continuity of operations and may support dependable delivery, although neither guarantees service quality. Several search or sharing settings need attention. Together they may make snippets, preview images or preferred URLs less consistent across platforms.
Domain and Registration
Registered in 2005, this domain has about 20 years of history. That suggests continuity, although ownership and purpose may have changed. 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 1 seconds, supporting rapid record changes at the cost of more frequent lookups. Nameservers are provided by DNSPod, indicating managed DNS hosting. DNS and provider evidence indicate traffic passes through the Amazon CloudFront CDN, which may support caching and traffic distribution. MX records point to the Tencent Enterprise Mail email service. The CNAME points to d1er8zidj5j6tm.cloudfront.net, associated with Amazon CloudFront.
TLS and Certificates
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 was issued within the Amazon cloud or CDN ecosystem. The certificate is valid for about 197 days in total, with 99 days remaining.
HTTP and Browser Security
The Server header exposes the software version: npc/1.13.6.2. This makes version-targeted checks easier, but is not proof of an exploitable vulnerability. The checked browser-security headers were not detected, leaving fewer explicit browser-side safeguards. No X-Powered-By header was found, reducing one common source of backend fingerprinting information. The x-cache, 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.
Technology Stack Analysis
The public page identifies Amazon CloudFront without precise versions, leaving fewer clues for version-specific scanning.
Search and Social Sharing
No homepage meta description was detected, leaving snippet selection more dependent on page text. 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 5 characters, within a common display range. The observed directives allow indexing and link following.
