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 2014, this domain has about 11 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 registrar is GoDaddy.com, LLC, a widely used domain service provider. The domain uses the common .net extension, which is not an independent safety signal.
DNS and Email
Nameservers are provided by usja.net, indicating managed DNS hosting. MX records point to the usja.net email service. No CNAME was found; the observed records resolve directly to addresses. SPF and DMARC are configured. DKIM status is unknown. DNSSEC signatures were not detected, so this additional DNS authenticity protection is not confirmed.
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 by Let's Encrypt, commonly associated with automated certificate services. The certificate's total validity is about 89 days, consistent with a short renewal cycle.
HTTP and Browser Security
The response lacks these common security headers: CSP, Referrer-Policy, Permissions-Policy, clickjacking protection. 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 identifies nginx without an exact version. Cookie security attributes are unknown.
Technology Stack Analysis
The public page identifies WordPress, Google Analytics, nginx 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 30 characters, within a common display range. A meta description is present, with 126 characters. The observed directives allow indexing and link following.
