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 1993, this domain has about 33 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 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 centralnic.net, indicating managed DNS hosting. MX records point to the emailme.com email service. DNSSEC is enabled, allowing validating resolvers to authenticate signed DNS data.
TLS and Certificates
The public key uses EC with 256 bits. 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 Google Trust Services cloud or CDN ecosystem. The certificate's total validity is about 90 days, consistent with a short renewal cycle.
HTTP and Browser Security
X-Powered-By exposes backend information: ASP.NET. The response lacks these common security headers: Permissions-Policy. The cf-ray 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 identifies cloudflare without an exact version.
Technology Stack Analysis
The public page identifies jQuery, Bootstrap, Google Analytics, Cloudflare, Microsoft IIS 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 42 characters, within a common display range. The observed directives allow indexing and link following.
