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 27 years of history. That suggests continuity, although ownership and purpose may have changed. The registrar, CSC Corporate Domains, Inc., 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 5 seconds, supporting rapid record changes at the cost of more frequent lookups. Nameservers are provided by colt.net, indicating managed DNS hosting. DNS and provider evidence indicate traffic passes through the Cloudflare CDN, which may support caching and traffic distribution. CAA records restrict which certificate authorities are authorized to issue certificates. No MX record was found. A conventional explicit inbound-mail route is not configured.
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
The response lacks these common security headers: CSP, X-Content-Type-Options, Referrer-Policy, Permissions-Policy, clickjacking protection. No X-Powered-By header was found, reducing one common source of backend fingerprinting information. The cf-ray, 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 identifies cloudflare without an exact version.
Technology Stack Analysis
The public page identifies Cloudflare without precise versions, leaving fewer clues for version-specific scanning.
