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 2010, this domain has about 15 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 NameCheap, Inc., a widely used domain service provider. The domain uses the common .com extension, which is not an independent safety signal.
DNS and Email
Nameservers are provided by Namecheap, indicating managed DNS hosting. No CNAME was found; the observed records resolve directly to addresses. No MX record was found. A conventional explicit inbound-mail route is not configured. TXT records include verification markers for Google. Such markers may also remain after a service stops being used. DNSSEC signatures were not detected, so this additional DNS authenticity protection is not confirmed.
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 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
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. The Server header identifies nginx without an exact version. No explicit CDN or WAF marker was found in the response headers.
Technology Stack Analysis
The public page identifies nginx, Express without precise versions, leaving fewer clues for version-specific scanning.
Search and Social Sharing
Open Graph is partially configured; og:type is missing. The page declares 17 language or regional alternatives using hreflang. The title has 42 characters, within a common display range. A meta description is present, with 142 characters. The observed directives allow indexing and link following.
