Website Overview
An established domain and managed infrastructure suggest continuity of operations and may support dependable delivery, although neither guarantees service quality. Page metadata, canonical configuration and social previews work together to provide more consistent search and sharing presentation.
Domain and Registration
Registered in 1997, this domain has about 29 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 .com extension, which is not an independent safety signal.
DNS and Email
The lowest TTL is 20 seconds, supporting rapid record changes at the cost of more frequent lookups. Nameservers are provided by Akamai Edge DNS, indicating managed DNS hosting. MX records point to the Google Workspace email service. CAA records restrict which certificate authorities are authorized to issue certificates. SPF and DMARC are configured. DKIM status is unknown.
TLS and Certificates
The certificate includes the organization field O'Reilly Media, Inc.. The certificate issuer is DigiCert Inc, a commercial certificate authority. The certificate uses an RSA 2048-bit public key, offering broad client compatibility. The server supplied a complete certificate chain. The certificate is valid for about 198 days in total, with 188 days remaining.
HTTP and Browser Security
The response lacks these common security headers: CSP, Permissions-Policy. 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 contains the custom value istio-envoy. Cookie security attributes are unknown.
Technology Stack Analysis
The public page identifies jQuery, Google Tag Manager, Akamai, Apache without precise versions, leaving fewer clues for version-specific scanning.
Search and Social Sharing
Open Graph is partially configured; og:description is missing. Twitter Card metadata is configured. JSON-LD includes Organization data, helping describe the organization as an entity. The title has 49 characters, within a common display range. A meta description is present, with 138 characters.
