libros63.com

We performed a comprehensive analysis of libros63.com on 2026-07-04. The website returned an HTTP 200 status code with a server response time of 7507ms. The page is served over HTTP/2 protocol with Gzip compression enabled, achieving approximately 0.1% size reduction. The total page weight is 64 KB. The website uses a secure HTTPS connection with a valid SSL certificate issued by Sectigo Limited (OV type). The connection is encrypted using TLS 1.3 with the TLS_AES_128_GCM_SHA256 cipher suite and sha256WithRSAEncryption signature algorithm. The certificate covers 2 domain(s) (Subject Alternative Names) and expires on 2026-12-24, which is 173 days from now. The security headers analysis reveals a score of 85/100 (good). The following security headers are properly configured: Content-Security-Policy, Strict-Transport-Security (HSTS), X-Frame-Options, X-Content-Type-Options, and Referrer-Policy. However, the site is missing Permissions-Policy, which could expose the site and its users to cross-site scripting (XSS), clickjacking, and other web-based attacks. Our technology detection scan identified 7 technologies across 7 categories powering libros63.com. The detected stack includes Vue.js, Bootstrap, reCAPTCHA v3, Cloudflare, Google Fonts, jQuery, and Font Awesome. The UI is built with Vue.js. Based on our comprehensive analysis of domain age, SSL configuration, email authentication, security headers, and blacklist status, libros63.com receives an overall trust score of 80/100, classified as "Very Likely Safe".

After conducting a thorough safety and legitimacy analysis, libros63.com receives a trust score of 80/100, which places it in the "Very Likely Safe" category. This score is calculated by evaluating multiple factors including SSL certificate validity, domain registration history, email authentication protocols, security header configuration, and blacklist status across major threat intelligence databases. The analysis identified several positive trust signals: a valid HTTPS connection protecting data in transit, HSTS (HTTP Strict Transport Security) enforcement preventing protocol downgrade attacks, a valid SSL certificate issued by Sectigo Limited with 173 days until expiration, SPF (Sender Policy Framework) email authentication preventing email spoofing, and DMARC email authentication with a none policy. Areas of concern include: the domain's WHOIS information is hidden behind a privacy service, making it harder to verify the owner's identity and DNSSEC is not enabled, leaving DNS queries vulnerable to spoofing attacks. While these issues don't necessarily indicate malicious intent, they represent areas where the website's security posture could be improved. We checked libros63.com against 8 major blacklist databases including Google Safe Browsing, Phishtank, Urlhaus, Openphish, Dnsfilter, Spamhaus Dbl, Surbl, and Virustotal. The domain passed all 8 checks with a clean status, meaning it has not been flagged for phishing, malware distribution, spam, or other malicious activities by any of the tested threat intelligence providers.

libros63.com delivers its homepage in 7507ms (server response time), which is considered slow by industry standards. The total page weight is 64 KB, and we detected 172 resource requests loading assets from 11 third-party domains. A high number of third-party domains can significantly impact page load time due to additional DNS lookups and TLS handshakes required for each domain. The website uses Gzip compression for text-based assets, achieving an estimated 0.1% reduction in transfer size. This reduces bandwidth usage and improves page load times, especially for visitors on slower connections. Asset minification status: 1 out of 20 CSS files and 8 out of 17 JavaScript files are minified. Minifying the remaining 28 unminified file(s) could further reduce page weight by 10-30% for those assets. Minification is a best practice that reduces download sizes without affecting functionality. From an environmental perspective, each page view of libros63.com produces approximately 0.03g of CO₂, earning a carbon rating of A. This places the website among the cleanest on the web, demonstrating efficient use of server resources and optimized content delivery. For reference, the average web page produces about 0.5g of CO₂ per page view. The page weight of 64 KB is the primary factor in this calculation. Core Web Vitals data from the Chrome User Experience Report (CrUX) is not available for libros63.com. This typically means the site doesn't have enough real-world Chrome user traffic to generate statistically significant field data, or the domain is not included in the CrUX dataset. Core Web Vitals (LCP, INP, CLS) are important Google ranking factors that measure real user experience.

libros63.com resolves to the IPv4 address 217.18.163.21, but does not support IPv6. IPv6 adoption is increasingly important as IPv4 address space becomes exhausted, and some ISPs and regions are transitioning to IPv6-only connectivity. The domain has 1 A record(s) configured. The domain name system is managed by 2 name servers: ns1.libros63.com and ns2.libros63.com. Having 2 name servers provides good redundancy — if one fails, the others can continue serving DNS queries. The choice of name servers often indicates the DNS hosting provider or CDN service being used. Email for libros63.com is handled by libros63.com with 1 MX records configured: mail.libros63.com. Multiple MX records provide failover redundancy — if the primary mail server is unavailable, email will be routed to the next available server. SPF (Sender Policy Framework) is configured, which specifies which mail servers are authorized to send email on behalf of this domain. This helps prevent email spoofing and improves email deliverability. DMARC (Domain-based Message Authentication, Reporting and Conformance) is configured with a none policy — a monitoring-only setting that doesn't enforce any action on unauthorized emails. DKIM was not detected. Without DKIM, recipients cannot cryptographically verify that emails claiming to be from this domain are authentic. DNSSEC is not enabled for libros63.com. While not critical for most websites, DNSSEC adds an important security layer by ensuring DNS responses haven't been tampered with during transit. Enabling DNSSEC is recommended for domains handling sensitive data or financial transactions.

The homepage of libros63.com contains 509 words of visible text content. This is a moderate amount of content. The page is structured with 4 H2 headings, 3 H3 headings, 0 H4 headings. The page includes 16 images. 6 images (38%) are missing alt text attributes, which is a significant concern for both accessibility and SEO. Screen readers rely on alt text to describe images to visually impaired users, and search engines use alt text to understand image content. Only 62% of images have proper alt text — we recommend adding descriptive alt attributes to all images.
