xn--h1adlhdnlo2c.xn--p1ai

We performed a comprehensive analysis of xn--h1adlhdnlo2c.xn--p1ai on 2026-06-30. The website returned an HTTP 200 status code with a server response time of 3606ms. The page is served over HTTP/1.1 protocol with Gzip compression enabled, achieving approximately 60.0% size reduction. The total page weight is 138 KB. The website uses a secure HTTPS connection with a valid SSL certificate issued by Let's Encrypt (DV type). The connection is encrypted using TLS 1.2 with the ECDHE-ECDSA-AES256-GCM-SHA384 cipher suite and ECDSA-SHA384 signature algorithm. The certificate covers 7 domain(s) (Subject Alternative Names) and expires on 2026-09-17, which is 79 days from now. The security headers analysis reveals a score of 0/100 (poor). No security headers are configured, which is a significant security concern. However, the site is missing Content-Security-Policy, Strict-Transport-Security (HSTS), X-Frame-Options, X-Content-Type-Options, Referrer-Policy, and 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 3 technologies across 3 categories powering xn--h1adlhdnlo2c.xn--p1ai. The detected stack includes Google Analytics 4, reCAPTCHA v3, and jQuery 2.2.4.. Based on our comprehensive analysis of domain age, SSL configuration, email authentication, security headers, and blacklist status, xn--h1adlhdnlo2c.xn--p1ai receives an overall trust score of 65/100, classified as "Likely Safe".

After conducting a thorough safety and legitimacy analysis, xn--h1adlhdnlo2c.xn--p1ai receives a trust score of 65/100, which places it in the "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, a valid SSL certificate issued by Let's Encrypt with 79 days until expiration, SPF (Sender Policy Framework) email authentication preventing email spoofing, and DNSSEC providing authenticated DNS responses. Areas of concern include: the absence of a Content-Security-Policy header, which leaves the site more vulnerable to cross-site scripting (XSS) attacks, no X-Frame-Options header, which could allow the site to be embedded in malicious iframes (clickjacking), missing Referrer-Policy, potentially leaking URL information to third parties, and the domain's WHOIS information is hidden behind a privacy service, making it harder to verify the owner's identity. While these issues don't necessarily indicate malicious intent, they represent areas where the website's security posture could be improved. We checked xn--h1adlhdnlo2c.xn--p1ai 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.

Our technology detection engine scanned xn--h1adlhdnlo2c.xn--p1ai and identified 3 distinct technologies across 3 categories.

xn--h1adlhdnlo2c.xn--p1ai delivers its homepage in 3606ms (server response time), which is considered slow by industry standards. The total page weight is 138 KB, and we detected 263 resource requests loading assets from 27 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 60.0% reduction in transfer size. This reduces bandwidth usage and improves page load times, especially for visitors on slower connections. Asset minification status: 2 out of 9 CSS files and 8 out of 13 JavaScript files are minified. Minifying the remaining 12 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 xn--h1adlhdnlo2c.xn--p1ai produces approximately 0.07g 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 138 KB is the primary factor in this calculation. Core Web Vitals data from the Chrome User Experience Report (CrUX) is not available for xn--h1adlhdnlo2c.xn--p1ai. 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.

xn--h1adlhdnlo2c.xn--p1ai resolves to the IPv4 address 84.201.188.68, 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: megan.ns.cloudflare.com and yadiel.ns.cloudflare.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 xn--h1adlhdnlo2c.xn--p1ai is handled by yandex.net with 1 MX records configured: mx.yandex.net. 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 is not configured, leaving the domain vulnerable to email spoofing and phishing attacks that impersonate this domain. DKIM was not detected. Without DKIM, recipients cannot cryptographically verify that emails claiming to be from this domain are authentic. DNSSEC is enabled for xn--h1adlhdnlo2c.xn--p1ai, providing an additional layer of security by cryptographically signing DNS records. This prevents DNS cache poisoning and man-in-the-middle attacks that could redirect visitors to malicious websites.

The homepage of xn--h1adlhdnlo2c.xn--p1ai contains 2,872 words of visible text content. This is a substantial amount of content that provides good opportunities for search engine indexing.

A compelling meta description with a clear call-to-action can significantly improve click-through rates from search results. The canonical url is correctly set to https://xn--h1adlhdnlo2c.xn--p1ai, preventing duplicate content issues and a favicon is configured. Open Graph meta tags are configured with 3/4 recommended fields: OG title ("Урок Цифры — всероссийский образовательный проект в сфере ци..."), OG image (social sharing thumbnail), OG type (website/). These tags control how the page appears when shared on Facebook, LinkedIn, and other social media platforms that support the Open Graph protocol. A Twitter Card of type summary_large_image is configured, which controls how links appear when shared on Twitter/X.
