bymath.net

We performed a comprehensive analysis of bymath.net on 2026-06-28. The website returned an HTTP 404 status code with a server response time of 23111ms. The page is served over HTTP/2 protocol with Gzip compression enabled, achieving approximately 60.0% size reduction. The total page weight is 12 KB. Warning: The website does not have a valid SSL certificate. Visitors may see security warnings in their browser, and data transmitted to and from this website is not encrypted. The security headers analysis reveals a score of 50/100 (moderate). The following security headers are properly configured: Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options. However, the site is missing Strict-Transport-Security (HSTS), 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 4 technologies across 4 categories powering bymath.net. The detected stack includes Bootstrap 5.2.0, Google Analytics 4, Google Fonts, and jQuery 3.6.0.. Based on our comprehensive analysis of domain age, SSL configuration, email authentication, security headers, and blacklist status, bymath.net receives an overall trust score of 64/100, classified as "Likely Safe".

After conducting a thorough safety and legitimacy analysis, bymath.net receives a trust score of 64/100, 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, SPF (Sender Policy Framework) email authentication preventing email spoofing, and DMARC email authentication with a none policy. Areas of concern include: missing Referrer-Policy, potentially leaking URL information to third parties, 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 bymath.net 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 bymath.net and identified 4 distinct technologies across 4 categories. This analysis is performed by examining HTTP response headers, HTML source code patterns, JavaScript library fingerprints, CSS framework signatures, and DNS records. CSS Framework: Bootstrap (version 5.2.0) — provides the styling and responsive layout system for bymath.net. Analytics: Google Analytics 4 — tracks visitor behavior and provides traffic insights for bymath.net. Fonts: Google Fonts — delivers web fonts for typography for bymath.net. JavaScript Library: jQuery (version 3.6.0.) — provides utility functions and DOM manipulation for bymath.net. We also extracted the following tracking identifiers: Google Analytics 4 Measurement ID G-F4103GN378. These IDs can be used to identify other websites operated by the same organization.

bymath.net delivers its homepage in 23111ms (server response time), which is considered slow by industry standards. The total page weight is 12 KB, and we detected 37 resource requests loading assets from 4 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: 1 out of 5 CSS files and 2 out of 4 JavaScript files are minified. Minifying the remaining 6 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 bymath.net produces approximately 0.01g 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 12 KB is the primary factor in this calculation. Core Web Vitals data from the Chrome User Experience Report (CrUX) is not available for bymath.net. 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.

bymath.net resolves to the IPv4 address 194.233.168.254 and also supports IPv6 (2a01:7e01::f03c:93ff:feeb:6696), demonstrating modern network infrastructure readiness. The domain has 1 A record(s) configured. The domain name system is managed by 5 name servers: ns1.linode.com, ns2.linode.com, ns3.linode.com, ns4.linode.com, and ns5.linode.com. Having 5 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 bymath.net is handled by Zoho Mail with 3 MX records configured: mx.zoho.com, mx2.zoho.com, and mx3.zoho.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 bymath.net. 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. Our subdomain enumeration scan discovered 1 active subdomains for bymath.net: www.bymath.net. Active subdomains can reveal the organization's infrastructure, including development environments, API endpoints, and third-party service integrations.

The homepage of bymath.net contains 253 words of visible text content. This is a relatively short page — adding more descriptive content could improve search engine visibility. The page is structured with 0 H2 headings, 2 H3 headings, 0 H4 headings. The page includes 1 image. 1 images (100%) 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 0% of images have proper alt text — we recommend adding descriptive alt attributes to all images. The link structure consists of 26 internal links pointing to other pages on the same domain and 0 external links pointing to third-party websites. There are 4 external JavaScript files, 5 CSS stylesheets, and 0 iframes on the page. Notable missing features: XML Sitemap, robots.txt, and Schema.org structured data. Adding these could improve search engine discoverability and rich result eligibility.

The title tag for bymath.net is good at 67 characters: "Вся элементарная математика - Средняя математическая интернет-школа". The length is acceptable, though it may be slightly truncated in some search result displays. The meta description is 313 characters (slightly long): "Математическая школа в интернете. Все разделы программы средней школы по элементарной математике. Арифметика, алгебра, г...". Google typically displays up to 155-160 characters of the meta description in search results. A compelling meta description with a clear call-to-action can significantly improve click-through rates from search results. The meta robots directive is set to all and a favicon is configured.
