y-ml.com

We performed a comprehensive analysis of y-ml.com on 2026-07-07. The website returned an HTTP 200 status code with a server response time of 16133ms. The page is served over HTTP/1.1 protocol, however no compression (Gzip or Brotli) is enabled, which means the page is transferred at its full uncompressed size. The total page weight is 100 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 15/100 (poor). The following security headers are properly configured: X-Frame-Options. However, the site is missing Content-Security-Policy, Strict-Transport-Security (HSTS), 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 8 technologies across 7 categories powering y-ml.com. The detected stack includes WordPress, Google Analytics 4, Microsoft Clarity, Google Tag Manager, Meta Pixel, StackPath, jQuery 1.4.2., and Font Awesome. Based on our comprehensive analysis of domain age, SSL configuration, email authentication, security headers, and blacklist status, y-ml.com receives an overall trust score of 59/100, classified as "Caution Advised".

After conducting a thorough safety and legitimacy analysis, y-ml.com receives a trust score of 59/100, which places it in the "Caution Advised" 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: the absence of a Content-Security-Policy header, which leaves the site more vulnerable to cross-site scripting (XSS) attacks, 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 y-ml.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.

JavaScript Library: jQuery (version 1.4.2.) — provides utility functions and DOM manipulation for y-ml.com. Icon Set: Font Awesome — provides additional functionality for y-ml.com. We also extracted the following tracking identifiers: Google Tag Manager container GTM-T7QG2KW. These IDs can be used to identify other websites operated by the same organization.

y-ml.com delivers its homepage in 16133ms (server response time), which is considered slow by industry standards. The total page weight is 100 KB, and we detected 261 resource requests loading assets from 25 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. No compression is currently enabled on y-ml.com. Enabling Brotli or Gzip compression could reduce page size by 60-80% for text-based assets (HTML, CSS, JavaScript), significantly improving load times and reducing bandwidth costs. This is one of the simplest and most impactful performance optimizations available. Asset minification status: 1 out of 4 CSS files and 2 out of 11 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 y-ml.com produces approximately 0.05g 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 100 KB is the primary factor in this calculation. Core Web Vitals data from the Chrome User Experience Report (CrUX) is not available for y-ml.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.

y-ml.com resolves to the IPv4 address 180.131.138.179, 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 3 name servers: ns1.y-ml.com, ns2.y-ml.com, and slave1.igreks.co.jp. Having 3 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 y-ml.com is handled by y-ml.com with 1 MX records configured: y-ml.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 y-ml.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 y-ml.com contains 393 words of visible text content. This is a moderate amount of content. The page is structured with 15 H2 headings, 11 H3 headings, 1 H4 headings. The page includes 60 images. 8 images (13%) 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 87% of images have proper alt text — we recommend adding descriptive alt attributes to all images. The link structure consists of 96 internal links pointing to other pages on the same domain and 13 external links pointing to third-party websites. There are 11 external JavaScript files, 4 CSS stylesheets, and 2 iframes on the page. The site implements the following web standards and features: Schema.org structured data (ContactPoint, Organization, PaymentMethod, Place, PostalAddress, QuantitativeValue, SoftwareApplication, Thing, WebSite, and offer) and RSS feed for content syndication. Notable missing features: XML Sitemap and robots.txt. Adding these could improve search engine discoverability and rich result eligibility.
