es.net

We performed a comprehensive analysis of es.net on 2026-06-29. The website returned an HTTP 200 status code with a server response time of 21795ms. The page is served over HTTP/2 protocol with Gzip compression enabled, achieving approximately 60.0% size reduction. The total page weight is 35 KB, and the site is served behind a CDN (Content Delivery Network). The website uses a secure HTTPS connection with a valid SSL certificate issued by Internet2 (DV type). The connection is encrypted using TLS 1.3 with the TLS_AES_256_GCM_SHA384 cipher suite and sha256WithRSAEncryption signature algorithm. The certificate covers 1 domain(s) (Subject Alternative Names) and expires on 2027-01-02, which is 187 days from now. The security headers analysis reveals a score of 35/100 (below average). The following security headers are properly configured: Strict-Transport-Security (HSTS) and X-Frame-Options. However, the site is missing Content-Security-Policy, 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 2 technologies across 2 categories powering es.net. The detected stack includes Google Analytics 4 and jQuery 1.7.2.. Based on our comprehensive analysis of domain age, SSL configuration, email authentication, security headers, and blacklist status, es.net receives an overall trust score of 77/100, classified as "Likely Safe".

After conducting a thorough safety and legitimacy analysis, es.net receives a trust score of 77/100, 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, HSTS (HTTP Strict Transport Security) enforcement preventing protocol downgrade attacks, a valid SSL certificate issued by Internet2 with 187 days until expiration, SPF (Sender Policy Framework) email authentication preventing email spoofing, DMARC email authentication with a none policy, 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, 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 es.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 es.net and identified 2 distinct technologies across 2 categories. This analysis is performed by examining HTTP response headers, HTML source code patterns, JavaScript library fingerprints, CSS framework signatures, and DNS records. Analytics: Google Analytics 4 — tracks visitor behavior and provides traffic insights for es.net. JavaScript Library: jQuery (version 1.7.2.) — provides utility functions and DOM manipulation for es.net. We also extracted the following tracking identifiers: Google Analytics 4 Measurement ID G-9Y9H16804B. These IDs can be used to identify other websites operated by the same organization.

es.net delivers its homepage in 21795ms (server response time), which is considered slow by industry standards. The total page weight is 35 KB, and we detected 119 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: 0 out of 4 CSS files and 9 out of 18 JavaScript files are minified. Minifying the remaining 13 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. The site is served through a Content Delivery Network (CDN), which caches static assets at edge servers around the world. This means visitors from different geographic regions receive content from the nearest edge server, significantly reducing latency. CDN usage is particularly important for websites with a global audience, as it can reduce page load times by 40-60% for distant visitors. From an environmental perspective, each page view of es.net produces approximately 0.02g 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 35 KB is the primary factor in this calculation. Core Web Vitals data from the Chrome User Experience Report (CrUX) is not available for es.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.

es.net resolves to the IPv4 address 198.128.136.135 and also supports IPv6 (2001:400:210:87::85), demonstrating modern network infrastructure readiness. The domain has 1 A record(s) configured. The domain name system is managed by 2 name servers: adns1.es.net and adns2.es.net. 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 es.net is handled by es.net with 2 MX records configured: nmx1.es.net and mail.es.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 (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 enabled for es.net, 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 es.net contains 383 words of visible text content. This is a moderate amount of content. The page is structured with 6 H2 headings, 0 H3 headings, 0 H4 headings.
