80blo.net

We performed a comprehensive analysis of 80blo.net on 2026-06-28. The website returned an HTTP 200 status code with a server response time of 10286ms. The page is served over HTTP/2 protocol with Gzip compression enabled, achieving approximately 60.0% size reduction. The total page weight is 109 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: Permissions-Policy. However, the site is missing Content-Security-Policy, Strict-Transport-Security (HSTS), X-Frame-Options, X-Content-Type-Options, and Referrer-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 80blo.net. The detected stack includes WordPress, Google Analytics 4, Google AdSense, StackPath, Google Fonts, jQuery, and Font Awesome. Based on our comprehensive analysis of domain age, SSL configuration, email authentication, security headers, and blacklist status, 80blo.net receives an overall trust score of 56/100, classified as "Caution Advised".

After conducting a thorough safety and legitimacy analysis, 80blo.net receives a trust score of 56/100, 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 a well-established domain registered for over 8.9 years, indicating long-term commitment and legitimacy. 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, 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 80blo.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. The domain is registered through XServer, Inc., with a registration date of 2017-08-14 and expiration date of 2026-08-14.

80blo.net delivers its homepage in 10286ms (server response time), which is considered slow by industry standards. The total page weight is 109 KB, and we detected 234 resource requests loading assets from 8 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: 6 out of 11 CSS files and 10 out of 16 JavaScript files are minified. Minifying the remaining 11 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 80blo.net 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 109 KB is the primary factor in this calculation. Core Web Vitals data from the Chrome User Experience Report (CrUX) is not available for 80blo.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.

80blo.net resolves to the IPv4 address 202.254.234.105, 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 5 name servers: ns1.xserver.jp, ns2.xserver.jp, ns3.xserver.jp, ns4.xserver.jp, and ns5.xserver.jp. 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 80blo.net is handled by 80blo.net with 1 MX records configured: 80blo.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 not enabled for 80blo.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. The domain is registered through XServer, Inc.. It was first registered on 2017-08-14 and is set to expire on 2026-08-14, making it 8.9 years old. Our subdomain enumeration scan discovered 25 active subdomains for 80blo.net: admin.80blo.net, api.80blo.net, app.80blo.net, apps.80blo.net, blog.80blo.net, cdn.80blo.net, community.80blo.net, and dev.80blo.net. Plus 17 additional subdomains. Active subdomains can reveal the organization's infrastructure, including development environments, API endpoints, and third-party service integrations.

The homepage of 80blo.net contains 493 words of visible text content. This is a moderate amount of content. The page is structured with 0 H2 headings, 0 H3 headings, 3 H4 headings. The page includes 23 images. 4 images (17%) 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 83% of images have proper alt text — we recommend adding descriptive alt attributes to all images. The link structure consists of 164 internal links pointing to other pages on the same domain and 1 external link pointing to third-party websites. The high number of internal links suggests a well-interconnected site structure, which helps search engines discover and crawl all pages efficiently.

The site implements the following web standards and features: XML Sitemap (helps search engines discover all pages), Schema.org structured data (BreadcrumbList, CollectionPage, ImageObject, ListItem, Person, and WebSite), and RSS feed for content syndication. Notable missing features: robots.txt. Adding these could improve search engine discoverability and rich result eligibility.
