planetarium-nuernberg.de

We performed a comprehensive analysis of planetarium-nuernberg.de on 2026-07-04. The website returned an HTTP 200 status code with a server response time of 31629ms. The page is served over HTTP/2 protocol with Gzip compression enabled, achieving approximately 60.0% size reduction. The total page weight is 118 KB. The website uses a secure HTTPS connection with a valid SSL certificate issued by Sectigo Limited (OV 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 2 domain(s) (Subject Alternative Names) and expires on 2026-10-17, which is 105 days from now. The security headers analysis reveals a score of 15/100 (poor). The following security headers are properly configured: X-Content-Type-Options. However, the site is missing Content-Security-Policy, Strict-Transport-Security (HSTS), X-Frame-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 1 technologies across 1 categories powering planetarium-nuernberg.de. The detected stack includes Matomo. Based on our comprehensive analysis of domain age, SSL configuration, email authentication, security headers, and blacklist status, planetarium-nuernberg.de receives an overall trust score of 65/100, classified as "Likely Safe".

After conducting a thorough safety and legitimacy analysis, planetarium-nuernberg.de 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 Sectigo Limited with 105 days until expiration, and DMARC email authentication with a reject policy — the strongest available setting. 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 planetarium-nuernberg.de 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 planetarium-nuernberg.de and identified 1 distinct technologies across 1 categories. This analysis is performed by examining HTTP response headers, HTML source code patterns, JavaScript library fingerprints, CSS framework signatures, and DNS records. Analytics: Matomo — tracks visitor behavior and provides traffic insights for planetarium-nuernberg.de.

planetarium-nuernberg.de delivers its homepage in 31629ms (server response time), which is considered slow by industry standards. The total page weight is 118 KB, and we detected 73 resource requests loading assets from 5 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 2 CSS files and 0 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 planetarium-nuernberg.de produces approximately 0.06g 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 118 KB is the primary factor in this calculation. Core Web Vitals data from the Chrome User Experience Report (CrUX) is not available for planetarium-nuernberg.de. 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.

planetarium-nuernberg.de resolves to the IPv4 address 81.169.145.70 and also supports IPv6 (2a01:238:20a:202:1070::), demonstrating modern network infrastructure readiness. The domain has 1 A record(s) configured. The domain name system is managed by 2 name servers: docks18.rzone.de and shades07.rzone.de. 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 planetarium-nuernberg.de is handled by rzone.de with 1 MX records configured: smtpin.rzone.de. Multiple MX records provide failover redundancy — if the primary mail server is unavailable, email will be routed to the next available server. SPF is not configured, meaning any server could potentially send emails pretending to be from this domain. This is a significant email security concern. DMARC (Domain-based Message Authentication, Reporting and Conformance) is configured with a reject policy — the strongest setting, instructing receiving servers to reject unauthorized emails entirely. 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 planetarium-nuernberg.de. 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.
