niengkhongnhorang.vn

We performed a comprehensive analysis of niengkhongnhorang.vn on 2026-07-03. The website returned an HTTP 200 status code with a server response time of 12018ms. The page is served over HTTP/2 protocol with Gzip compression enabled, achieving approximately 60.0% size reduction. The total page weight is 172 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 2027-03-05, which is 245 days from now. The security headers analysis reveals a score of 45/100 (below average). The following security headers are properly configured: X-Frame-Options, X-Content-Type-Options, and Referrer-Policy. However, the site is missing Content-Security-Policy, Strict-Transport-Security (HSTS), 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 7 technologies across 7 categories powering niengkhongnhorang.vn. The detected stack includes WordPress, Google Analytics 4, Google Tag Manager, Meta Pixel, Google Fonts, YouTube Embed, and jQuery. Based on our comprehensive analysis of domain age, SSL configuration, email authentication, security headers, and blacklist status, niengkhongnhorang.vn receives an overall trust score of 70/100, classified as "Likely Safe".

After conducting a thorough safety and legitimacy analysis, niengkhongnhorang.vn receives a trust score of 70/100, 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 245 days until expiration, SPF (Sender Policy Framework) email authentication preventing email spoofing, 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 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 niengkhongnhorang.vn 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.

niengkhongnhorang.vn delivers its homepage in 12018ms (server response time), which is considered slow by industry standards. The total page weight is 172 KB, and we detected 143 resource requests loading assets from 7 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 0 CSS files and 1 out of 1 JavaScript files are minified. All assets are properly minified, reducing file sizes by removing whitespace, comments, and shortening variable names. Minification is a best practice that reduces download sizes without affecting functionality. From an environmental perspective, each page view of niengkhongnhorang.vn produces approximately 0.08g 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 172 KB is the primary factor in this calculation. Core Web Vitals data from the Chrome User Experience Report (CrUX) is not available for niengkhongnhorang.vn. 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.

niengkhongnhorang.vn resolves to the IPv4 address 45.117.177.27, 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 2 name servers: ns1.matbao.vn and ns2.matbao.vn. 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 niengkhongnhorang.vn is handled by niengkhongnhorang.vn with 1 MX records configured: mail.niengkhongnhorang.vn. 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 enabled for niengkhongnhorang.vn, 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.
