thegioingoaingu.com

We performed a comprehensive analysis of thegioingoaingu.com on 2026-06-28. The website returned an HTTP 200 status code with a server response time of 18427ms. The page is served over HTTP/2 protocol with Gzip compression enabled, achieving approximately 60.0% size reduction. The total page weight is 211 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 0/100 (poor). No security headers are configured, which is a significant security concern. However, the site is missing Content-Security-Policy, Strict-Transport-Security (HSTS), X-Frame-Options, 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 4 technologies across 4 categories powering thegioingoaingu.com. The detected stack includes Google Analytics 4, Google Tag Manager, Meta Pixel, and jQuery 1.8.3.. Based on our comprehensive analysis of domain age, SSL configuration, email authentication, security headers, and blacklist status, thegioingoaingu.com receives an overall trust score of 56/100, classified as "Caution Advised".

After conducting a thorough safety and legitimacy analysis, thegioingoaingu.com 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 and SPF (Sender Policy Framework) email authentication preventing email spoofing. 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 thegioingoaingu.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.

Our technology detection engine scanned thegioingoaingu.com and identified 4 distinct technologies across 4 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 thegioingoaingu.com. Tag Manager: Google Tag Manager — manages marketing and analytics tags without code changes for thegioingoaingu.com. Advertising: Meta Pixel — handles advertising pixel tracking and conversion measurement for thegioingoaingu.com. JavaScript Library: jQuery (version 1.8.3.) — provides utility functions and DOM manipulation for thegioingoaingu.com. We also extracted the following tracking identifiers: Google Tag Manager container GTM-KHJJ7PW and Meta (Facebook) Pixel ID 1577010608991498. These IDs can be used to identify other websites operated by the same organization.

thegioingoaingu.com resolves to the IPv4 address 103.131.74.32, 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.pavietnam.vn, ns2.pavietnam.vn, and nsbak.pavietnam.net. 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 thegioingoaingu.com is handled by thegioingoaingu.com with 1 MX records configured: mail.thegioingoaingu.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 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 thegioingoaingu.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. Our subdomain enumeration scan discovered 25 active subdomains for thegioingoaingu.com: admin.thegioingoaingu.com, api.thegioingoaingu.com, app.thegioingoaingu.com, apps.thegioingoaingu.com, blog.thegioingoaingu.com, cdn.thegioingoaingu.com, community.thegioingoaingu.com, and dev.thegioingoaingu.com. Plus 17 additional subdomains. Active subdomains can reveal the organization's infrastructure, including development environments, API endpoints, and third-party service integrations.

The title tag for thegioingoaingu.com is good at 67 characters: "Học tiếng Trung với trung tâm tiếng Trung đông học viên nhất Hà Nội". The length is acceptable, though it may be slightly truncated in some search result displays. The meta description is 137 characters (well-optimized): "Học tiếng Trung tại trung tâm tiếng Trung đông học viên nhất tại Hà Nội. Học tiếng Trung trực tiếp với vua tiếng Trung y...". Google typically displays up to 155-160 characters of the meta description in search results. A compelling meta description with a clear call-to-action can significantly improve click-through rates from search results. The canonical url is correctly set to https://thegioingoaingu.com/, preventing duplicate content issues, the page language is declared as vi, and a favicon is configured. Open Graph meta tags are configured with 4/4 recommended fields: OG title ("Học tiếng Trung với trung tâm tiếng Trung đông học viên nhất..."), OG description, OG image (social sharing thumbnail), OG type (article). These tags control how the page appears when shared on Facebook, LinkedIn, and other social media platforms that support the Open Graph protocol. The meta keywords tag contains 5 terms including Học tiếng Trung, trung tâm tiếng Trung, hoc tieng trung, trung tam tieng trung, and học tiếng trung giao tiếp. Note: Google has officially confirmed that it does not use the meta keywords tag as a ranking signal. However, some other search engines (Bing, Yandex) may still reference it.
