arkdive.com Trust Score & Safety Analysis
🤖 AI Summary
After conducting a thorough safety and legitimacy analysis, arkdive.com receives a trust score of 58/100, 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 DKIM (DomainKeys Identified Mail) providing cryptographic email verification.
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 arkdive.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.

arkdive.com Performance, Speed & Core Web Vitals
🤖 AI Summary
arkdive.com delivers its homepage in 9045ms (server response time), which is considered slow by industry standards. The total page weight is 139 KB, and we detected 425 resource requests loading assets from 23 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: 5 out of 10 CSS files and 15 out of 25 JavaScript files are minified. Minifying the remaining 15 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 arkdive.com produces approximately 0.07g 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 139 KB is the primary factor in this calculation.
Core Web Vitals data from the Chrome User Experience Report (CrUX) is not available for arkdive.com. 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.

arkdive.com DNS Records, Email Authentication & Domain Registration
🤖 AI Summary
arkdive.com resolves to the IPv4 address 118.27.99.220, 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: ns-a1.conoha.io, ns-a2.conoha.io, and ns-a3.conoha.io. 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 arkdive.com is handled by ne.jp with 1 MX records configured: mail57.conoha.ne.jp. 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 (DomainKeys Identified Mail) is configured, adding a cryptographic signature to outgoing emails that receiving servers can verify to confirm the email hasn't been tampered with in transit.
DNSSEC is not enabled for arkdive.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 2 active subdomains for arkdive.com: mail.arkdive.com and www.arkdive.com. Active subdomains can reveal the organization's infrastructure, including development environments, API endpoints, and third-party service integrations.
