a1coffee.net Trust Score & Safety Analysis
🤖 AI Summary
After conducting a thorough safety and legitimacy analysis, a1coffee.net receives a trust score of 73/100, 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, HSTS (HTTP Strict Transport Security) enforcement preventing protocol downgrade attacks, SPF (Sender Policy Framework) email authentication preventing email spoofing, and DMARC email authentication with a none policy.
Areas of concern include: 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 a1coffee.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.

a1coffee.net Performance, Speed & Core Web Vitals
🤖 AI Summary
a1coffee.net delivers its homepage in 5199ms (server response time), which is considered slow by industry standards. The total page weight is 662 KB, and we detected 362 resource requests loading assets from 13 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: 2 out of 21 CSS files and 3 out of 41 JavaScript files are minified. Minifying the remaining 57 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.
The site is served through a Content Delivery Network (CDN), which caches static assets at edge servers around the world. This means visitors from different geographic regions receive content from the nearest edge server, significantly reducing latency. CDN usage is particularly important for websites with a global audience, as it can reduce page load times by 40-60% for distant visitors.
From an environmental perspective, each page view of a1coffee.net produces approximately 0.32g of CO₂, earning a carbon rating of C. This is an average carbon footprint. Optimizing images and reducing unnecessary scripts could further improve this score. For reference, the average web page produces about 0.5g of CO₂ per page view. The page weight of 662 KB is the primary factor in this calculation.
Core Web Vitals data from the Chrome User Experience Report (CrUX) is not available for a1coffee.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.

a1coffee.net DNS Records, Email Authentication & Domain Registration
🤖 AI Summary
a1coffee.net resolves to the IPv4 address 23.227.38.65, 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: buck.ns.cloudflare.com and susan.ns.cloudflare.com. 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 a1coffee.net is handled by a1coffee.net with 3 MX records configured: mail.a1coffee.net, mailgate1.a1coffee.net, and mailgate2.a1coffee.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 (Domain-based Message Authentication, Reporting and Conformance) is configured with a none policy — a monitoring-only setting that doesn't enforce any action on unauthorized emails. 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 a1coffee.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.
Our subdomain enumeration scan discovered 2 active subdomains for a1coffee.net: mail.a1coffee.net and www.a1coffee.net. Active subdomains can reveal the organization's infrastructure, including development environments, API endpoints, and third-party service integrations.
