Understanding Diagnostic Terms for rcfl.com.hk
Domain Status (EPP)
EPP status codes (e.g., clientTransferProhibited, active) indicating if a domain is locked against unauthorized transfer, pending renewal, or active.
Registrar Information
The authorized or accredited organization managing the domain reservation and authoritative registry delegation.
Nameservers (NS)
Authoritative servers that translate domain names into IP addresses and direct web visitors and mail traffic globally.
A & AAAA Records
Primary address records mapping your domain name directly to standard IPv4 (e.g., 192.0.2.1) and newer IPv6 server network addresses.
MX (Mail Exchange)
Priority-ranked records pointing inbound emails to designated mail server hosts (e.g., Google Workspace, Microsoft 365, Zoho).
SPF & DMARC Security
Email authentication standards that verify authorized sender IPs (SPF) and instruct receiving servers how to enforce security policies (DMARC).
DKIM Signatures
Cryptographic public key in DNS used by receiving mail servers to verify digital signatures on your emails, ensuring messages were not tampered with.
SSL Certificate & Chain
Establishes encrypted HTTPS connections and authenticates domain ownership via an intermediate certificate authority chain.
Hosting Provider & ASN
The physical server infrastructure where website files reside and the autonomous system network (ASN) routing global traffic.
Reverse DNS (PTR)
Pointer (PTR) records that map a server's IP address back to its canonical hostname, verifying server identity and preventing email spam rejection.
HTTP Security Headers
Directives like HSTS, CSP, and X-Frame-Options instructed by the server to protect browser visitors against XSS, clickjacking, and packet sniffing.
⚠️ Report Limitations & Data Sources
- Data Currency: This report uses cached registry and DNS data (freshened within 4 hours) for high-speed resolution. Click "🔄 Refresh Live" to query directly against authoritative registries.
- DNS Resolution & Propagation: Records are queried via Google Public DNS-over-HTTPS. Global DNS propagation may take up to 24–48 hours across different regional ISP resolvers during recent DNS record changes.
- Completeness & Scope: This diagnostic tool analyzes standard authoritative records (A, AAAA, MX, NS, TXT, CNAME, SOA). It does not perform invasive brute-force subdomain scans or unauthenticated DNS zone transfers.
- Email Deliverability & Reputation: The security analysis (SPF, DKIM, DMARC, and Port 25 SMTP handshake) reflects public DNS policies and inbound connection states. Recipient spam filters evaluate internal headers that cannot be checked from outside.
- Reverse Proxies & CDNs: If a website is behind Cloudflare, Fastly, or another CDN/reverse proxy, the detected IP, web server software, and SSL edge certificate reflect the proxy tier.
