                "Public Interest Registry provides this RDAP service for informational purposes only, and to assist persons in obtaining information about or related to a domain name registration record. Public Interest Registry does not guarantee its accuracy. Users accessing the Public Interest Registry RDAP service agree to use the data only for lawful purposes, and under no circumstances may this data be used to: a) allow, enable, or otherwise support the transmission by e-mail, telephone, or facsimile of mass unsolicited, commercial advertising or solicitations to entities other than the registrar's own existing customers and b) enable high volume, automated, electronic processes that send queries or data to the systems of Public Interest Registry or any ICANN-accredited registrar, except as reasonably necessary to register domain names or modify existing registrations. When using the Public Interest Registry RDAP service, please consider the following: the RDAP service is not a replacement for standard EPP commands to the SRS service. RDAP is not considered authoritative for registered domain objects. The RDAP service may be scheduled for downtime during production or OT&E maintenance periods. Queries to the RDAP services are throttled. If too many queries are received from a single IP address within a specified time, the service will begin to reject further queries for a period of time to prevent disruption of RDAP service access. Abuse of the RDAP system through data mining is mitigated by detecting and limiting bulk query access from single sources. Where applicable, the presence of a [Non-Public Data] tag indicates that such data is not made publicly available due to applicable data privacy laws or requirements. Should you wish to contact the registrant, please refer to the RDAP records available through the registrar URL listed above. Access to non-public data may be provided, upon request, where it can be reasonably confirmed that the requester holds a specific legitimate interest and a proper legal basis for accessing the withheld data. Access to this data can be requested by submitting a request to WHOISrequest@pir.org. Public Interest Registry Inc. reserves the right to modify these terms at any time.

Understanding Diagnostic Terms for sdmpscbse.org

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.
