Record Breakdown

Prefix	Mechanism	Value	Description
+	`v`	spf1	The SPF record version.
+	`mx`		Match if the sender's IP is one of the domain's MX records.
+	`a`	mx100.ucozmail.com	Match if the sender's IP is one of the domain's A records.
+	`include`	rsndr.ru	The specified domain is searched for a match.
~	`all`		Always matches. This should be the last mechanism.

Validation Summary

SPF Record Published	Pass An SPF record was found.
Multiple SPF Records	Pass Only one SPF record was found.
Included Lookups	Pass The number of DNS lookups (3) is within the limit of 10.
Type PTR Check	Pass The deprecated PTR mechanism was not found.

Tag Breakdown

Tag	Value	Description
`v`	DMARC1	Version: Must be "DMARC1".
`p`	none	Policy: The action to take for failed emails (none, quarantine, reject).

Validation Summary

DMARC Record Published	Pass A DMARC record was found.
Syntax Check	Pass The record has a valid version tag.
Policy Enforcement	Warning The policy is "p=none", which is for monitoring only and does not protect against spoofing.
Aggregate Reporting	Pass An address for aggregate reports was found.

Optimization Suggestions

After monitoring your aggregate reports to ensure legitimate email sources are aligned, you should move to a "p=quarantine" or "p=reject" policy to protect your domain.

Understanding Diagnostic Terms for u.to

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.
