DMARC Record Validation i

Record Breakdown

Tag	Value	Description

Validation Summary

DMARC Record Published	Pass A DMARC record was found.
Syntax Check	Fail The record must begin with "v=DMARC1".
Policy Enforcement	Warning The policy is "p=none", which is for monitoring only and does not protect against spoofing.
Aggregate Reporting	Warning No "rua" tag was found. You will not receive summary reports.

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.

It is highly recommended to add an "rua" tag (e.g., "rua=mailto:dmarc-reports@yourdomain.com") to monitor email traffic and ensure legitimate emails are not failing checks.

Understanding Your Report for semanticweb.cs.vu.nl

Domain Status

Also known as EPP status codes, these indicate the state of the domain. Common statuses include 'clientTransferProhibited' (locked) or 'active' (ready to use).

Registrar Information

The registrar is the accredited organization (like GoDaddy, Namecheap, or Google Domains) where the domain name was purchased and is managed.

Registrant Contact

The individual or organization that legally owns the domain. This information is often redacted for privacy compliance (GDPR).

Nameservers

Servers that act as a directory for your domain. They translate your domain name into IP addresses, telling the internet where to find your website and email services.

NS Records

Name Server records specify which nameservers are authoritative for your domain. Changing these allows you to move DNS management to a different provider.

A Records

Address Records map a domain name directly to an IPv4 address (e.g., 192.0.2.1). This is the primary record used to point a domain to a web server.

AAAA Records

IPv6 Address Records map a domain name to an IPv6 address (e.g., 2001:0db8...). They serve the same purpose as A records but for the newer internet protocol.

WWW Records

Usually a CNAME or A record that ensures 'www.yourdomain.com' loads the same content as the root domain 'yourdomain.com'.

MX Records

Mail Exchange records direct emails sent to your domain to the correct mail servers. Without valid MX records, you cannot receive email.

TXT Records

Text records allow admins to store text notes in the DNS. They are primarily used for domain verification and email security protocols like SPF and DKIM.

SPF Records

Sender Policy Framework is a security record listing the IP addresses and servers authorized to send email on behalf of your domain to prevent spoofing.

DMARC Records

Domain-based Message Authentication, Reporting, and Conformance uses SPF and DKIM to determine email authenticity and instructs receivers how to handle failed checks.

DKIM Records

DomainKeys Identified Mail stores a public key in the DNS. Receivers use this to verify the digital signature on your emails, ensuring they haven't been tampered with.

HTTP Status

A 3-digit code returned by the server indicating the result of a request (e.g., 200 OK, 301 Redirect, 404 Not Found, 500 Server Error).

Hosting Provider

The company providing the physical or virtual servers where your website's files, databases, and content are stored and served to the internet.

Web Server

The software (like Apache, Nginx, or LiteSpeed) running on the hosting server that handles incoming requests and delivers web pages to visitors.

Control Panel

The interface provided by your host (e.g., cPanel, Plesk, DirectAdmin) to manage your website files, databases, email accounts, and settings.

Technology Profile

Detects the underlying software stack used by the website, including Content Management Systems (CMS), JavaScript frameworks, programming languages, and analytics tools.

Report Limitations & Data Sources

Data Currency: This report may use cached data (up to 4 hours) for speed. Use the "Refresh" button to force a live lookup.
DNS Propagation: Records are queried via Google Public DNS. Recently changed records might not be visible immediately due to global propagation delays.
Completeness: This tool checks for specific, common DNS records (A, MX, TXT, etc.). It does not perform a full zone transfer or exhaustive subdomain enumeration.
Security Posture: The security analysis (SPF/DMARC) is based on public DNS availability. It cannot verify internal mail server configurations, firewalls, or email filtering rules.
