Understanding Your Report for penzu.com
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.
