Learn what each piece of domain information means and why it matters.

🌐
IP Address
A numerical label assigned to every device connected to a network. It identifies where a website is hosted.
🌐
DNS Records
DNS translates domain names to IP addresses. Records like A, MX, and NS control how your domain works.
📋
WHOIS / RDAP
Public registration data for a domain: who registered it, when, and when it expires.
🔒
SSL Certificate
Encrypts the connection between your browser and the website. A valid SSL means HTTPS works.
📡

Metadata sent by the server with every response. Reveals server software, caching, and security settings.
🏠
Hosting Information
Where the website physically lives: the server, provider, and geographic location.
📧
Mail Security (SPF & DMARC)
Email authentication records that prevent spoofing and phishing from your domain.
🛡️
Security Headers
HTTP headers that protect visitors from common web attacks like clickjacking and XSS.
📊
HTTP Status Code
A three-digit code indicating whether a request succeeded, redirected, or failed.
⏰
Domain Expiry
When the domain registration expires. If not renewed, the domain becomes available to others.
⏰
SSL Certificate Expiry
