DNS Lookup Tool
Use the Free Cybersecurity Tools from ZeroThrex to view DNS records and verify domain authenticity. Check A, MX, TXT, NS, and CNAME records to detect misconfigurations or phishing threats.
DNS Record Types Explained
A Record (Address Record)
The A record maps your domain name to its IPv4 address. It’s what tells browsers where your website is hosted on the internet.
MX Record (Mail Exchange)
The MX record defines the mail servers responsible for receiving emails for your domain. It ensures that messages sent to your address reach the correct mail server.
TXT Record (Text Record)
The TXT record stores custom text data. Commonly used for SPF and DKIM configurations, it helps verify domain ownership and protect against email spoofing.
NS Record (Name Server)
The NS record identifies which name servers are authoritative for your domain. These servers hold all the DNS records that define your domain’s behavior online.
CNAME Record (Canonical Name)
The CNAME record creates an alias that points one domain to another. It’s often used for subdomains like www to link them with the main domain.
