DNS (Domain Name System) is the internet's phonebook — it translates domain names like "google.com" into IP addresses that computers use to connect. A DNS lookup queries these records to show you the technical configuration of a domain, including where it points, how email is routed, and what security policies are in place.
These are email authentication DNS records. SPF (Sender Policy Framework) lists which mail servers are authorised to send email for a domain. DKIM (DomainKeys Identified Mail) cryptographically signs emails. DMARC (Domain-based Message Authentication) defines what to do with emails that fail SPF/DKIM. Domains missing these records are easily spoofed — a major phishing red flag.
MX (Mail Exchange) records specify which mail servers receive email for a domain. Checking MX records tells you which email provider a company uses (Google Workspace, Microsoft 365, etc.) and confirms that the domain actually has email configured — a domain with no MX records cannot receive email, which is suspicious if someone claims to be emailing you from it.
DNS records can reveal a lot about a domain's legitimacy. No SPF or DMARC record means the domain can be spoofed easily. An A record pointing to a known malicious IP is a strong red flag. A recently changed NS record may indicate the domain was compromised or transferred. Our DNS lookup checks all of this and flags suspicious patterns automatically.
