Benefits of our reverse DNS database

  • Comprehensive, coherent, and covering more TLDs than any other

    We offer the most recently updated domain database with every domain name linked to its IP address and host. Get downloads for all major gTLDs.

  • Get access to exhaustive and properly parsed data

    Obtain an up-to-date DNS database archive download as Comma Separated Values (.CSV) files or database dumps (MYSQL) to stay on top of the latest changes — suspicious or not — to DNS records.

  • Transform threat intelligence into actionable prevention and mitigation steps

    Manually parsing raw passive DNS data can be a tedious and error-prone job. With DNS Database Download, users can skip the legwork and readily turn feeds into effective defensive measures.

Practical usage

Threat hunting and defense

Threat hunting and defense

  • Track down suspicious cyber resources (hostnames, IP addresses, command-and-control [C&C] servers) and get the latest malware, phishing, or other threat information.
  • Detect patterns of malicious activity and identify phishing or other targeted attacks.
  • Discover associations among threat actors based on domain, IP, and DNS record associations to track and block their activity.
  • Conduct fact-based risk profile audits of domain names, IP addresses, and other digital assets.
  • Reveal all domains using the same host, DNS server, MX server or other infrastructure as an existing known malicious domain/threat actor.
  • Uncover all IPs a bad actor is using to hide malicious activity and avoid takedowns.
  • Conduct third-party audits of DNS/MX configurations.
  • Research fraudulent anomalous activities and get the intel and context needed to prevent them from reoccurring in the future.

Cybercrime investigation

Cybercriminals may use the same infrastructure resources and leave similar signatures and traces behind. DNS history allows you to follow those leads.

Cyber forensics analysis

Discover DNS record changes and see how threat incidents correlate. Accelerate incident response and post-breach analysis with context using current and historic domain and IP information.

Cybersecurity and anti-malware solution enhancement

Identify spam, dangerous websites, intrusions, and other web-related misbehavior.

SIEM and SOAR data enrichment

Obtain DNS intelligence for a variety of security information and event management (SIEM); security orchestration, automation, and response (SOAR); and threat intelligence (TI) platforms. Power next-generation firewalls (NGFWs) with better DNS intelligence data points.

Brand protection and market intelligence gathering

Brand protection and market intelligence gathering

  • Monitor your brand trademarks or copyrights and be notified of infringement when they are used on fraudulent domains.
  • Identify associations between IP addresses, hostnames, and organizations.
  • Gain insights into domains.
