How can you use Passive DNS data?

Searching real time and historic Passive DNS data enables you to undertake various research tasks:

  • Investigate suspicious domains by revealing their current and historical IP address associations.
  • Research IP addresses or domains that have raised suspicion and see if it’s a single entity or multilayered operation.
  • Reveal the health of your hosting network by discovering what other domains and organizations are associated with the IP blocks and nameservers used by your hosting provider.
  • Analyze lookalike domains to evaluate their threat potential.
  • Detect infringement of your copyright and brands by detecting spoofed domains.
  • Uncover previously unknown areas of your network by searching for subnets of domains.
