DNS (Domain Name System)
The Domain Name System translates human-readable domain names (like ismalicious.com) into IP addresses. DNS data is a rich source of threat intelligence — malicious domains, fast-flux networks, DNS tunneling, and typosquatting are all detectable via DNS analysis.
Frequently Asked Questions
What is DNS (Domain Name System)?
The Domain Name System translates human-readable domain names (like ismalicious.com) into IP addresses. DNS data is a rich source of threat intelligence — malicious domains, fast-flux networks, DNS tunneling, and typosquatting are all detectable via DNS analysis.
How is DNS (Domain Name System) related to DNS History?
DNS (Domain Name System) and DNS History are both key concepts in threat intelligence. DNS history is a record of historical DNS resolution data for a domain — including all IP addresses it has ever resolved to, when changes occurred, and what nameservers have been used. It is used in threat investigations to trace infrastructure reuse and identify related malicious domains.

Domain Reputation
Domain reputation is a classification of a domain based on its history of malicious activity, registration patterns, and content. Factors include age, registrar, phishing/malware associations, WHOIS data, and appearance on threat feeds.
NRD (Newly Registered Domain)
A Newly Registered Domain is a domain registered within the past 30–90 days. NRDs are a key risk signal because the vast majority of phishing campaigns, malware distribution, and spam infrastructure uses freshly registered domains to evade blocklists.
