These refer to domains that have consistently resolved through DNS over a long period. Long-lived DNS activity often indicates legitimate, mature, and stable infrastructure, since malicious domains typically have short lifespans due to rapid detection and takedowns.
The questions every analyst asks before acting on this signal.
These refer to domains that have consistently resolved through DNS over a long period. Long-lived DNS activity often indicates legitimate, mature, and stable infrastructure, since malicious domains typically have short lifespans due to rapid detection and takedowns.
It means the domain has continuously resolved to the same IP address for an extended duration. Such stability is typical of corporate or cloud-based infrastructure, whereas malicious domains frequently change IPs to evade detection, a technique known as 'fast-flux'.
Thresholds vary depending on data telemetry and observation periods. Typically, domains active for over 6, 12 months are considered 'Long-Lived', while those continuously resolving for more than 1 year are deemed 'Well-Established'. These metrics help analysts assess domain trustworthiness over time.
