Global Domain Activity Report: Q3 2025

The latter half of 2025 brought to light new global domain activity trends aided by the Global Domain Activity Report for Q3 focusing on registrant behaviors connected to 25.7+ million newly registered domains (NRDs). We also analyzed 2.1+ billion mail exchange (MX) resolutions, 4.2+ billion name server (NS) resolutions, and 3.2+ million indicators of compromise (IoCs) detected in the same period.

Our research team leveraged WhoisXML API’s extensive domain, DNS, and threat intelligence to uncover:

  • The top gTLD and ccTLD extensions of the new domains added in Q3 2025 and the IoCs detected in the period
  • The most popular NRD registrars
  • The top MX domains and their providers
  • The top MX fully qualified domain names (FQDNs)
  • The top NS domains and their providers
  • The top NS FQDNs
  • The top IoC TLDs
