WhoisXML API analyzed 8.3+ million domains registered between 1 and 31 July 2025, 49.3+ billion domains from our DNS database’s A record full file dated 3 July 2025, and 1.1+ million IoCs detected in the same period.
Our research team uncovered:
Half of 2025 is over. It’s time to look at the global domain activity trends again aided by the Global Domain Activity Report for Q2 focusing on registrant behaviors connected to 26.0+ million newly registered domains (NRDs). We also analyzed 1.9+ billion mail exchange (MX) resolutions, 3.8+ billion name server (NS) resolutions, and 3.9+ million indicators of compromise (IoCs) detected in the same period.
