The WhoisXML API research team analyzed 7.6+ million domains registered between 1 and 31 January 2025, along with 61.2+ billion domains from our DNS database’s A record full file released in January 2025.
Our research team uncovered:
Let’s cap off 2024 with the Global Domain Activity Report for Q4, this time focusing on registrant behaviors connected to 24.4+ million newly registered domains (NRDs). We also analyzed 3.5+ million indicators of compromise (IoCs) detected in the same period, 697.4+ million mail exchange (MX) resolutions, and 1.5+ billion name server (NS) resolutions.
Our research team leveraged WhoisXML API’s extensive domain, DNS, and threat intelligence to uncover:
The WhoisXML API research team analyzed 7.9+ million domains registered between 1 and 31 December 2024, along with 60.1+ billion domains from our DNS database’s A record full file and 1.3+ million domains detected as indicators of compromise (IoCs) for the month.
Our research team uncovered:
The WhoisXML API research team analyzed 8.2 million domains registered between 1 and 30 November 2024, 59.6 billion domains from our DNS database’s A record full file released in November 2024, and 1.1 million domains detected as indicators of compromise (IoCs) in the same month.
