WhoisXML API analyzed 12.3+ million domains registered between 1 and 30 September 2026 that appeared in Newly Registered Domains to identify the most popular registrars, TLD extensions, and other global domain registration trends. This number rose by 5.9% from 11.6+ million NRDs last month.
We also determined the top TLD extensions used by 3.2+ million domains likely registered with malicious intent from the First Watch Malicious Domains Data Feed in September 2026. This number increased by 8.3% from the previous month.
Next, we studied the top TLD extensions of 1.07+ million confirmed malicious domains from the Threat Intelligence Data Feeds this month, which declined by 2.1% from 1.09+ million in August.
Finally, we summed up our findings and provided links to the threat reports produced using DNS and domain intelligence sources during the period.
