June 2025: Domain Activity Highlights
WhoisXML API analyzed 9.8+ million domains registered between 1 and 30 June 2025 to identify the most popular registrars, top-level domain (TLD) extensions, and other global domain registration trends.
We also determined the top TLD extensions used by 51.7+ billion domains from our DNS database’s A record full file dated 5 June 2025.
Next, we studied the top TLDs of 1.0+ million domains detected as indicators of compromise (IoCs) this June.
Finally, we summed up our findings and provided links to the threat reports produced using DNS, IP, and domain intelligence sources during the period.
