We are excited to introduce DNS Chronicle API, the latest addition to our passive DNS offerings. This API release enables use cases such as proactive threat detection and attack surface discovery by providing visibility into the complete DNS history of a domain or an IP address.

With DNS Chronicle API, users can perform two types of passive DNS queries, namely:

• Forward search: Using any FQDN as a search string, users can retrieve its historical A and AAAA records.

• Reverse search: Users can obtain a list of all the FQDNs associated with a given IP address.

The WhoisXML API research team analyzed more than 7.1 million domains registered between 1 and 30 September 2024 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 the more than 60.1 billion domains from our DNS database’s A record full file released in the same month.

Next, we studied the top TLDs and associated threat types of more than 1.0 million domains detected as indicators of compromise (IoCs) in September.

Finally, we summed up our findings and provided links to the threat reports produced using DNS, IP, and domain intelligence sources during the period.

The WhoisXML API research team analyzed more than 7.4 million domains registered between 1 and 31 August 2024 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 the more than 59.2 billion domains from our DNS database’s A record full file released in the same month.

Next, we studied the top TLDs and associated threat types of more than 1.0 million domains detected as indicators of compromise (IoCs) in August.

Finally, we summed up our findings and provided links to the threat reports produced using DNS, IP, and domain intelligence sources during the period.

WhoisXML API is proud to be named one of the 2024 Inc. 5000 fastest-growing companies in America once again, specifically ranking 26th in the security category, 281 in California, and 1,847 overall.

The WhoisXML API research team analyzed more than 7.3 million domains registered between 1 and 31 July 2024 in this post to identify five of the most popular registrars, top-level domain (TLD) extensions, and other global domain registration trends.

We also determined the top 5 TLD extensions used by the more than 58.1 billion domains from our DNS database’s A record full file released in July 2024.

Next, we studied the top 5 TLDs and associated threat types of more than 1 million domains detected as indicators of compromise (IoCs) in the same month.

Finally, we summed up our findings and provided links to the threat reports produced using DNS, IP, and domain intelligence sources during the period.
