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.

We’re excited to announce a new feature designed to enhance security and control within your organization while using WhoisXML API products—parent-child API keys. This feature allows account administrators to create and manage individual API keys for different members on their team.

The parent-child API key feature is available for enterprise users only. Please contact us to check your eligibility or if you are an enterprise user and want to turn this feature on.

WhoisXML API has been actively upgrading its WHOIS history product coverage for more than 14 years now of WHOIS data collection, aggregation, and processing. In recent years, we have had several notable repository expansions. From 13.7+ historical WHOIS records in Q1 2022, our coverage rose to 15.6 billion in Q1 2023. This year, we saw an estimated 28% increase, with our historical WHOIS data now spanning more than 20 billion records.

We are thrilled to announce that the coverage of our premium DNS Database Download significantly improved over the past few months. The most recent measurement in 2024 showed that the database’s total number of DNS records increased by 578% compared to May 2023. 

More precisely, there was a 1,313% increase in A records and a 700% increase in the total number of AAAA records. Overall, DNS Database Download now contains more than 35.3 billion DNS records.
