WhoisXML API Joins the Global Anti-Scam Summit (GASS) London 2025

Alexandre François (Product Marketing Director) and David Hagberg (Strategic Partnerships Director) represented WhoisXML API at the Global Anti-Scam Summit (GASS), held in Westminster, London, U.K., on 26–27 March 2025. They joined more than 1,000 in-person and virtual attendees at the event, which aimed to bring together a community of fraud fighters and build a framework for tackling fraud and scams—two growing problems worldwide, in both developed and developing countries.

The event brought to light the urgency of fighting against cybercrime, especially since Internet users are up against highly organized and determined fraud groups. In fact, one in four individuals globally has fallen victim to fraud and scams, with fraudsters having amassed nearly US$1.03 trillion in 2024.

Catch Domain Events Earlier with the includeCandidates Parameter in Real-Time Domain Registration Streaming

We are excited to announce that our development team has upgraded Real-Time Domain Registration Streaming to include a feature called “includeCandidates,” an optional Boolean parameter that allows users to immediately obtain simplified domain records directly from zone files before they undergo newly registered domain (NRD) processing.

The candidate records only have two fields, namely, “domainName” and “reason,” where the latter field can be “added” for NRDs or “dropped” for recently removed domains. 

Newly Registered Domains (NRD) Data Feed Now Offers Up to One Year of Historical Files

We are excited to share that Enterprise and Ultimate subscribers of the Newly Registered Domains (NRD) Data Feed will now have access to past data feed files, giving security professionals deeper context to help trace threat patterns and evolution. 

In particular, NRD Enterprise users can access files produced in the past 30 days from their subscription date, while NRD Ultimate users can go as far back as 365 days. With this new enhancement, WhoisXML API users can now use NRD data feeds to:

March 2025: Domain Activity Highlights

The WhoisXML API research team analyzed 8.2+ million domains registered between 1 and 31 March 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 59.2+ billion domains from our DNS database’s A record full file dated 6 March 2025.

Next, we studied the top TLDs of 1.1+ million domains detected as indicators of compromise (IoCs) this March.

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

Wildcard DNS Records: Use Cases and Associated Risks

As an organization’s internet infrastructure grows, it requires more and more configuration, setup, and decision-making—from selecting a reliable name server to determining the right types of DNS records and setting the appropriate time-to-live (TTL) values. One of those decisions is whether or not to create a wildcard DNS record, a feature that most hosting providers, registrars, and DNS providers offer.

In this post, we discuss what a wildcard DNS record is, how it helps, and any risks associated with it.

What is Withheld for Privacy ehf (and How to See WHOIS Data Beyond It)

When you run a WHOIS lookup for a domain name you’re interested in, you may find that some details are redacted for privacy. You can’t see who owns that domain because “Privacy service provided by Withheld for Privacy ehf” is on the registrant organization field. What, exactly, does this mean? And is there a way to find out the actual domain owner’s email address and contact them? 

We’ll talk about registration data redaction in general and Withheld for Privacy ehf in particular in this post, as well as cover how it works, and some of the other most common domain privacy protection companies. We will also demonstrate how you can possibly still uncover domain ownership data despite redaction.
