Determine the physical, real-world location of a person or device using IP address

We Know No Boundaries!

The term Internet Protocol address or more commonly known as an IP address definitely needs no introduction to most people. It is a unique number that devices use in order to identify and communicate with each other on a computer network. With DNS Lookup API  from WhoisXmlApi, users can easily map a domain name to its IP address. While knowing the IP address can have its uses, many professionals need to know the real world location of the IP address as well, be it to detect online fraud or to locate online visitors. This is now possible with Geolocation technology, which helps determine the physical, real-world location of a person or device using IP address. And we at WhoisXmlApi are proud to venture into this arena with the release of our latest product IP Geolocation API, which caters to just that!

Using BASH and other Linux tools on Windows 10 for processing Whois data

This is technical blog for our subscribers of daily or quarterly data feeds to facilitate the use of our client-side BASH scripts and perform other operations on their data.


This blog is for you if you are a Windows user and want to use BASH for processing Whois data. We describe how you can set up an environment in Windows which does not only facilitate the use of BASH scripts of WhoisXML API, but gives a general access of many tools and features available mainly in Linux and UNIX type systems. So if you are interested in a Linux-type approach of handling these data or developing, but you do not want to set up a separate (virtual) computer with a Linux and you want to see your files within your Windows system directly, please proceed reading.

Unintended consequences of GDPR on privacy and Spam

On May 25, 2018 the European Union’s General Data Protection Regulation will go into full effect. This means that privacy regulations will have a significant impact on how companies handle peoples personal data. General Data Protection Regulation is a regulation that is designed to protect privacy of EU citizens and its residents. What are some other consequences that the GDPR can have? It means that they can severely restrict access to technology for its EU residents and companies. So, what does this mean for the future of Whois? Well we have all heard about GDPR and its effect on Whois. I echo the sentiment by Neil Schwartzman that restricting Whois access would increase spam. Why? Antispam software relies on Whois data to detect spams. Spammers will be able to gain access to people’s contact information from everywhere on the web, including data warehouses, social media, and so many others. They will continue do what they have been doing for years so long as there are commercial incentives.

Setting up a whois database from WHOIS XML API data

This is technical blog describing how you can download bulk data from a data feed subscription at WhoisXML API, and how you can use them to set up a local Whois database on your server.


Our starting point is that you need data for some domains in files or in a database, for a given period of time. We describe how to achieve this goal in two Sections: the first one describes how you can access and download the data you need. The second one describes how to set up a database from the downloaded data, ranging from relational databases such as MySQL to other, noSQL storage methods, such as MongoDB.
