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.
This blog explains, without completeness, how you can make use of Whois data, especially in a form of a Whois database in various areas of marketing, IT security, etc.
In the present blog we give a holistic overview, of at least a part of applications of WHOIS databases. As a practitioner or a researcher, you can broaden your insight get some inspiration and possibly find new ideas and starting points for further study.
