Downloading bulk WHOIS data: why and how?
In spite of all of its known deficiencies, WHOIS data still play a crucial role in e.g. IT security, marketing research, scientific investigations related to the Internet or the World Wide Web and the domaining business. They provide essential information on the ownership and registration details of a domain, including relevant dates such as that of registration and expiry.

The amount of data that can be possibly generated, collected or processed with computers is well beyond our imagination. In high-performance computing applications, such as, e.g. in weather forecast calculations, the size of data sets is of order of petabytes. But what are we interested in, after all, when looking at a weather forecast? A few lines of information describing what the weather will be like in the next few days. Or, maybe, a weather map which is a file still not bigger than an average family photo. This illustrates that in many cases we need a huge amount of data, but the data size of the real information we need to get out of it is really small. Of course it does not mean that we do not in fact get very much information from this small-sized result dataset.
