The document defines name collisions in general and in the context of top-level domains in particular. The scope of inquiry divides the problem space into three areas.
In March 2019, the ICANN Board authorized study one, to proceed. This study will examine all prior work on the issue of name collisions. After that, it will produce a summary report that brings forward important knowledge from prior work into this study. It will act as a primer for those new to the subject. It will create a list of results of the data used in past studies, identify gaps, if any, and list additional data that would be required to successfully conduct the two additional identified studies. Furthermore, it will provide information that will facilitate a decision on whether the NCAP should proceed with studies 2 and 3 based on the results of the survey of prior work and the availability of data.
