Query: A deep dive into the accuracy of IP Geolocation Databases and its impact
  on online advertising   The quest for every time more personalized Internet experience relies on the
enriched contextual information about each user. Online advertising also
follows this approach. Among the context information that advertising
stakeholders leverage, location information is certainly one of them. However,
when this information is not directly available from the end users, advertising
stakeholders infer it using geolocation databases, matching IP addresses to a
position on earth. The accuracy of this approach has often been questioned in
the past: however, the reality check on an advertising DSP shows that this
technique accounts for a large fraction of the served advertisements. In this
paper, we revisit the work in the field, that is mostly from almost one decade
ago, through the lenses of big data. More specifically, we, i) benchmark two
commercial Internet geolocation databases, evaluate the quality of their
information using a ground truth database of user positions containing more
than 2 billion samples, ii) analyze the internals of these databases, devising
a theoretical upper bound for the quality of the Internet geolocation approach,
and iii) we run an empirical study that unveils the monetary impact of this
technology by considering the costs associated with a real-world ad impressions
dataset. We show that when factoring cost in, IP geolocation technology may be,
under certain campaign characteristics, a better alternative than GPS from an
economic point of view, despite its inferior performance.
