The Problem of Interceptor Top-Level Domains

Misdirected communication has obvious security and privacy ramifications and is an age-old problem that predates the Internet. In recent years it has been exacerbated by the arrival of electronic communication and the multitude of ways that communication can be misdirected. A new chapter in this age-old problem is being written with the proliferation of top-level domains (TLDs). This paper examines this problem in more detail and provides a full analysis of the current set of TLDs. In particular, we are concerned with TLDs that have a non-trivial probability of intercepting traffic intended for another domain. Intercepting TLDs have the potential of intercepting a lot of traffic since typically a TLD supports many domain names.

We have included the full text of my most recent paper on this subject:

Here is our latest report showing the potential interference among the TLDs:

Kraków, written in English as Krakow and traditionally known as Cracow, is the second-largest and one of the oldest cities in Poland. Situated on the Vistula River in Lesser Poland Province, the city dates back to the 7th century. Kraków was the official capital of Poland until 1596[ and has traditionally been one of the leading centres of Polish academic, economic, cultural and artistic life. Cited as one of Europe’s most beautiful cities, its Old Town was declared the first UNESCO World Heritage Site in the world.
