> How many other Belize defuncts do they have? How many offshore countries like Belize are there in the region?
Based on my cursory knowledge of offshore corporate registrations in Belize, Panama and the Cayman Islands, identifying those locations which are only mailboxes versus actual business office addresses should not be overly complicated or difficult.
In the era of Google Street View for most major urban areas the initial search process can be done remotely, such as when it appears that dozens of companies occupy one street address of a very small office building.
For instance look at the company registration offices, with hundreds of corporate entities sharing one office suite address, which were created by Mossack Fonseca in Panama City.
The same principle would apply not just to LACNIC, but also to anybody who wanted to go in detail through the number of ISPs and hosting companies that nominally exist in Malta and Cyprus.
