IO Domains in Alexa Top 1 Million

There seems to be a trend with recent startups and interesting dev projects jumping on the .io top level domain names. One can assume that it has to do with the connotation to input-output or I/O abbreviation in programming. Ofcourse, .io is the domain name for the Indian Ocean territory, an archipelago somewhere between Africa and Indonesia. There are some good lists of IO domains out there but have you ever wondered how many io domains are in Alexa? Alexa attempts to estimate the popularity of websites and they provide a list of 1 million domains for free. Here is a list of over 400 .io domains in the Alexa Top 1 Million list ordered by Alexa rank:
