Researchers have complained for years about the lack of good
statistics about the internet for a couple fo decades, since the
end of NSFNET statistics.

What are the current estimates about the size of the Internet, all IP
networks including managed IP and private IP, and all telecommunications
including analog voice, video, sensor data, etc?

CAIDA, ITU, Telegeography and some vendors like Cisco have released
forecasts and estimates.  There are occasional pieces of information
stated by companies in their investor documents (SEC 10-K, etc).
