Each host has an IP Address.  The estimate was an average of 20 USERS per
IP Address.  You have prodigy.com (1 IP address) and 2 million USERS.
You have places like UCB where it's 1 user/ip address.

I have 3 net addresses and 5 e-mail hosts.

At one point in March 1994 there were supposedly 200 Million accessible
e-mail addresses.  The probability is that many were duplicates (I had 
e-mail addresses on prodigy, compuserve, mcimail, digex, aol, delphi,
and dowjones).  I only used 2 of them for economic reasons.

There are also several wais and gopher sources.
I haven't looked lately.  Some of the more informational statistics are
things like TCP conects, gigabytes/day, usenet postings, e-mail messages,
traffic on the back-bones, DNS hosts registered, downloads of TIA, 
Trumpet, NetScape, Mosaic, and Cello (each download spawns an average of 
2 users/month).

E-mail addresses, newsgroup posters, and ip addresses are kept in public 
registries.

Isn't it great, we're so successful, we don't even know how well we're doing.
