Biannual Strategic Note                                15 Feb 1998

   INTERNET SURVEY REACHES 30 MILLION INTERNET HOST LEVEL
                NEW SURVEY METHOD IMPLEMENTED


Herndon VA, USA.  The latest results from the Internet's most 
basic and longest continuing measurement of it's size were just 
released by Mark Lottor of Network Wizards at Menlo Park CA USA.  
The Domain Survey attempts to discover every host on the Internet 
by using the Domain Name System.  The results were gathered 
during Jan 1998.  The raw data plus some Network Wizards charts 
are available at <http://www.nw.com/>.


Lottor's measurements show that the Internet currently consists
of countless autonomous networks with 29,670,000  "advertised" 
connected computers in 240 countries and territories.  Because of 
the unknown and potentially unlimited numbers of multiuser computers 
and network or application gateways, it is not possible to correlate 
any of this information with the number of end users.  However, see 
Quarterman's estimates at <http://www.mids.org>


Lottor's new method for accomplishing the survey can be found at 
<http://www.nw.com/zone/WWW/new-survey.html>.  Although the new 
method will allow more accurate continuing surveys, it is
sufficiently different so as to prevent definitive comparisons with 
older data.  However, some strategic highlights can be observed:


o The figure of 29.6 million hosts represents a significant new
  benchmark for the number of Internet hosts.  By adjusting 1995-97
  data and combining it with Jan 1998 data, it appears the current 
  Internet annual host growth rate is probably between 40 and 
  50 percent.  Based on the average growth over the past three years,
  the new projected host figure for Jan 2000 is 90 million.


o The new survey method reveals a larger number of .COM hosts -
  the largest domain by far with with 8.2 million hosts, and
  constituting 28 percent of all hosts.  


o All the generic domain host counts are significantly larger using
  the new survey method.  This includes .EDU, .NET, .MIL, .ORG,
  and .GOV.  Together, the hosts in all the generic domains 
  constitute 66 percent of all Internet hosts.


o The new survey method also provides some useful information
  about the Internet Domain Name System structure.  More
  than 78 percent of the 2nd and 3rd level domain structure 
  resides within the generic top level domains .COM, .NET, 
  .EDU, .ORG, .MIL, and .GOV.  See table below.


o Without subsequent processing to attribute the three
  letter global domains to a country previously done by
  John Quarterman of MIDS <http://www.mids.org/>, it's 
  not possible to determine final country figures.  However, 
  it appears approximately that the same 60% - 40% balance 




  between USA versus non-USA, proportions may be actually
  higher that previously measured.


o Hosts in 240 country domains appear to have connectivity.
  The domains of 23 countries or territories appeared on the 
  host count for the first time - apparently connecting 
  since July 97.  (See below.)  Increasingly, some very remote 
  places are achieving connectivity.  However, some of these 
  hosts may not be actually physically located in the country.




This and previous strategic summaries, as well as very attractive 
new graphic presentations of all these values and trends can be
