Mark Lottor of Network Wizards in Menlo Park CA USA released his latest results from the Internet's most basic and longest continuing measurement of it's size. The Domain Survey attempts to discover every announced host on the Internet by doing a complete search of the Domain Name System. The latest results were gathered during late July 1995. The data is available in the zone directory on ftp.nw.com, or http://www.nw.com/ John Quarterman of Texas Internet Consulting in Austin TX USA and publisher of Matrix News, then further analyzed the so-called 3-letter global domains that had previously resulted in uncertainty about the actual country host numbers. This is the first time this has been done on this scale and provides an entirely new perspective on how Internet's .com, .net, .org, .edu, and .int global domains are being used worldwide. Information will be published in the next Matrix News. See http://www.tic.com/ The Internet is a very complex, dynamic, distributed aggregation of more than 50 thousand autonomous networks. It defies definitive measurement. Nonetheless, these values constitute the potentially reachable host computers, and Lottor has carefully conducted these counts over many years, and provided the basis for valuable relative comparisons. A "host" in Internet terms is a computer that is connected and directly reachable as part of the Internet via a unique address. It does not include computers that are part of other networks peripheral to the Internet such as on-line provider customer terminals, bitnet, fidonet, etc. A Internet Research Task Force (IRTF) Survey Working Group is forming under Quarterman is further analyzing these statistics and methodologies to detect anomalies improve their value. HIGHLIGHTS Strategic highlights of the Lottor-Quarterman work include: - A new total host count of 6.6 million Internet computer hosts. - A strong exponential growth rate, but very slightly decreased. At the average rate of increase over the past 14 quarters, the total projected hosts the end of the decade is 101 million. - A surprisingly significant use of global 3-letter domains around the world. In some countries, they may encompass the preponderance of hosts in the country, as in the USA. - There are .COM domains in 54 countries, .NET domains in 57 countries, .ORG domains in 27 countries, including most of the United Nations agencies, and .EDU domains in 16 countries. - There are 1142 .COM domains encompassing 30,484 hosts in Canada; 241 .COM domains encompassing 13,260 hosts in the UK. - Hosts in 106 country domains were counted, an increase in 15 countries. See below. (Note that verification is not performed to verify these hosts are physically located in the country.) - The global commercial domain .COM continues not only to be the largest, but continues growing at a rapid rate. - Germany and Japan are exhibiting very rapid growth rates among industrialized countries with a first half rates of 41% and 40%, respectively. However, some of the German hosts appear to be announced twice, and are - In absolute terms, the USA had the largest jump of about 24%. The USA increase is subject to inherent uncertainties because of the mix of 3-letter global domains and the .US domain. - Strong Russian Federation growth continues at a 68% half year rate. - Most regional growth rates throughout the world continue at averages exceeding 40 percent. The statistics below are derived from an information system of this work over several years.

The analysis of 3-letter domains should be indicated as: John Quarterman Matrix Information and Directory Services (MIDS) Austin TX USA 2. Matrix News and the Matrix Maps Quarterly (MMQ) will include the new data in the next version. Samples of these elegant depictions are available at http://www.mids.org/ or send mail to mids@mids.org for copious information. 3. Some of Lottor's data shows hosts that are firewalled, and not reachable, even though their DNS servers permit ZONE transfers. Defining in the other direction may be easier, e.g., a computer that has a unique address and that can reach the rest of the Internet for interactive services such as WWW or FTP. 4. The number of new countries is 18, not 15. ai Anguilla ag Antigua and Barbuda bd Bangladesh bj Benin ky Cayman Islands ci Cote d'Ivoire do Dominican Republic gt Guatemala lb Lebanon mk Macedonia mc Monaco np Nepal sn Senegal tt Trinidad and Tobago tc Turks and Caicos Islands ug Uganda uz Uzbekistan vg Virgin Islands (British) ----------------------------------------------------------------- ############# # This message to Hungary-Online@hungary.yak.net # was from Dave Del Torto # # To unsubscribe, # send "unsubscribe" to # An announcement-only subscription (less volume) is available # at # Send mail to for more information, # or to if you need human assistance. #############
