Abstract

This document illustrates the growth of the Internet by examination of entries in the Domain Name System (DNS) and pre-DNS host tables. This memo provides information for the Internet community. It does not specify an Internet standard. This memo defines an extension to the Management Information Base (MIB) for use with network management protocols in TCP/IP-based internets. In particular, it defines objects for managing the Frame Relay Service. [STANDARDS-TRACK]

Abstract

This document illustrates the growth of the Internet by examination of entries in the Domain Name System (DNS) and pre-DNS host tables. DNS entries are collected by a program called ZONE, which searches the Internet and retrieves data from all known domains. Pre-DNS host table data were retrieved from system archive tapes. Various statistics are presented on the number of hosts and domains.

Introduction

This document provides statistics on the growth of the Internet by examining the number of Internet hosts and domains over a 10-year period. Before the Domain Name System was established, practically all hosts on the Internet were registered with the Network Information Center (SRI-NIC) and entries were placed in the Official Host Table for each one. Data on the number of hosts for pre-DNS

years comes from copies of the host table at selected times. The DNS system was introduced around 1984 but took almost 4 years before it was fully implemented on the Internet. However, by this time many hosts were no longer registered in the Host Table.

In 1986, the ZONE (Zealot Of Name Edification) program was written. ZONE was originally intended to be used during the host-table-to-DNS transition period. ZONE would "walk" the DNS tree and build a host table of all the information it collected. This host table could then be used by sites that had not yet made the DNS transition. However, ZONE was never used for this purpose. Instead, it was found to be useful for collecting statistics on the size of the domain system and the Internet.

ZONE could not collect complete data on the DNS until around 1988, because early versions of BIND (the po...
