Preface
-------

This book is the fourth edition of a handbook of electronic mail addressing and net­works. If you routinely send electronic mail, this book will provide you with up-to-date, concise information on the major electronic mail networks around the world. If you are an administrator or network manager, your users can use this book to find information on networks themselves, without asking you.

This new edition provides readers with a directory and usage guide to over 210 of the world's research and educational networks, as well as commercial networks. The net­work information has been updated for 1994, with many new networks added. Also updated are the indexes to network name, network type, and country, as well as lists of many of the world's second- and third-level domains.

This new edition contains:

• Information on new networks.
• Updated information on networks that are reorganizing or have reorganized.
• Information on networks in the Commonwealth of Independent States, Eastern Europe, Africa, and the People's Republic of China.
• Networks not in the third edition.
• Updates of many of the existing networks described in the third edition that was published in 1993.

Many networks have had significant service or architecture changes, as well as new net­work connections or connections to new computers since publication of the third edi­tion.

Small, but significant changes occurred in many other networks, changes such as new higher-speed lines, new connections in the country, new services offered, and more. Often, network administrators have changed. Some of the networks previously existed for private use. Now the networks are public, and people are encouraged to contact colleagues in these countries.
