The Versions of BIND


BIND is an acronym for Berkeley Internet Name Daemon. BIND implements this distributed database. For many years, BIND 4 was the one and only implementation, but it grew old and rusty and was replaced by BIND 8. In addition, BIND 4 had many security problems that have been fixed in BIND 8. At any time, the latest version of BIND 8 is the recommended version of BIND, especially for security-conscious sites. However, many sites still use some variant of BIND 4.

A good reason for still using BIND 4 is that most UNIX vendors still ship BIND 4 as their supported version. They have probably also modified it relative to the original version of BIND 4 that they used. On some sites, vendor support is important, so they use BIND 4.

If you use BIND 4 for some other reason, you should be sure you run the latest available version of BIND 4. Some of the most important and pressing security problems of BIND 4 have been fixed in the latest version. Also, if you use BIND 8, you should at all times use the latest available version of it. Chapter 15, "Compiling and Maintaining BIND," covers where to find the latest BIND version and how to get announce mails when new versions are published.
