BIND 8 Highlights
• DNS Dynamic Updates (RFC 2136)
• DNS Change Notification (RFC 1996)
• Completely new configuration syntax
• Flexible, categorized logging system
• IP-address-based access control for queries, zone transfers, and updates that may be specified on a
zone-by-zone basis
• More efficient zone transfers
• Improved performance for servers with thousands of zones
• The server no longer forks for outbound zone transfers
• Many bug fixes
BIND 8 is much more configurable than the previous release of BIND. There are entirely new areas of
configuration, such as access control lists and categorized logging. Many options that previously applied to all
zones can now be used selectively. These features, plus a consideration of future configuration needs led to the
creation of a new configuration file format.
