There new build version of BIND v9 DNS server special edition for Sun UltraSparc T1/T2+ CPU platform

New Features

  • Zones may be dynamically added and removed with the “rndc addzone” and “rndc delzone” commands. These dynamically added zones are written to a per-view configuration file.

  • Added new “filter-aaaa-on-v4” access control list to select which IPv4 clients have AAAA record filtering applied.
  • A new command “rndc secroots” was added to dump a combined summary of the currently managed keys combined with statically configured trust anchors.
  • Added support to load new keys into managed zones without signing immediately with "rndc loadkeys". Added support to link keys with "dnssec-keygen -S" and "dnssec-settime -S".
