All released versions of BIND, DHCP, AFTR and other ISC-hosted software are available for free download under the terms of the ISC License, a BSD style license.  Our version numbering system is straightforward.  All releases are signed with ISC's OpenPGP public key.  We make all of our software available at no charge.

NOTICE: Please see our Operational notification about a resolver.c issue with our April 4 releases of BIND.
