BIND installer packages for MacOS X 10.4/10.5 PowerPC (ppc)
Apple does not provide update to older MacOS X versions (such as 10.4 "Tiger") anymore. However these machines are still good to run a caching or an authoritative DNS Server.
MacOS X comes with ISC BIND pre-installed, but without security updates, running an old version of BIND on MacOS X is a risk.
To find out the current version of BIND installed on a machine, open the Terminal.app and enter "named -v":
$ named -v BIND 9.4.2-P2
