Yeah, sometimes the old BIND resolver is called the "BIND4/8" resolver. It looks like the last BIND resolver code imported into glibc is from BIND 8.2.3-T5B. > BIND9 was a new codebase with very different internal library APIs, and an > ambition to completely revamp the libc -> resolver interface - this is > what the lwresd stuff was about.

There's also the caveat that BIND 9, until 9.6.0, also shipped a copy of the old BIND4/8 "libbind" resolver (configure --enable-libbind). At which point it was split out into a separate tarball distribution (https://ftp.isc.org/isc/libbind/) and given the arbitrary version number 6.0. -- Robert Edmonds _______________________________________________ Please visit https://lists.isc.org/mailman/listinfo/bind-users to unsubscribe from this list bind-users mailing list bind-users@lists.isc.org https://lists.isc.org/mailman/listinfo/bind-users
