The Berkeley Internet Name Domain (BIND) implements an Internet domain name server. BIND is the most widely-used name server software on the Internet, and is supported by the Internet Software Consortium, www.isc.org. . Please consider switching to bind9, which is considerably newer. See http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-0527 if you are thinking of using BIND 8 as a forwarder.
