The location of the root.cache file is specified by the cache directive in the named.boot(4tcp) file. The latest version of the Internet root.cache file is available from ftp://rs.internic.net/domain/named.root, or by using the command dig . ns. Because the contents of this file change periodically, retrieve it regularly to ensure that you have the current version.
