Subdomains are set in the web server configuration files and have nothing to do with any BIND/name server settings. Name servers deal with domain names. Sub domains have the same domain name. Wanting something like freddie.domain.com needs you to use name-based virtual hosting on the web server and setting it as an alias name. In some cases (
www.domain.com, ftp.domain.com) a brwoser will you the implied subdomain to switch the data transfer protocoll (HTTP, FTP, etc).
