When this message appeared in /var/log/messages, I removed lines in
the named.conf until it is barebones but the error persists. How do I
determine what is being referenced as '4'?

---------/var/log/messages---------
starting BIND 9.2.3 -u named -t /var/named/chroot
using 1 CPU
named startup succeeded
loading configuration from '/etc/named.conf'
/etc/named.conf:2: expected prefix length near '4,'

// generated by named-bootconf.pl

options {

// query-source address * port 53;
};

//

//

controls {
inet 127.0.0.1 allow { localhost; } keys { rndckey; };
};

include "/etc/rndc.key";

zone "." {
type hint;
file "named.ca";
};
zone "0.0.127.in-addr.arpa" {
type master;
file "named.local";
};

Thank
