Finished

Still under heavy construction.  ie it is not done yet.  doing exec sums first.

BIND 8 is the version used in FreeBSD 4.7 installed by default.
BIND 9 is avalible (ports/net/bind9) but I'm using 8 main because in comes already installed and just has to configured and that's what I used in the past.

Of course if you have DNS provided by your ISP just use the forwarders.

Configuring

Create the local reverse DNS zone file.
    # cd /etc/namedb
    # sh make-localhost
This creates /etc/namedb/localhost.rev   I've seen this call named.local in other implementations of BIND.  It also creates "localhost-v6.rev" but I'm not using IPv6.  If you change your hostname or domain name you will have to edit/rebuild these files.


Create the main confuration file named.conf

##** begin named.conf
options {
    directory "/etc/namedb";
};
zone "." {
    type hint;
    file "named.root";
};
zone "lab.ts" {
    type master;
    file "lab.ts";
};
zone "0.0.127.in-addr.arpa" {
    type master;
    file "localhost.rev";
};
zone "1.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.IP6.INT" {
    type master;
    file "localhost-v6.rev";
};
zone "10.168.192.IN-ADDR.ARPA" {
    type master;
    file "192.168.10";
};
##**end named.conf

In the options area we have the directory where the files are located.
The rest of the enteries are for the zone information files.
zone name, type, and filename.


Create the rest of your zone files

The files called in named.conf.
named.root    The root zone file.  Points to root name servers
lab.ts              The local zone file.  For your local domain
192.168.10     The reverse lookup.  Getting the host name when you have the IP address.

named.root
This file is made available by InterNIC registration services under anonymous FTP as
/domain/named.root
on server   FTP.RS.INTERNIC.NET
