<para>This file is used to define zones in terms of subnets and/or

individual IP addresses. Most simple setups don't need to (should not)

place anything in this file.</para>

<para>The order of entries in this file is not significant in determining

zone composition. Rather, the order that the zones are declared in <ulink
