The DHCPv4 server is implemented as <command>b10-dhcp4</command>
daemon. As it is not configurable yet, it is fully autonomous,
that is it does not interact with <command>b10-cfgmgr</command>.
To start DHCPv4 server, simply input:
<screen>
#<userinput>cd src/bin/dhcp4</userinput>
#<userinput>./b10-dhcp4</userinput>
</screen>
<command>b10-dhcp4</command> is a BIND10 component and is being
run under BIND10 framework. To add a DHCPv4 process to the set of running
BIND10 services, you can use following commands in <command>bindctl</command>:
<screen>&gt; <userinput>config add Boss/components b10-dhcp4</userinput>
&gt; <userinput>config set Boss/components/b10-resolver/kind dispensable</userinput>
&gt; <userinput>config commit</userinput></screen></para>
Depending on your installation, <command>b10-dhcp4</command>
binary may reside in src/bin/dhcp4 in your source code
directory, in /usr/local/bin/b10-dhcp4 or other directory
you specified during compilation.
<para>
To shutdown running <command>b10-dhcp4</command>, please use the
following command:
<screen>&gt; <userinput>dhcp4 shutdown</userinput></screen>
or
<screen>&gt; <userinput>config remove Boss/components b10-dhcp4</userinput>
&gt; <userinput>config commit</userinput></screen></para>

At start, the server will detect available network interfaces
and will attempt to open UDP sockets on all interfaces that
are up, running, are not loopback, and have IPv4 address
