      <title>Running Kea servers directly</title>
      <para>Kea servers can be started directly (without a need to use
      <command>keactrl</command>). To start DHCPv4 server run the following
      command:
      <screen># <userinput>kea-dhcp4 -c /path/to/your/kea4/config/file.json</userinput></screen>
      And, to start the DHCPv6 server run the following command:
      <screen># <userinput>kea-dhcp6 -c /path/to/your/kea6/config/file.json</userinput></screen>
