      <p>1 - "Beginning with Kea 1.6.0 the lease valid lifetime is
        extended from a single value to a triplet with minimum, default
        and maximum values using <code class="docutils literal
          notranslate"><span class="pre">min-valid-lifetime</span></code>,
        <code class="docutils literal notranslate"><span class="pre">valid-lifetime</span></code>
        and <code class="docutils literal notranslate"><span
            class="pre">max-valid-lifetime</span></code>. When the
        client does not specify a lifetime the default value is used,
        when it specifies using a DHCP option code 51 this value is used
        if it is not less than the minimum (in this case the minimum is
        returned) or greater than the maximum (in this case the maximum
        is used)."</p>

        servers should send values for T1 and T2 that are 50% and 87.5%
        of the lease lifetime, respectively. By default, kea-dhcp4 does
        not send either value. It can be configured to send values that
        are specified explicitly or that are calculated as percentages
