<br>
I have now configured my Kea installation with many subnets,
each with <br>
their own reservations. It's working well.<br>
<br>
There's also one global reservation set for hosts that are
configured <br>
without an IP so they can connect in the dynamic range of
any subnet.<br>
<br>
I wanted to do a test of what would happen if a host ether
was not <br>
referenced in either the subnet or global sections.<br>
<br>
I took one host which was getting a reserved IP in a subnet,
released <br>
the IP, then changed the host ethernet address in the Kea
config file so <br>
that the host would no longer be recognized.<br>
<br>
When I DHCP renew on the host, I now get an IP in the
dynamic range. <br>
This isn't the behaviour I want. Since the host doesn't
have a <br>
reservation either in a subnet or in the global pool, I want
to be <br>
denied an IP.<br>
<br>
What option am I missing?<br>
<br>
Jason.<br>

<div>Remove the dynamic range, if you don't want dynamic
clients. DHCP Reserved clients should be outside any range.</div>
<div><br>
</div>
<div>(or limit it to some class of clients or list of allowed
mac addresses or other client ids or vendor ids)</div>
<div>... at least that's how it works in dhcpd.</div>

<p>Hi Bob,</p>
<p>Thanks for your response.<br>
</p>
<p>Perhaps I'm explaining what I want to do poorly or using the
incorrect terminology. My apologies.<br>
</p>
<p>Each subnet has host reservations based on ethernet address and
IP pairs for many hosts. Each subnet also has a dynamic pool.
The IPs distributed via host reservation are allocated from
outside the dynamic pool.</p>
<p>The global reservations section includes ethernet address and not
IP for hosts that should be able to get an address no matter which
subnet they plug into. The IPs distributed for these global
reservations should be from the dynamic pool ranges attached to
each subnet.</p>
<p>Hosts that have neither an entry in the subnet host reservation
list, or the global reservation list should not be able to get an
IP address.</p>
<p>That's what I was doing with ISC DHCPd before. I'm sure there's
a way to do this with Kea, but I could just use assistance
figuring out which options I need.</p>
<p>Thanks!<br>
</p>
<p>Jason.</p>
