<h1 id="how-to-reassign-a-static-ip-address-with-dnsmasq">How To Reassign a Static ip address with dnsmasq</h1>
|
|
<p>On your router you can assign static ip addresses for various machines
|
|
in your network, by writing the reservations in the file <code>/etc/dnsmasq.conf</code>.</p>
|
|
<p>These will be in the form as below.</p>
|
|
<p><code>dhcp-host=<mac address>,<ip address></code></p>
|
|
<p>So here's how you transfer an existing static ip address assignment to
|
|
a new client machine. Begin by editting the file <code>/etc/dnsmasq.conf</code> on
|
|
your router, and update the mac address associated with the intended
|
|
ip address.</p>
|
|
<p>Next, temporarily stop dnsmasq.</p>
|
|
<pre><code class="bash">systemctl stop dnsmasq
|
|
</code></pre>
|
|
|
|
<p>Next shutdown networking on the new client machine. Shutting the machine down might work,
|
|
or the command <code>dhclient -v -r</code> might get the job done (you will lose the connection).</p>
|
|
<p>Now on the router, edit the file <code>/var/lib/misc/dnsmasq.leases</code>, and delete the pre-existing
|
|
lease for the old client machine that will no longer exist.</p>
|
|
<p>Restart dnsmasq on the router,<br />
|
|
and then restart networking on the new client machine.</p>
