Pi hole assigns incorrect IP to client

[bkbartje]

Hello,

I'm using pihole as a dhcp server, I assigned some static leases to some clients because those devices should always use the same ip. Those static leases are outside the range of my DHCP server,
but 1 device keeps getting an incorrect IP.

as you can see, the mac address matches.
.233 was the address originally issagned, but I removed that, reset the device.
the leasetime is 24hours.
but after 3 days, the ip is still incorrect.

I think I need to flush some cache, but not sure, what can I do?

Have you verified that the MAC ID is current for that client? Some operating systems change the MAC ID for each network to which the client connects.

[bkbartje]

yes, it's accurate
if the mac was different, it wouldn't be in the list with active leases.
first I thought the device itself remembered for to long, but then the address wouldn't re appear in the list.

What the relevant lines for that client in

cat /etc/pihole/dhcp.leases 
          
cat /etc/dnsmasq.d/04-pihole-static-dhcp.conf

1681578012 84:d6:c5:03:6b:cf 192.168.180.233 * 01:84:d6:c5:03:6b:cf

and

dhcp-host=84:D6:C5:03:6B:CF,192.168.180.24,SolarEdge-Lan

Try manually removing the first entry and reconnect that device to the network.

[bkbartje]

strange, I already tried that, then it didn't work, but now it does,
the only difference now was that I now unplugged the network cable, then removed the entry(using the interface) and then plugged it back in, where earlier I removed the entry, then restarted the device.

Thanks , because it works.
