weird case for IP duplicated on LAN

[IT Support]

Hi

Thanks Nial for your answer, about logs, just I can see this:

dhcpd: DHCPDISCOVER from 00:88:88:88:88:88 via 192.168.0.120
dhcpd: DHCPOFFER on 192.168.0.20 to 00:88:88:88:88:88 via 192.168.0.120


Hi Sten about your answer:

Suggest you look for a ClientID in both hosts, probably the same.

How can I check the ClientID?
