It looks like dnsmasq assigne one IP to two nodes: IP MAC 10.20.1.131 0c:c4:7a:1d:90:fe 10.20.1.131 0c:c4:7a:1d:92:76
10.20.1.45 0c:c4:7a:1d:91:64 10.20.1.45 0c:c4:7a:1d:93:da
As Alexandr Shaposhnikov suggested in another bug setting dhcp-sequential-ip option in dnsmasq fixes the problem. This change requires more investigation
