I have just checked on my environment what's in the dnsmasq.leases file:

1547246444 00:50:56:85:23:ea 10.198.10.223 win-vm 01:00:50:56:85:23:ea
1547276503 00:50:56:85:f1:86 10.198.10.37 linux-vm 01:00:50:56:85:f1:86

As you see the Client-ID (5th field) is the MAC + "01:" as prefix.

Many Thanks
Michael
