[Dnsmasq-discuss] dnsmasq.lease file question

I too have noticed this strange phenomena, and not just in DNSMasq. On
almost every DHCP server I have ever used, when I look at the lease
file, there is never hardware info for linux boxes. Personally, and my
understanding of the underlying mechanics of DHCP is very limited, I
thought that all requests for a DHCP address included the mac address,
in order for an answer to be directed to the correct machine. Therefore,
the DHCP server should already know the hardware address. Why it
forgets, and it never gets listed, is beyond me. Maybe someone else
could enlighten us :)
