Let's suppose
that guy has got a PC with a Network Interface Card
and the MAC address of that NIC is 00:12:34:56:78:9a

If at _start-up_ your /etc/ethers file contains this line
00:12:34:56:78:9a	192.168.5.100

AND

your /etc/dnsmasq.conf file contains this line
dhcp-range=192.168.5.100,192.168.5.200,2h

then that NIC with that MAC address (and only that) will get the 192.168.5.100 IP address.

Have you ever seen the man of ethers - for example at
http://unixhelp.ed.ac.uk/CGI/man-cgi?ethers

Good luck,
