The syntax for 'if' and regex matches are explained in the dhcp-eval(5)
man page.
Other useful DHCP man pages shipped with the ISC distribution are:
dhcpd.conf(5), dhcp-options(5), dhclient.conf(5), dhcpd.leases(5) and
dhcpd(8).
There was a recent post (in the last month) that covered a similar
topic, with some configuration that may be useful for you.
