Look in the syslog output. You may need to set up a specific log file
for dhcp using the log-facility statement in dhcpd.conf, and
corresponding setup in /etc/syslog.conf

% grep local /usr/local/etc/dhcpd.conf
log-facility local7;

% grep local /etc/syslog.conf
local7.debug                                    /var/log/dhcp/dhcpd.log

which gives log entries that look like this:

Dec  9 23:29:30 drill dhcpd: [ID 702911 local7.info] DHCPREQUEST for 
192.168.14.21 from 00:1b:11:18:b9:d2 via hme0
Dec  9 23:29:30 drill dhcpd: [ID 702911 local7.info] DHCPACK on 192.168.14.21 to 
00:1b:11:18:b9:d2 via hme0

Alternatively try webmin which has a dhcpd capability.
