Start with "man dhcpd.conf" and find the section on Dynamic DNS 
Updates where it's explained (you'll want to be using update style 
"interim"). If your DNS is correctly configured (ie the SOA records 
for the zones you are updating are accurate) then the only change you 
need on the DNS server is to allow updates by IP address from your 
DHCP server - but this is insecure. For security, you'll probably 
want to use signed updates which is described in the man page.

If you still don't understand something when you've read the man 
page, then feel free to come back with more specific questions.
