This is a feature for our customers. We have many (business)customers
with mailservers, webservers, vpn or stuff like that. Binding the host
(client) seams to be not the solution, because when a customer wants
to change his router he needs a support call :(

The limit on client IP's isn't the problem, i can do that wirh max_cpe
on the cable modem. I just want fixed ip addresses on cable modem mac.
somthing like:

host { match if option agent.remote-id = 01:A4:05:14:d3:e1;
fixed-address; }

would be very nice.
the solution with classes and pools seams to work, but i know it isnt
the right way to be scaleable for many customers :/

the only way to split the customers to many seams also not the solution.

i've also tried the ldap patch for dhcpd, but there only the host
table can be dynamic...
