Eu tenho problema com dhcp3-server 3.1.1-6+lenny4 . Meu dhcp-server envia "estranho" IPs para DNS e NTP servidores em DHCP ACK apesar da configuração que não possui esses IPs. Em ACK packet podemos ver os endereços "estranhos" como:
49.57.50.46 or 49.54.56.46 etc.
A configuração do servidor DHCP é:
deny bootp;

#
# The ddns-updates-style parameter controls whether or not the server will
# attempt to do a DNS update when a lease is confirmed. We default to the
# behavior of the version 2 packages ('none', since DHCP v2 didn't
# have support for DDNS.)

O arquivo subnet.list.conf contém configuração de hosts fiexed e eu o limito por apenas alguns aqui.
Abaixo deste link existe um limite de comunicação DHCP: DHCP_CAP
O servidor está rodando sob o Debian 5 no VMware Host.
