Definitely. You have to limit the range in ether case so that your
static IP's are not in the dynamic range. You also have to remember
to update the DHCP server if you change NICs. (Or configure the new
NIC to use the old MAC address.)

Dnsmasq lets you combined the two in one program. It is also much
simpler to set up then BIND and DHCPD. It is also easy to set it up
to use your ISP's name servers. It works well with dial-up
connections. But it does not have the flexibility of BIND and DHCPD.
It is useful for setups that do not need it. It also has options
that BIND does not - thing like including the information from
/etc/hosts.

The one you use depends on your needs. I find that dnsmasq fits in
nicely when your LAN is a bit large for just using /etc/hosts and
static IP's, but not really big enough that using BIND and DHCPD is
called for... It also work well when you need to be able to quickly
and easily change the forwarding name servers. (Firewall systems
that get the WAN information using DHCP.)
