Howard,

Very few people require an internal DNS server, but it's a common
misconception that DHCP is hassle...it actually makes like
significantly easier.

Without DHCP, one has to manually supply IP address, subnet mask,
default gateway and DNS server IP addresses manually on each device. In
your case I gather this is some 22 devices? Into each you manually
entered all this data.

If, in the future, you want to change any of these details, you have to
go to all 22 devices and change it.

Which DHCP, you buy a new device and turn it on and it will generally
just work. Nearly all devices will come out of the box with DHCP
enabled. Indeed, DHCP is part of the UPNP specification meaning that
UPNP compliant devices *must* support DHCP by default. Otherwise it's
not plug & play, it's plug, configure and pray.

DHCP offers all of this convenience with almost no disadvantage
whatsoever. If you want your device to have a reserved address that
never changes, DHCP can do it. If you want to change the DNS on all
network devices, DHCP can do it. Automatically. Without re-configuring
the host machines.

Generally on a network, only 2 types of devices need a static, hard
coded IP address that isn't issued from a DHCP scope. The first are the
DHCP servers themselves. The second are the routers or firewalls,
usually this kind of hardware needs a static assignment.

All other devices, workstations, server, printers etc. can be fully
configured (and reconfigured) by DHCP. A fixed IP reservation can be
used if you want this dynamically assigned address not to change, but
assigning a hard coded address on the device is usually not best
practice.

The only time not using DHCP is advantageous is if your DHCP
infrastructure is broken and refuses to issue address to new devices.
In this case, the problem is that specific DHCP deployment, not the
protocol itself.
