You want servers to have the same IPs, always. That can be done by
configuring the computers, individually. For clients, it's usually not
too much of an issue whether their IP changes. And it's usually easiest
to configure clients at the server. That way, you only have to
configure things on one machine (everything controlled on your server).
For the clients, there are two alternatives to completely randomly
assigned dynamic addresses: Tying them to the same IPs, always. Or, it
may be good enough to simply make them far less likely to change IPs.
For cases where it's merely a question of convenience, and you don't
really need to fix them, just set your DHCP server so that default lease
times are long enough that a client will get the same IP as last time,
by default.
If you use Samba, particularly with some actual Windows client machines,
you may find it works more smoothly if the client machines always use
the same IPs. SMB can be very slow at dealing with changes to addresses
of machines.
