The DNS servers they obtain through DHCP (or pre-configured in
their /etc/resolv.conf, or other client equivalent) should be
recursive/caching servers, so that the clients can obtain information
about other machines on the Internet, etc.... DDNS is important on
authoritative servers, which would be providing information *about*
the clients, to other machines on the Internet.
For various reasons (including security), the caching/recursive
machines and the authoritative machines should be two separate sets
of systems. Therefore, you should be able to update the
authoritative machines to use DDNS, without fear of disruption to the
caching/recursive machines.
