answers, for SRV record, DNS update, or anything that is only supported =
by newer version of BIND?

The DNS servers they obtain through DHCP (or pre-configured in=20
their /etc/resolv.conf, or other client equivalent) should be=20
recursive/caching servers, so that the clients can obtain information=20
about other machines on the Internet, etc.... DDNS is important on=20
authoritative servers, which would be providing information *about*=20
the clients, to other machines on the Internet.
For various reasons (including security), the caching/recursive=20
machines and the authoritative machines should be two separate sets=20
of systems. Therefore, you should be able to update the=20
authoritative machines to use DDNS, without fear of disruption to the=20
caching/recursive machines.
