Use nameserver name or IP?

Is there a generally accepted practice when it comes to
specifying nameservers? Specifically, in /etc/resolv.conf
files (for example) I normally use the IP form for the
nameserver. But, this makes it tricky to bring up or replace
the existing nameserver.
Another example might be in the name-server entry of DHCP
tables - use the IP or the FQDN?
Many sites seem to use names like ns1.domain.com and
ns2.domain.com which has the advantage that you can move
your name services to a new host/IP and as long as the name
is the same, all clients can use it.
I guess there is a slight overhead in using the FQDN form,
but is that a price worth paying for the management
