No, that is only a common but special case for hosts at the edge of a
network, such as a workstation. The most common exceptions to this
would be:
1) situations where I want my own DNS, not my providers
2) situations where I am sitting between 2 networks, which DNS field
should I take?
3) it is not required that DHCP provide me DNS fields - that is a
commonly configured field only
4) situations where I do not want DNS to preempt local sources like
FILES.
