For non-default setups, certainly.  Default for CPEs needs to be "fully
automatic, with prefix delegation", unless it is known for sure that there
is no prefix delegation in that particular environment (like: the CPE
has no "LAN" links of any sort, by being a node with just a single network
interface, or being just a host without routing functionality).
