On most devices of interest, this is a non issue; they are small embedded
devices, like phones.
For other situations, for example a sip softclient running on a laptop, we
will specify an api on the O/S the application is running. The api will
front end a set of "Location Configuration Protocols" of which DHCP is one.

But how does my application access it?
DHCP is not something that an application layer program should be allowed
to perform. It is a security issue. For good reason performing DHCP
operations requires privileges beyond mere network connectivity on
Windows.
That is why configuring application programs from DHCP never caught on.

The reason that DHCP is appropriate for information about the
location of the host is that the scope of DHCP administration
usually does match the local network to which the host is
attached. Location is local information.

What we (strive to) consider instead is the administrative scope of
the configuration information, and wether it matches common and
practical use of DHCP.

DHCP is a technology that dynamically configures hosts.
If a host has a configuration knob that might reasonably
and properly
be set by the systems administrator or the network you are
presently
attached to, then it is reasonable and proper to configure it via
DHCP.
