It is on purpose not too easy to remotely configure the network
settings of a computer, of obvious security concerns.

You could plant a script on the remote computer so that the
script runs ifconfig and route (or just ip) with the proper
parameters.

Directly from C code, the network settings are set with suitable
ioctl() system calls. For details, see the sources of ifconfig
and route. I'd advise against this kind of approach.

Would you please tell what you're attempting to achieve with
such remote network set-up and configuration?

I have an itch that you're attempting something that should
not be done in that way.
