    Default isn't quite correct here. More accurate is `Mesos will do a lookup 
of the machine's hostname to try and figure out what IP address to use`

    Please use <stdlib.h> or use the <c*> variants consistently

    Supersedes -> Overrides like you did in the docs?



src/master/main.cpp (line 211)

    Could you add a basic "Can we change this discoveredIp -> an actual IP 
address" check here?  The error message when LIBPROCESS_IP ends up incorrect 
inside libprocess is going to not say very cleanly where that value came from, 
and I suspect when doing iteration it will be fairly common for people to write 
IP scripts which give incorrect / invalid output.
