It is common practice to define them at top of the file. Also the AOSP
guidelines have it:
Well, now you might say that that is no reason but the thing is that
people are expecting them to be there and it makes it easier to read the
code for them if the things are in the familiar places.

No, I'm pretty sure my university network gives public ip addresses for
everyone connecting to their wifi.

I don't know what to do about this.
