Eric, is it a good idea to make this change separately? I think it is so
self-contained that it diserves its own separate CL.

[eroman, 2015/12/21 23:25:04]

Yes.
In fact a number of my recommendations make sense to do separately.

(For instance changing address() to return an IPNumber should definitely be its
own CL)

I have made it separately.  https://codereview.chromium.org/1540413002/.
Martijn, if want, you can take it from me.
