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.

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.

   IPEndPoint(const IPEndPoint& endpoint);
 
   const IPAddressNumber& address() const { return address_; }
