I read through the updated API/javadoc. Just a few comments:

- the class description still links to the no-arg factory methods
- the @implNote says that only IPv4 is supported so I assume the notes 
can be removed now
- we should probably specify NPE for the corner case that family is 
null. A paragraph in the class description or @throws NPE in the 4 
methods is okay, either approach will do

I don't see any other issues with the API.
