Comment (by azaozz):

 @iandunn thanks for the review and the fixes! 43545.5.diff looks good.
 Going to commit it later today if no other remarks.

 the un-anonymized IP is going to cause GDPR issues.

 Was thinking about that too. For privacy we have to guarantee we return an
 anonymized IP, no matter what. Since we depend on the PHP
 version/environment to be able to do anonymization of IPv6 addresses, it's
 probably a good idea to be able to fall back gracefully. However removing
 that will make `wp_privacy_anonymize_ip()` simpler to use... Kind of 50/50
 there :)

 No problems with new files in /tests. They are only problematic in /build
 for minor releases.
