Comment (by dd32):

 FWIW I don't see the need to to allow validation of only-ipv4, having it
 just specify `ip` and checking it's a valid IP seems the best way forward
 to me. If we can internally map `ipv4` to a generic `ip` check that seems
 even better.

 The only reason I would want a specific IPv4 validator is if the json
 schema spec followed doesn't allow a generic `ip` specification and wanted
 it to be specified as `[ 'ipv4', 'ipv6' ]`.

 As for validating IPv6 addresses, that's a super-complex regex AFAIK, we
 may be able to borrow/call/re-use something from `src/wp-
 includes/Requests/IPv6.php` / `src/wp-includes/SimplePie/Net/IPv6.php`
 though.
