as far as I can see that is reported as a warning only. However, the reference
to RFC 1912 is a bit outdated. There's a wg action item 48.3 (see action list
at http://www.ripe.net/ripe/wg/dns/action-list.html) already to document,
evaluate and replace as necessary the currently applied tests. Your suggestions
are welcome.

RIPE 203 aims at "small and stable" zones. Not all IN-ADDR.ARPA zones do
fall into this category. The values suggested there may still be applicable
to many IN-ADDR.ARPA zones, but that depends.
