It's a little worse than that in this case; 194 isn't a provider block, it's one of the two superblocks in Europe, delegated to the RIPE NCC (the other one is 193).
The bogus info is actually in the zone files themselves, according to Lars-Johan Liman at KTH in Sweden (they run nic.nordu.net, one of the root servers). This means that all root servers will be infected -- I just checked three, and yep, sure enough.
Those root operators reading this, please consider fixing the zone file; the correct data is
194.IN-ADDR.ARPA. 518400 NS sunic.sunet.se. 194.IN-ADDR.ARPA. 518400 NS munnari.oz.au. 194.IN-ADDR.ARPA. 518400 NS sparky.arl.mil. 194.IN-ADDR.ARPA. 518400 NS ns.ripe.net. 194.IN-ADDR.ARPA. 518400 NS ns.eu.net. 194.IN-ADDR.ARPA. 518400 NS ns.uu.net. 194.IN-ADDR.ARPA. 518400 NS layon.inria.fr.
i've fixed this on ns.isc.org, though i'm not sure what good it will do unless all the roots do it.
