Your reverse setup is a mess. The delegation records in
218.194.203.in-addr.arpa. disagree with the ones in
0-255.218.194.203.in-addr.arpa., there is no zone
130-254.0-255.218.194.203.in-addr.arpa. (if there was, this would most
likely be a configuration error as well, since you cannot have a CNAME
pointing to a CNAME. RFC 2317 mentions this.) When asked about
130.130-254.0-255.218.194.203.in-addr.arpa. qtype=any, both published
servers return SERVFAIL status.
Also the zone name part '0-255' implies to me that the entire /24 is
convered; why not redelegate the parent in that case?
Go read RFC 2317, then tear your reverse setup down completely and
build it from scratch. It seems to me to be FUBAR.
