Your provider also needs to add CNAMEs to their /24 reverse zone, e.g.
111.111.111.in-addr.arpa, for each address in the range, pointing at the
corresponding PTRs in your zone.
E.g. 2.111.111.111.in-addr.arpa in their zone needs be a CNAME pointing to the
2.0/27.111.111.111.in-addr.arpa PTR in your zone.
Note that the $GENERATE master-file directive of later BIND versions was
created to facilitate exactly this kind of thing.
