Reverse maps need to include at least a full class C subnet, yes, unfortunately.
It's because reverse lookups work by doing recursive lookups in the in-addr.arpa "special" domain.
Reverse looking up 127.3.4.5 will end up lookup up 5.4.3.127.in-addr.arpa.
The minimum reverse table you need to have is 4.3.127.in-addr.arpa.
