 From a DNS perspective the block size of 4 (or 8 for IPv4) absolutely 
makes
sense, but having the option to provide the CIDR with any figure (as 
comon
on routing) would be great. Thanks for pointing out the issue.

I have added the address with four /12 networks:
rev-server=fe80::/12,192.168.178.1
rev-server=fe90::/12,192.168.178.1
rev-server=fea0::/12,192.168.178.1
rev-server=feb0::/12,192.168.178.1
