Reverse zones best practices

[nex6]

Hi all,

look for some info on best practices for reverse zones. I have, a pretty big IP space and alot of reverse zones are not created.
I want to clean it up, a few people that dont really know DNS are thinking of "super netting" eg a top level 10.0.0.0/16 sorta thing. 

but we have 100s of defined mission critical reverse zones defined at the vlan level of 10.x.x.0/24...  my thinking, would be do a
discovery and create all the /24s, even if there is like 100s. instead of the bigger super net...


what would be the best practice and the way to go?
