Here or there, you can read configuration files named like db.192.168.42

For networks with a /24 mask, simply striping ending 0/24 substring from
192.168.42.0/24 is enough.
But what about network with a different prefix ?

1. How can you compute this "db.192.168.whatever" from 192.168.x.y/z
network address ?
better set up reverse zones 192.168.0, 192.168.1 etc.
the RFC above should be only used for <24 ranges.
Example in Python would be appreciated.
2. Instead of using short "db.192.168.42" names, I used a long
"db.192.168.42.0". I didn't notice any issue. Did I overlooked something ?
it's just a file name. You can use "myrevzone" as long, but using
db.192.168.42 is much more explanatory.
