Here or there, you can read configuration files named like db.192.168.42 when holding data for a 192.168.42.0/24 network. 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. -- Matus UHLAR - fantomas, uh...@fantomas.sk ; http://www.fantomas.sk/ Warning: I wish NOT to receive e-mail advertising to this address.
