Bind db.x configuration files

Question

Where can I find good, informative tutorial about configuration files in bind? I have these files (and other irrelevant ones):

db.0  db.10  db.127  db.255  db.empty  db.internal  db.local  db.root

I guess that db.10 works for IPs beginning with 10, and so on, but the internal structure of the file is quite unclear.

I have looked this up in Google and found very little reference to these files; Can anyone post a reference to a good source?

Thanks,

Udi

These are Bind Zone Files. DNS arranges data not by domain, but by zone; when it is presented to the client and processed, it is not by zone, but by domain. There is a distinct difference. You can read RFC 1035 and parts of RFC 1034 for more information.

I would recommend the "Grasshopper" book for further reading. It can be a bit dry at times, but the first 4 chapters are priceless and will expand your understanding of DNS in an appreciable way.
