I'm not tied to the prose I wrote, but I would like to see the description expanded to clarify the issue.
I only changed a string. I only tested it as far as ensuring that it didn't cause a syntax error.
The new description should give more clear understanding of when to edit the option. I used NixOS to set up a DNS server that is authoritative for certain zones. The description of the `cacheNetworks` option made me think I needed to set it to `"any"` to allow people to query the zone I set up. Reading the source of the module would have clarified my understanding, but at the time I just read the description and thought little of it. Later I discovered I was getting tons of DNS requests and presumably being used for a DNS amplification attack or similar. I have fixed the problem now, but I would like the option to have a clearer description so others don't make the same mistake I did.
