Note that the target server of a forward zone should offer recursive
service. You will have problems if the target is authoritative-only, and
serves the zone you are forwarding but not some child zone. Better to use
static-stub in that case; that makes BIND do normal iterative resolution
except it overrides the NS records for just that zone, not its children.

(We make our recursive servers authoritative for our zones to avoid
problematic dependency cycles - the kind of horror you find out about
when trying to recover from a power outage.)

Rough or very rough, occasionally moderate later. Showers. Good.
