Do you only trust your own subnet? Or, perhaps there are other adjacent
subnets that may be needing to use your nameserver for resolving
Internet names (?)
The identity/size of the "allow-recursion" range needs to be informed by
your overall Internet-facing network topology. Talk to your network
architect if necessary to get the appropriate values.

Hey great thanks for the confirmation .. In that case I will change mine to
24 ... as that is my subnet mask
Thanks

/16 or /24 are ways to specify a network mask. Its called CIDR or classless
inter domain routing (I think that's the meaning) syntax and its pretty
easy.
/8 = 255.0.0.0
/16 = 255.255.0.0
/24 = 255.255.255.0
Those are the standard subnets, but others exist. Its very convenient for
cutting up IP ranges. Read on google.
