>Correct, because neither one of those follows the example of using a range you yourself already provided. Re-read the example of a range you provided above. See how you specified a range for 188.8.131.52 to 184.108.40.206? That used a CIDR block. Additionally you can use a netmask. See the docs.
>Note, that since the above range you're trying to deny isn't expressible using a single netmask. That leads me to question if indeed that's really the range you wanted since you're not describing a network anyway. If indeed it is the range you wanted, break it down into two (or more) CIDR blocks according to the networks you're trying to represent.
Good call, Dan.
Steve at al, here's a handy little CIDR calculator, I've used this a lot for configuring Postfix blocks:
hope this helps.
10 days to Hallowe'en! woo hoo!
