Re: How to block a range of IP's?

Jefferis Peterson asked:

I'm trying to block a range of IP's
[snip]
I'd like to create this with the least amount of hand coding.  Your first
suggestion would seem to block too many.  How would you set a range block
for the 3rd set of numbers below?

 * ^Received: from.* 209\.163\.96-111\....
 
Is it possible? 

I presume you're looking for something like this:

  * ^Received: from.* 209\.163\.(9[6-9]|10[0-9]|11[01])\....
or
  * ^Received: from.* 209\.163\.(9[6-9]|1(0[0-9]|1[01]))\....

(I'm not sure whether it's more efficient to "factor" out the 1
as in the second example, but I'm sure someone will chime in.)

Hope that helps,
Stan
