[expert] IP ranges

[Michael D. Kirkpatrick]

I am using squid and I have found that I am doing something wrong with
assigning
IP ranges.  All the examples show complete class C ranges.  Example:
192.168.0.0 - 192.168.0.255 would be entered as one of the following:
192.168.0.0/24  or
192.168.0.0/255.255.255.0

Now, I just want IP ranges of
192.168.0.0 - 192.168.0.99
192.168.0.111 - 192.168.0.255

I tried the following:
192.168.0.0/192.168.0.99
192.168.0.111/192.168.0.255

That does not work...  Any suggestions?
