[expert] addition to hosts.deny?

[Mark Weaver]

Hi LIst,

I was wondering if anyone has either done this or knows if it's legal to be 
done. I want to list an entire net block in the hosts.deny file on my machine.

EX:

        ALL:224.0.0.0 - 239.255.255.255

Would the above be a valid entry in the hosts.deny file?

thanks,

Mark
