I would like to to start putting in firewall rules to block ANYTHING
from certain domain names.  For instance, I'll often get hit from
(something).sp.mandic.com.br, but there doesn't seem to be a contiguous
IP range.  I think I figured out that I need
        ipfwadm -I -a deny -S mandic.com.br
to do that.  will that block  (something).sp.mandic.com.br?

Also, how would I check it?  I've been trying variants of 
        ipfwadm -I -c -S (ip address) -W eth0
but whatever I try, I get one error message or another.

Thanks in advance.
