Hey
  Have a look into /etc/hosts.deny
  There is a man page for it that describes the syntax which includes IP/mask and FQDN. e.g.:
sshd: .au 192.168.1.0/24 *owen*
  This would block all domain names ending in .au, the IP range 192.168.1.x and any domain name with 'owen' in it.
  An alternative would be to use 'sshd: ALL' in hosts.deny and selectively open access using hosts.allow


cheers,
Owen.
