Also, once you are happy with your changes, make sure to save them so that they will be persistant across rebooting with: service iptables save

You can add those dynamic ips to the hosts.deny too but what is the point of blocking dynamic ips ? That's the question ?

Caveat with using tcp_wrappers (hosts.allow/deny) is that it only works for daemons that have support for libwrap. Not all do (Apache, Postfix and others do not) so make sure to check the docs to verify whether hosts.deny can do what you want.
