Just been reading up on IP tables, but so far have seen nothing to
address a large list. So far my searches on tcpwrappers has not revealed
much insight.
For example, at:
http://www.cyberciti.biz/faq/how-do-i-block-an-ip-on-my-linux-server/
In order to block an IP on your Linux server you need to use iptables
firewall. First you need to log into shell as root user. To block IP
address you need to type iptables command as follows:
iptables -A INPUT -s IP-ADDRESS -j DROP
Replace IP-ADDRESS with actual IP address. For example if you wish to
block ip address 65.55.44.100 for whatever reason then type command as
follows:
# iptables -A INPUT -s 65.55.44.100 -j DROP
This is limited to one IP at a time (apparently). The page then goes
from this to even more specific (limited) help. Having got the list
already, do you know if some variation of this could be used to apply it?

Good advice is like good paint- it only works if applied.
