To completely block an IP# from a server you'll need to use your firewall.

To block IP#s for specific services that are either managed by inetd or xinetd, or which have support for "hosts" compiled in, then you can use /etc/hosts.allow and /etc/hosts.deny.

The "man" manual system is your friend:

man hosts.deny

man hosts.allow
