Internet Filtering Solution

the best solution that spings into my mind is to install squid [1] and 
squid guard [2]. squid is a proxy server and squid guard a redirector. 
with the latter you can prevent certain urls to be visited by certain 
users/user groups using blacklists that are available on the internet. 
However, setting the whole thing up requires some expertise.. :-/

another solution would be to blacklist or whitelist IPs using iptables, 
but I suppose that even more complicated as the such lists afaik don't 
exist for iptables.
