Details

The CUII (Clearingstelle Urheberrecht Im Internet) is the german Clearinghouse Copyright in the Internet.

It is a self-controlled private organisation using DNS-Hijacking for fighting copyright violation in the internet in Germany.

The CUII consists of these groups of members:

• Copyright holders / license distributors recommending domains to block
• A private and secret circle of people deciding what will be blocked
• ISPs performing the blocking through DNS-Hijacking

They maintain a confidential list of Domains to block, which the participating ISPs hijack to an IP under CUII control.
For clients of the participating ISPs a HTTP request to one of the blocked Domains resolves to notice.cuii.info.

While the CUII keeps the blocking list confidential there are partial leaks to Wikipedia and more verbose to cuiiliste.de.
cuiiliste.de is a third party project where germans can test their ISP and report previously unknown blocked Domains.

So far all known blocking covers copyright violating Domains, many of which just are prominent URL collections.
In Germany an URL to illegal content may be treated the same illegal as the referred content itself.

This simplifies censoring, They do not have to block the numerous hosters of illegal content, just the most prominent index.
