European IP regulator RIPE NCC has made available two of the IP blocks seized by the FBI and the Internet Systems Consortium during DNS Changer incident last month. The IP ranges were controlled by FBI as per the US court order to prevent a blackout for the infected PCs. After the expiration of the court order, they have been quarantined, but they`re now back in business with new owners. The re-introduction of these IP ranges can hardly be regarded as standard procedure and might carry risks for the new owners.”]
