Each Regional Internet Registry ("RIR") receiving notice of this Order shall take all steps necessary to prevent and prohibit the defendants and their co-conspirators from: a. effectuating any change of control over the current registration accounts for the Target IP Addresses; b. making any changes to the registration records for the Target IP Addresses unless prior authorization is received from the FBI, or the United States Attorney's Office for the Southern District of New York ("USAO-SDNY"); or c. directly or indirectly attempting to transfer the Target IP Addresses to any other individuals or entities, except as approved by the FBI, or the USAO-SDNY. [...] IT IS FURTHER ORDERED that: 15. this Protective Order shall be binding upon the defendants, their attorneys, agents, and employees, and all persons in active concert or participation with any of the above, all institutions described herein, or any other person having actual knowledge of this Order, and that this Order shall remain in effect until further order of this Court; [....] -- James S.
