An active magnetic bearing includes a bearing housing, a bearing stator, a bearing armature, a position detector, a jacket, and a stress buffering member. The bearing stator is accommodated in the bearing housing to support rotation of a rotor by using a magnetic force. The bearing armature is disposed to be spaced apart from the bearing stator by an interval and fixed to the rotor. The position detector is installed in the bearing housing to detect a position of the rotor. The jacket is interposed between the bearing stator and the bearing armature to seal a space between the bearing stator and the bearing housing. The stress buffering member connected to opposite ends of the jacket and the bearing housing, to buffer a stress generated due to differences between thermal exposition coefficients and temperatures of the bearing housing and the jacket.

Provided is a method for tracing-back an IP using marking information of a router stored on a hop-by-hop option header, which is one of IPv6 extension headers. According to the method, an attack made by an attacker is detected on the IPv6 network. If the attack is detected, information stored on a hop-by-hop option header of a packet received through the IPv6 network and marked by a router through which the packet has passed is extracted. After that, a reception path of the received packet is reconstructed and an IP of the attacker is back-traced using the extracted marking information.
