Abstract
Traffic is obtained from a plurality of internet protocol version six addresses within a plurality of internet protocol version six blocks; and a first indication of inappropriate traffic is obtained from a first one of the addresses. Responsive thereto, a reputation score for a first given one of the blocks, containing the first one of the internet protocol version six addresses, is incremented by a first predetermined amount; and a reputation score for an adjacent block is incremented by a second predetermined amount which is less than the first predetermined amount. Traffic from the plurality of internet protocol version six addresses within the plurality of internet protocol version six blocks is passed or blocked in accordance with a policy based on the incremented reputation scores for the first block and adjacent block. Techniques for internet protocol version four (individual and network address translation aspects) are also provided.
