Abstract: Systems, methods, and computer-readable media for identifying bogon addresses. A system can obtain an indication of address spaces in a network. The indication can be based on route advertisements transmitted by routers associated with the network. The system can receive a report generated by a capturing agent deployed on a host. The report can identify a flow captured by the capturing agent at the host. The system can identify a network address associated with the flow and, based on the indication of address spaces, the system can determine whether the network address is within the address spaces in the network. When the network address is not within the address spaces in the network, the system can determine that the network address is a bogon address. When the network address is within the address spaces in the network, the system can determine that the network address is not a bogon address.

Abstract: In order to improve the locking of a bicycle which is provided with a bicycle lock with a built-in cable- or chain-lock (12), a lock according to the invention is configured in such a manner that the cable-lock (12, 14) can be locked only providing that the locking ring (6) is locked, and vice versa. The lock hereby affords better protection, the reason being that when the lock according to the invention is used, then both the lock's normal locking ring (6) as well as the cable-lock (12) have to be broken open. This is achieved by preventing the locking pawl (4, 33) from entering into a locking engagement with the locking groove (15) in the locking piece (14) unless the locking pawl (4, 30) is engaged with the locking groove (10) in the locking ring (6), and vice versa.

Abstract: This device is a bicycle lock that prevents unauthorized movement of a bicycle. The lock permanently fastens to the tubing of a bicycle frame and includes a locking bar which hooks the front or back wheels to the frame. The lock has two major parts--a combination or key lock and attaching saddle that permanently attaches to the bicycle frame, and, the locking bar or shackle. The saddle is positioned on the frame adjacent to the back or front wheel. The wheel holding part of the shackle hooks around the rim of either the back or front tire. The shackle part fastens into the saddle lock on the bicycle frame in alignment with the frame. This causes the wheel and the frame to be joined so that the wheel cannot be removed and the bicycle cannot be ridden. When the bicycle is unlocked, the locking bar is secured in a carrying position in which it cannot be jarred loose. A flexible cable may be used with the lock to attach the bicycle to a stationary object to render the bicycle immobile.

Abstract: At a swiveling stirrup lock, particularly for a two-wheel vehicle with a swiveling stirrup that can be swiveled through the spokes, the swiveling stirrup is supported in a swivel hub to be rotatable about its longitudinal axis. The swivel hub is supported to be swingable about a swivel axis on a pivot bearing which is to be attached at the bicycle frame. At least in the driving position, the swiveling stirrup is secured by engagement of a rotation securing element, installed at the swiveling stirrup, into a rotation securing element mounting of the pivot bearing. This engagement can be produced or released by rotating the swiveling stirrup into or out of a rotation securing position. The rotation securing element is installed according to the invention at the swiveling stirrup in the region of its outlet from the swivel hub outside the latter.
