Bogons
Bogon networks:
We are proud to announce new updated CIDR and Netmask Bogon Lists. Our new Bogon database contains information on Reserved and Special Use Network space. This data includes Reserved Networks typically considered Bogons, plus Private Networks, Loopbacks, Auto-configuration ranges and Multicast network space. Bogon addresses are network ranges reserved but unallocated and usually have no business entering your network from outside your network boundaries.
For more bogon formatting choices please select a format using the form on the right sidebar, then select bogons from the list.
