Bogon networks
A bogon network is a range of IP addresses that are otherwise known as bogon addresses, those defined as Martians (private and reserved addresses defined by RFC 1918, RFC 5735, and RFC 6598) and netblocks that have not been allocated to a regional internet registry (RIR) by the Internet Assigned Numbers Authority.
Bogon IP addresses can, not entirely accurately, be thought of as fake IP addresses. The bogon IP space not assigned to any entity by Internet Assigned Numbers Authority (IANA) and RIR (Regional Internet Registry) may be as of yet unassigned or may be specially reserved for private network use. Addresses reserved for private networks, such as those in 10.0.0.0/8, 172.16.0.0/12, and 192.168.0.0/16 are considered bogon. Local machine loopback addresses like those in 127.0.0.0/8 and link-local addresses like 169.254.0.0/16 are also bogon.
