What is Bogon IP Address and Bogus Space?

Bogon IP Addresses are the set of IP Addresses not assigned to any entity by Internet Assigned Numbers Authority (IANA) and RIR (Regional Internet Resgistry). This unallocated address space is called the bogus space. Bogons also include reserved private address and the link local address ranges (Martian Packets). IANA might assign Bogon IP addresses to an entity or RIR with the passage of time.

Here are the bogon IP address ranges:
