Bogon Address - What is ...

I was just going through the "Traffic Filtering" section. I came across this interesting attack of using a "Bogon" IP address.

"Bogon" is name for an IP packet on the public Internet that claims to be from an area of the IP address space reserved, but not yet allocated or delegated by the Internet Assigned Numbers Authority (IANA) . The areas of unallocated address space are called "bogon space".

Pretty neat huh ...

The following link from IANA shows the unassigned and unassigned IP4 address space.


So how do we filter it ? stayed tuned ...
