ISDB Bogon IPv4 Address Object

hi,

i'm trying to create a FW policy in FMG to block "bogon" ipv4.

i just saw RFC1918 address FW address object but there's none for "bogon".

does fortinet considering to add these address space in a group/address object in future upgrade?

can someone also confirm these are true bogon IP ranges? just want to ensure i don't block "legit" traffic/range.

Hi @johnlloyd_13 ,

 

First of all, we need to understand:

What is a bogon address?

Bogon” is an informal 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) or a delegated Regional Internet Registry (RIR). The areas of unallocated address space are called “bogon space”. 

 

So Fortinet is not the authority to confirm what the bogon spaces are.  You have to contact IANA or RIR.

 

You may also use this form to request to add a Bogon space ISDB object:
