IPv4 and IPv6 Bogon Address List

“Bogon” or coined from the word “bogus”, In computer world,  these are IP addresses that have not been officially assigned to an entity such as IANA or Internet Assigned Number Authority which is an organization who managed allocation of globally unique IPs. 
Bogon IP adddress/ranges should not appear on the public Internet so network engineers should filter these as they are meant for use only in private networks  and considered reserved for special purposes.

You can refer to Team Cymru website who keeps an updated list of bogon IP addresses that you can use to put in your devices firewall or ACLs. Here’s a sample list of bogon IPs –> https://www.team-cymru.org/Services/Bogons/fullbogons-ipv4.txt

2 Types of Bogons:

  • Unallocated – not yet been assigned to an Regional Internet Registry (RIR) by IANA
  • Martians – private networks as indicated in RFC1918, reserved address like loopback and multicast.

Here are sample Bogon netblocks and the list is constantly changing.
