Complete Bogons List

Press Release:

January 8, 2012

Country IP Blocks is proud to announce that we will now include the complete list of all Bogon networks within our database (this includes IPv6 networks). Bogons are networks that are reserved, or allocated to a Regional Internet registry but unassigned. Bogons should not generally be allowed access to your inbound networks.

A bogon is a bogus IP address, and 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 the bogon space. Source.

The addition of the complete bogon and unallocated networks to our database means we have 4,294,967,296 IPv4 addresses or 100% of all possible IPv4 addresses. These addresses are updated daily

Proper filtering of Bogon traffic may reduce malicious traffic by 10% to 60% on your network.

If you are going to filter Bogon traffic please keep in mind these networks change daily. Therefore we recommend you develop a plan for maintaining your Access Control Lists and update them often. Failure to do so could result in undesired results.
