Many ISPs and end-user firewalls seek to block bogons, because they have no legitimate use (more details on how successful they can be at this are below). But filtering the full bogon list requires about 5000 rules for IPv4 and about 70,000 rules for IPv6. Filtering private IP addresses requires only a few rules.

This issue should be rectified because: - Fragmented packets are often dropped by intermediate devices and firewalls. Last but not least, both IPv4 and IPv6 are available.

This is generally not an issue with modern hardware with multiple gigabytes of RAM TCP window scaling and selective acknowledgments may not be supported by some older firewall implementations. This is generally not an issue with current products from top-tier network vendors such as Cisco and Juniper. Have More Questions?
