IPv6 Primer for Deployments

Scott Lowe

This is a liveblog of the OpenStack Summit Sydney session titled “IPv6 Primer for Deployments”, led by Trent Lloyd from Canonical. IPv6 is a topic with which I know I need to get more familiar, so attending this session seemed like a reasonable approach. IPv6 was released in 1980, and uses 32-bit address (with a total address space of around 4 billion). IPv6 was released in 1998, and uses 128-bit addresses (for a theoretical total address space of 3.4

SD-WANs get IPv6 support from Versa

Network World

Software Defined Networking vendor Versa this week added support for IPv6 to its SD- WAN and security packages. According to Kumar Mehta , founder and CDO of Versa Networks by supporting IPv4 and IPv6 for SD-WAN and SD-Security, customers will have the flexibility to design their WAN under IPv4 today and protect it from obsolescence as they switch over to IPv6 in the future.

Interop Liveblog: IPv6 Microsegmentation

Scott Lowe

This session was titled “IPv6 Microsegmentation,” and the speaker was Ivan Pepelnjak. Ivan is, of course, a well-known figure in the networking space, and publishes content at [link]. The session starts with a discussion of the problems found in Layer 2 IPv6 networks. Note that some of these attacks are also common to IPv4 and are not necessarily unique to IPv6. The proposed solution suggested by Ivan is to move to Layer 3-only IPv6 network designs.

Bogons: Do not let them in or through your networks

CTOvision

With this post we will dive a bit deeper into bogosity in networks, paying particular attention to the fundamental element of bogosity, the Bogon. We will then articulate a use case for the Centripetal Networks RuleGate which can ensure bogons never get to your enterprise. But filtering the full bogon list requires about 5000 rules for IPv4 and about 70,000 rules for IPv6. Additionally, IPv4 networks are not safe from an IPv6 bogon bandwidth flooding attack.
