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

Interop Liveblog: IPv6 Microsegmentation

Scott Lowe

This session was titled “IPv6 Microsegmentation,” and the speaker was Ivan Pepelnjak. 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 challenge with some of these fixes is that IPv6’s extension headers—which come before TCP or UDP header—can sometimes be manipulated to bypass such protections. Can we use shared Layer 3 IPv6 subnets?

Here’s an interesting article on the role that virtualization is playing in the network functions virtualization (NFV) space now that ARM hardware is growing increasingly powerful. Welcome to Technology Short Take #84! This episode is a bit late (sorry about that!), but I figured better late than never, right? OK, bring on the links!

Psst, hey Frank: “Mac” is the hardware from Apple, “MAC” is an acronym that stands for Media Access Control (in networking circles, as in “MAC address”) or “Mandatory Access Control” (in security circles).

I’m not sure if this falls here or into the “Cloud Computing/Cloud Computing” category, but Shannon McFarland—fellow co-conspirator with the Denver OpenStack Meetup group—has a nice article describing some design and deployment considerations for IPv6 in the OpenStack Kilo release. Servers/Hardware. I suppose this could go under “Networking”, but it’s really focused on hardware—specifically, the NoviSwitch line of OpenFlow-optimized switches from NoviFlow.

Bluetooth devices that don’t rely on bridges, such as Eve’s line of security and sensor products, will need hardware upgrades, meaning older devices won’t be compatible. IPv6 carries a heavy software burden and the majority of Zigbee devices out there could not support [that],” says Klein.

Amazon EC2 Cluster GPU Instances - All Things Distributed

The early GPU systems were very vendor specific and mostly consisted of graphic operators implemented in hardware being able to operate on data streams in parallel. Programming the GPU evolved in a similar fashion; it started with the early APIs being mainly pass-through to the operations programmed in hardware.

I'm wondering if it could be an adapter (hardware) issue. Installation of the DHCP role is straightforward enough until the question of IPv6 is raised. I'd assigned a static IPv4 address to the single NIC on the SBS2011 server prior to installing the DHCP role, but I have to admit that I skipped making any changes to the IPv6 config and therefore it was still set to dynamic when the role was installed.

A MAC Address is the hardware address of the local network card. The address listed is actually your ipv6 ip address. A MAC address looks like "00:00:1F:12:82:92" whereas an IPv6 address looks like "fe80:3615:9eff:fe09:94" To get your MAC address just type "ifconfig | grep ether" If more than one is listed then generally speaking the first one is if you're using a wired network connection and the second is a wireless connection.
