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?

Liveblog: IPv6 in the Cloud - Protocol and Service Overview

Scott Lowe

This is a liveblog of an AWS re:Invent 2017 breakout session titled “IPv6 in the Cloud: Protocol and Service Overview.” Halachmi starts the session promptly at 11:30am (the scheduled start time) by reviewing the current state of IP4 exhaustion, then quickly moves to a “state of the state” regarding IPv6 adoption on the Internet. Global IPv6 adoption is currently around 22%, and is expected to hit 25% by the end of the year.

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. I believe you can have both IPv4 and IPv6 as dynamic and things will "warn" you but not break. SeanDaniel.com [tech].

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.
