The 2011 Rocky Mountain IPv6 Summit was held in Denver earlier this week (25-27 April) at the Grand Hyatt. It was a great event, as we have come to expect from the Rocky Mountain IPv6 Task Force. I was especially pleased that they stepped the presentation content up a notch with regard to technical depth [...]

Day One: Advanced IPv6 Configuration is a sequel to my first book, Day One: Exploring IPv6, and picks up right where it left off. Namely with BGP. In addition to a fairly thorough look at BGP (iBGP and eBGP / native IPv6 peering and sharing IPv6 routes over IPv4 peering), the book jumps into a few of the additional and often overlooked aspects of deploying an IPv6 network. This includes a look into topics and tools including VRRP, ICMPv6 rate limiting, CoS, IPv6 path MTU discovery, DHCPv6, zero hop-limit, Multicast Listener Discovery (MLD) and Duplicate Address Detection (DAD).

I just sat in on a call/talk/presentation by Leo Vegoda (the guy who operates the IANA for ICANN) on IPv6. Overall, it was a great primer on IPv6, the exhaustion of IPv4 and the future of Internet addressing. One idea that I would especially like to echo here is his suggestion for everyone to send [...]

Before we look at what breaks, I should probably make sure that you know what it is that I’m talking about here. If you already know all about traditional NAT and address overloading, skip to the NAT444 section. If you are familiar with that as well, feel free to skip right to the list of [...]

Not overly surprisingly, APNIC officially received two more IPv4 /8 (“slash eights”) from the IANA today: Hi, The IANA IPv4 registry has been updated to reflect the allocation of two IPv4 /8 blocks to APNIC in January 2011: 39/8 and 106/8. 39/8 APNIC 2011-01 whois.apnic.net ALLOCATED 106/8 APNIC 2011-01 whois.apnic.net ALLOCATED [...]

I was planning on writing this great breakthrough piece on IPv6 subnet sizes, like how many /48s are in a /32 or how many /56s are in a /24, etc… But then I stumbled across a great PDF from ARIN and realized that all the work was already done. So I ended up not posting [...]

There are folks who have, in the past, cried wolf with regard to IPv4 free pool depletion and the need for IPv6 adoption. Different people had different reasons for doing so and some were likely ulterior. Since then, all of the reputable folks focusing on IPv6 deployment have removed these alarmists and distanced themselves from [...]
