ARIN Enters Phase Two of the IPv4 Countdown Plan

That means only AfriNIC has plenty of addresses. If you love IPv6, now is your chance to stampede ARIN and claim all the IPv4 addresses you can. We won’t see any serious upgrading until the ipocalypse is forced onto everyone. Burn, waste and consume those IPv4 addresses, make the future brighter   ARIN now has […]

Update: IPocalypse: What’s next for the ‘End of the Internet’

On the 20 January 2011, I wrote about the “End of the Internet”. In Sep 2012, we are witnessing the ongoing apathy of IT managers and leaders to even discuss the problem. When it can be avoided, IT leaders will continue to ignore the problem and fail to plan for the future. This week, RIPE […]

Show 43 – Microsoft Teredo is Crap

A shorter show this week as Greg gets ready to go to Interop in Las Vegas next week courtesy of HP Networking. We look at recent events and talk generally about network with Tom Hollingsworth, Brandon Carroll and Greg Ferro.

Microsoft Teredo is a no-go area for IPv6.

I’ve talked before about Microsoft Teredo protocol for IPv6 tunneling and called it a bag of crap. Geoff Huston puts some solid information down about Teredo and why it should not be considered. My gut feeling : Teredo = NetBIOS (and we all know how that worked out) but Microsoft continues to develop it’s own proprietary technology and embed it into their products. Geoff Huston has some evidence about how bad it is.

Network Dictionary – Address Family Translation

Address Family Translation ( abbrev AFT) refers to the translation from one address family into another address family. For example, from IPv4 address to IPv6 address or vice versa. translation is sometimes denoted as NAT46 ( initiator from IPv4 side) or NAT64 (initiator from IPv6 side). AFT can be stateful or stateless. Stateless AFT is […]

Help: Got Questions for the NICs / RIRs about IPv6 ?

Slightly off topic, but I’m working with Skeeve Stevens to get some interviews setup for PacketPusherswith people from the various Network Information Centre (NICs) while they are at APNIC 31. I think there are lots of questions about public / Internet IPv6 and some early discussion of the issues would be useful, especially focussing on […]

Naming IPv6 address parts – Proposed IETF RFC and a VOTE

Some time ago I posted a word “chazwazza” to the Network Dictionary :Network Dictionary  Chazwazza. Although it was mostly intended to be a humourous comment, what makes it funny is that we don’t actually have a good naming convention for the ‘chazwazza’ of an IPv6 address. Apparently I’m not the only person to have noticed. […]

IPv6 Provider Independent Addressing is an IAB Recommendation

I’ve just been reading Russell Helling blog post – Fear and Loathing in IPv6 where he talks about gut reactions from the Service Provider side in Provider Independent (IPv4) address space. Go and read it.

The Importance of Provider Independent IPv6 Addressing

It’s important for people to apply directly to their registry for IPv6 address allocation. You should not get an allocation from your Service Provider.

TCAM – a Deeper Look and the impact of IPv6

The thing about TCAM memory is that it can be big killer for IPv6 migration. Why ?

Why Allocating a /64 is Not Wasteful and Necessary

Some discussion on why allocating a /64 is not wasteful

IPv6 – /48 allocation in /64 chunks – that’s a lot of addresses

I posted yesterday about changes to RFC3177 for IPv6 allocation. I wonder how many have done the maths on this and realised just how many addresses this works out to be. Lets hold hands and work through the maths: Lets say you are allocated a /48 by your favourite RIR. Lets also say you allocate […]

The IPocalyse is Nigh – Forced Allocation of IPv4 to RIRs next week ?

The whisper is that the last two /8 IP address ranges were today allocated. Since there were seven pools of /8 addresses, this means that we are witnessing the start of the IPocalypse. What’s Happened ? Some time ago, Internet Assigned Numbers Authority (IANA) established the final process as the IPv4 address pool is exhausted. […]

IETF IPv6 address allocation policy being updated.

IETF is now backtracking on /48 IPv6 address allocation by letting anyone do what the hell they like. Why not ?


Scheduling the IPocalypse

Ivan Pepelnjak has made a presentation available at [Slideshare - Content over IPv6 - No Excuses]. One slide particularly caught my attention: It’s timely reminder that the IPocalypse is going happen quite slowly. Each step is inevitable but none of the them are the final step. For example, once the IANA runs out of addresses, […]

Show 21 – IPv6 for the Win! Part 2

This week on the Packet Pushers podcast, Greg and Ethan continue an IPv6 technical deep-dive with Matt Ryanczak, Network Operations Manager at ARIN (where they’ve been running IPv6 since 2003) and Jan Bervar from NIL who has done several enterprise IPv6 deployments.

RFC 5952 – A Recommendation for IPv6 Address Text Representation

At last, some decent rules on the RIGHT way to write IPv6 addresses.
