Network design, architecture, thinking, working. Tech.
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.
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.
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.
Some discussion on why allocating a /64 is not wasteful
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 [...]
So we are waiting for confirmation from IANA, but here is a bit of background.
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 is now backtracking on /48 IPv6 address allocation by letting anyone do what the hell they like. Why not ?
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, [...]
