- Removal of multihomed requirement for IPv6 PI — RIPE Network Coordination Centre –
Removal of multihomed requirement for IPv6 PI
12 Apr 2011
Summary of proposal:
This proposal intends to remove the multihome requirement necessary to receive PI IPv6 address space in the policy ripe-512, “IPv6 Address Allocation and Assignment Policy”.
There are enough End Users (businesses) that have a valid reason for their own address space, without the desire to become a LIR or multihoming.
I wrote about why this is vital http://etherealmind.com/importance-provider-independent-ipv6-addresses/. Common sense prevails.
- Cisco is SCARED! Why Cisco won’t release an emulator. « subnetwork –
I know what you’re thinking. “They don’t have anything to be afraid of. That’s crazy talk.” I’m sure that people said the same about Dell and HP when ESX was first announced. “They don’t have anything to worry about. No data center could ever virtualize all of their servers. That’s just crazy.” Only, it did happen. Right now I am sitting just a few hundred feet from 100 servers that would be over 500 servers if it wasn’t for vmWare. Think of the lost revenue to Dell and HP.
Interesting take, could be a viable reason.
- Coding Relic: Random Early Mea Culpa –
Instead of describing RED as a feature to control congestion in the network, we described it as a feature which would deliberately drop your packets. I attribute this to the same attitude which made ASIC designers want to hold onto the packets which had already been stored in the buffers. We made RED sound like a dangerous thing, which you should only use if you know exactly what you're doing and also have some very special network with obscure requirements.
Must read. Go now.

….armoured underpants…. ppffft, snigger.
- As PlayBook Launches, Cisco’s Cius Slowly Emerges CIO.com – Pretty sure that the Cius needs to die as well. If it's all about the video, it's won't be successful either.
Cisco is aiming the product at business collaboration, with the ability to interoperate with the company's TelePresence videoconferencing system, the Cisco Quad and Cisco Show social-networking platforms, and the company's WebEx online meeting system. The Cius, which is based on the Android 2.2 operating system, is also designed to run business applications.
- Key Turning Point in Asia Pacific IPv4 Exhaustion
APNIC – IPv4 “Final Stage” Begins Today – As predicted, APNIC has started rationing it's final /8. Remember, APNIC has more demand for IP addresses than any other region.
This event is a key turning point in IPv4 exhaustion for the Asia Pacific, as the
remaining IPv4 space will be ‘rationed’ to network operators to be used as essential
connectivity with next-generation IPv6 addresses. All new and existing APNIC
Members who meet the current allocation criteria will be entitled to a maximum
delegation of a /22 (1,024 addresses) of IPv4 space
- Cisco IOS Hints and Tricks: vCloud Director Networking Infrastructure (vCDNI) scalability – The VMware vCloud virtual networking feature is high risk implementation that is vulnerable to simple broadcast storms. Ivan looks at why:
As always, we prepared a few questions in advance, including “How are broadcasts, multicasts and unknown unicasts handled in vCDNI-based private networks?” and “what happens when a single VM goes crazy?” For one reason or another, the podcast never happened. After analyzing Wireshark traces of vCDNI traffic, I probably know why that’s the case.
