Hi all, I appreciate many people gave me advices, Some of persons asked me about my questions, I'm sorry for that I couldn't reply to everyone. Because of your help, I could get many opinions and standards regarding IP allocation policy. by the way, in APNIC's IP allocation sizes policy, there is a comments like below. "Below are the minimum sizes for allocations and assignments, This information is provided at the request of the ISP community to assist in filtering policy decisions " Currently, is there any provider filtering routes under LIR's minimum allocation size such as /22 ?

Dear Colleagues, The Internet Society has announced that it is seeking applications for the next round of the ISOC Fellowship to the IETF program, part of its Future Internet Leaders program (www.isoc.org/leaders) The program offers engineers from developing countries fellowships that fund the cost of attending an Internet Engineering Task Force (IETF) meeting. As you know, the IETF is the Internet's premier standards-making body, responsible for the development of protocols used in IP-based networks. IETF participants represent an international community of network designers, operators, vendors, and researchers involved in the technical operation of the Internet and the continuing evolution of Internet architecture. Fellowships will be awarded through a competitive application process. The Internet Society is currently accepting fellowship applications for the next two IETF meetings: * IETF 76 being held in Hiroshima, Japan, 8-13 November 2009 * IETF 77 being held in Anaheim, USA, 21-26 March 2010 Up to six fellowships will be awarded for each IETF meeting. Full details on the ISOC Fellowship to the IETF, including how to apply, are located on the ISOC website at : http://www.isoc.org/educpillar/fellowship Fellowship applications for both IETF meetings are due by *31 July 2009*. The Internet Society formally launched the ISOC Fellowship to the IETF program in January 2007 after successfully piloting the program during 2006 at IETF 66 in Montreal and IETF 67 in San Diego. Forty seven individuals from 29 countries have participated in the program since its inception. I encourage you to pass information about this program to individuals involved in your regional operators' groups that have a keen interest in the Internet standardisation activities of the IETF. You also may consider being a reference for the applicant. If you have questions, please do not hesiate to contact Connie Kendig <kendig(a)isoc.org> or Mirjam Kuehne <mir(a)isoc.org>.

All - Forwarded with permission. I think that Jonathan was actually commenting on two aspects that make the Internet model unique, one of which is the innovative nature of peering relationships and the second is the sense of a shared interest in the health and safety of global routing which is reflected in responses to network issues. NANOG is a part of both these forms of "goodness". - Lucy ---------- Forwarded message ---------- Date: Fri, 24 Jul 2009 09:54:39 -0400 From: Jonathan Zittrain <zittrain(a)law.harvard.edu> To: lynch(a)isoc.org Subject: Re: 5 forwarded messages... Lucy, Thanks for forwarding. It's not easy to compress the details of Internet routing (including BGP) into a short talk for laypeople, and going from that to a news article is even more lossy. Here's the context in which I brought it up: the Internet is not the only way to build a global data network, and its differences from other models, literal and metaphorical, are notable. The protocols themselves were in large part developed without the standard attempts to profit from them -- a case of the "patent that never was," as some have also called the Web. The daisy chains (daisy webs?) of routing are not, to me, functionally equivalent to the transitivity of contracts that make the international postal system flow, because of the ways in which new ISPs and ASNs can come and go, and overlap one another. There is a generativity to the network that has allowed for the kinds of innovation that simply haven't happened in more closed (and, some would say, rational) means of networking. I'm sure my view here is colored by my longtime experience with CompuServe, and the near-universal view I perceived among its engineers and sysops in the mid-80's that tomorrow's global network would be the winner of the grudge match among them, the Source, Prodigy, AOL, etc., not the backwater Internet. On the "volunteer" label -- I did not mean that members of NANOG (or the broader network community) are unemployed, or even employed only in unrelated fields. Instead, I wanted to say that when an incident like the YouTube/Pakistan situation comes up, there are people working together to solve it who don't owe YouTube a thing, and that aside from (re-)advertising its own equally or more specific route to itself, YouTube was not particularly privileged to fix the blackholing. It required people to help each other sort out the competing claims, and then favor YouTube's claim over that of AS17557. So, as I understand it, current routing implementations entail certain systemic vulnerabilities for which the YouTube incident is a good example, and when risks materialize they're dealt with in a kind of ad hoc fashion that relies on a lot of cooperation, and not necessarily among contracting parties. I see similarities to the ways Wikipedia governance works, but that's probably flamebait for another time. Anyway, as the clueless country lawyer, I'm anxious to know what I'm missing or getting wrong or imprecise.

Blocking IPv6 broadcast
by Sharef Mustafa 23 Jul '09

23 Jul '09

Hi, I have a customer connected to my Cisco 3560 switch via Gigabit Ethernet, recently I noticed that he is broadcasting IPv6 packets such as LLMNR, DHCPv6 and ICMPv6 it seems that the customer is connecting a Vista machine that has some IPv6 services enabled (some IPv6 services are enabled by default on Vista) How can I block such broadcast from entering my network? By the way there is no firewall in this setup, just a switch to switch. BR Sharef
