Back hoes, tsunamis, earth quakes, ship anchors and now 75 year old women with spades. Moral of the story....have another cable and not next to the one that the old lady will get to. It's interesting that the article indicates that the cable is heavily protected but apparently not from "spade hackers" Raymond Macharia On 7 Apr 2011 05:05, "Suresh Ramasubramanian" <ops.lists(a)gmail.com> wrote:

Fwd: IPv4 Address Exhaustion Effects on the Earth
by Joao C. Mendes Ogawa 06 Apr '11

06 Apr '11

FYI --Jonny Ogawa ----- Forwarded message from Stephen H. Inden ----- From: Stephen H. Inden Subject: IPv4 Address Exhaustion Effects on the Earth Date: Fri, 1 Apr 2011 00:19:08 +0200 To: Global Environment Watch (GEW) mailing list X-Mailer: Apple Mail (2.1084) X-Mailman-Version: 2.1.9 List-Id: "GEW mailing list." IPv4 Address Exhaustion Effects on the Earth By Stephen H. Inden April 1, 2011 At a ceremony held on February 3, 2011 the Internet Assigned Numbers Authority (IANA) allocated the remaining last five /8s of IPv4 address space to the Regional Internet Registries (RIRs). With this action, the free pool of available IPv4 addresses was completely depleted. Since then, several scientists have been studying the effects of this massive IPv4 usage (now at its peak) on the Earth. While measuring electromagnetic fields emanating from the world's largest IPv4 Tier-1 backbones, NASA scientists calculated how the IPv4 exhaustion is affecting the Earth's rotation, length of day and planet's shape. Dr. Ron F. Stevens, of NASA's Goddard Space Flight Center, said all packet switching based communications have some effect on the Earth's rotation. It's just they are usually barely noticeable. Until now. "Every packet affects the Earth's rotation, from a small ping to a huge multi-terabyte download. The problem with IPv4 is its variable length header and tiny address space that can cause an electromagnetic unbalance on transmission lines. The widespread adoption of Network Address Translation (NAT) on IPv4 networks is making the problem even worse, since it concentrates the electromagnetic unbalance. This problem is not noticeable with IPv6 because of its fixed header size and bigger 128 bits address space", Dr. Stevens said. Over the past few years, Dr. Stevens has been measuring the IPv4 growing effects in changing the Earth's rotation in both length of day, as well as gravitational field. When IPv4 allocation reached its peak, last February, he found out that the length of day decreased by 2.128 microseconds. The electromagnetic unbalance is also affecting the Earth's shape -- the Earth's oblateness (flattening on the top and bulging at the Equator) is decreasing by a small amount every year because of the increasing IPv4 usage. The researcher concluded that IPv4 usage has reached its peak and is causing harmful effects on the Earth: "IPv4 is, indeed, harmful. Not only 32 bits for its address space has proven too small and prone to inadequate solutions like NAT, it is now clear that its electromagnetic effects on the Earth are real and measurable." The solution? "I'm convinced that the only permanent solution is to adopt IPv6 as fast as we can", says Dr. Stevens. --

Alternatives to GSLB ?
by Jeff Blaum 05 Apr '11

05 Apr '11

Greetings, my company has application servers in several strategic locations throughout the globe. We're currently doing GSLB with a handful of BIND DNS servers, that return the A records of the closest server(s), based off of the IP address of the resolver doing the lookup for the client. GSLB obviously has caveats in this regard, and we are looking for ideas on how to 1) ensure clients are routed to the closest geographical server 2) ensure the client hits the server(s) with the shortest path. Any feedback would be appreciated. Thanks! Jeff

Re: HIJACKED: 148.163.0.0/16 -- WTF? Level3 is now doing IP hijacking??
by Jason Pope 05 Apr '11

All, WRT the below route object, DataBank does announce IP space for Hoechst Celanese Corporation as they are a direct customer of ours: > $ whois -h whois.radb.net 148.163.0.0 > route: 148.163.0.0/16 > descr: /16 for Celanese > origin: AS13767 > mnt-by: DBANK-MNT > changed: jpope(a)databank.com 20090818 > source: LEVEL3 > Currently, we only announce/originate the following prefixes via BGP: 148.163.178.0/24 148.163.179.0/24 via our providers, Level3 and Sprint. We asked our providers to relax their filters for the whole /16, since Celanese owns that IP space. That may or may not be a good idea, depending on your view of network management. We did this in case our customer needed to announce new networks which would save us the time/work of placing more/new route objects in the registry. We have the appropriate LOA for this network which is validated through face-to-face meetings with their network engineers and representatives. DataBank is very sensitive to network abuse; we have an AUP in place with all of our customers and will always work hard to enforce it to prevent network abuse. I apologize that I didn't respond sooner, but I have gotten behind on my NANOG reading. Thank you, Jason Pope DataBank Holdings 214.720.2266 office

State of QoS peering in Nanog
by Francois Menard 04 Apr '11

04 Apr '11

Folks, The Canadian telecommunications regulator, the CRTC, has just launched a public notice with possible worldwide implications IMHO, Telecom Notice of Consultation CRTC 2011-206: http://www.crtc.gc.ca/eng/archive/2011/2011-206.htm I think this is the very first regulatory inquiry into IP to IP interconnection for PSTN local interconnection. One of the postulates that I intend to defend, is that in the PSTN today, in addition to interconnecting for the purpose of exchanging voice calls, it is possible to LOCALLY (at the Local Interconnection Region, roughly a US LATA) interconnect with guaranteed QoS for ISDN video conferencing. In other words, there is more to PSTN interconnection than the support of the G.711 CODEC. Other CODECs are supported, such as H.320. This brings me to a point. Why should we loose this important feature of the PSTN, support for multiple CODECs, as we carelessly bottom level IP-IP interconnection to G.711 only. Video conferencing on the Internet, particularly at high resolution, is not a reality today to say the least, foregoing of guessing what the future will hold. Why not consider HD audio ? Therefore: A) I want to capture all instances where this issue has been addressed worldwide. B) I also want to understand what is going on, insofar as enabling guaranteed QoS peering across BGP-4 interconnections in the Nanog community. C) I also want to understand whether there is inter-service-provider RSVP or other per-session QoS establishment protocols. I call upon the Nanog community to consider this proceeding as very important and contribute to this thread. And I will try to provide a forum for discussing this outside of Nanog when required. Regards, -=Francois=-

HIJACKED: 159.223.0.0/16 -- WTF? Does anybody care?
by Atticus 04 Apr '11

04 Apr '11

This OT, and for those of you with virgin ears, don't read more. This is specifically to Ronald: Maybe, if you didn't act like a flaming douchebag, and were polite to people, they would be more interested in helping you out. Learn to use some fucking manners. Every single message I've seen from you has been condescending. I agree, this entire situation and situations like it are fucked up. That doesn't give you the right to start demanding answers from people, and in general treating everyone else like we are your personal servants, and are responsible for making sure your every whim is carried out. That being said, I'm probably going to get banned for that, but I feel it needed to be said. Grobe
