The adventures of Team ARIN
by Jeroen Massar 27 May '09

27 May '09

Semi-Off-Topic here, I know, but it might help Network Operators to explain certain misguided people and thus lower noise and raise signal in various places. https://www.arin.net/knowledge/comic.html Short short synopsis: comic about how ARIN handles certain things and what ARIN does etc. Greets, Jeroen -- Currently published issues: Issue 1 - The Beginning of Team ARIN ----------------------------------------- Synopsis: In issue 1, learn how Team ARIN was founded with the assistance of Jon Postel. See how active participation by the entire Internet community is key to Team ARIN's success as it endeavors to facilitate the open and transparent, bottom-up policy development processes. Issue 2 - "FUD for Thought" ----------------------------------------- Synopsis: In issue 2, Team ARIN embarks on a mission to raise awareness about the issue of depletion of the available pool of IPv4 addresses and encounters a new enemy -- Agent FUD. Working for the "Bad Idea Force," FUD is busy trying to spread fear, uncertainty, and doubt about IPv4 address depletion. Using newly acquired technology, Team ARIN combines forces to help combat this new enemy of the open and transparent principles the Internet is based on, and in doing so creates something more than even they expected! Issue 3 - "FUD 2.0 - Return of the FUD Factor!" ----------------------------------------- Synposis: Issue 3 begins with Team ARIN flying back from a conference when they are alerted to a new problem and an old enemy. Agent FUD has returned and this time he's seeking to undermine the Internet community's migration to IPv6. Read the issue to find out how Team ARIN saves the day and how you can help! (s/synposis/synopsis/ by me, that typo is still on the original site, rest of content all by ARIN, nothing I can do about, thus don't complain to me ;)

Checking bogon status of new address space
by Oliver Hookins 27 May '09

27 May '09

Hi, my company has just been allocated some new IPv4 address space, and I want to do some sort of automated testing to find out any ASs out there that haven't removed the /8 it's on from their bogon list (the allocation to our local registry only occurred in November last year). Has anybody attempted to do this? It is worth bothering? Currently I'm considering pulling out all the endpoint ASs out of the BGP table, finding at least one subnet for each of them and attempting to ping or reach other common ports on a single IP for each AS from our currently working address space, and then the new address space and comparing results. -- Regards, Oliver Hookins Anchor Systems

Colo on the West Coast
by Pshem Kowalczyk 27 May '09

27 May '09

Hi, I'm looking for a colo provider somewhere on the west coast, preferably somewhere close to one of the peering exchanges. A virtual machine will do. I want to use it to run a small performance monitoring box (traceroutes, pings, etc). I also would like to get a full bgp feed into it so I can monitor bgp as well. Who do you think would be the best one to do it with? (answers can be off-list) kind regards Pshem

Glen, IPSECME WG <http://www.ietf.org/html.charters/ipsecme-charter.html> at IETF is actually working on the exact issue that you have described (unable to deep inspect ESP-NULL packets). You can look at draft-ietf-ipsecme-traffic-visibility-02<http://tools.ietf.org/html/draft-ietf-ipsecme-traffic-visibility-02>for more details.

I'm curious about the reasons for using high-amp 120 volt circuits to drive racks of equipment instead of low-amp 208 or 240 volt circuits. ~Seth

Hi, > I thought i'd give you a quick response (and welcome to NANOG) :). Thanks. I can't believe that I've already received three very interesting responses in just over an hour ! I've been quietly lurking on NANOG for a while, just plucked up the courage to post ..... and might now even find a bit more courage to attempt to contribute to some threads ! Glad to see the community spirit still exists ! Keep the replies coming if there are any still on their way ..... :) Tim P.S. Valdis Kletnieks ..... I've got the feeling that this .... > That 507 is critically important if it's true, might potentially explain a few intermittent unexplicable issues we've been seeing at some sites .... time for some research me thinks.... :)

PLNOG3 - 10-11.09.2009 - Call for Papers!
by Lukasz Bromirski 26 May '09

26 May '09

Hello, Polish Network Operators Group (PLNOG)[1] will meet for the third time ever on 10th and 11th of September 2009 in Cracow, Poland. We would like to invite You all to submit your presentation proposal. The plan for PLNOG 3rd is to have three tracks: * Architectures and technologies - sessions covering networking solutions, future of standards and the standarization process for current technologies; * Real-life deployments and best practices - sessions covering first-hand experience with deployment of specific solutions, products and solutions * Content provider architecture and scalability - dedicated for people interested in building backends for all kinds of networking sites like portals, community sites and etc. Additionally, we would like to invite You to suggest subjects for the open discussion sessions that will take place before the main event and after the keynotes. Last subjects revolved around IPv6 deployment and lawful intercept issues from the government and practical point of view. The submissions will be discussed by the PLNOG board[2], so the dead line for them is 25th of June, 2009. The full agenda with all sessions will be published no later than to 10th of July, 2009. CfP proposals should be sent to following e-mail: andrzej.targosz {%} proidea.org.pl with the prefix 'PLNOG3' in subject. We would also like to invite all vendors to participate in presentations - however, bear in mind please no vendor-oriented sessions will be permitted, which means no sales, no marketing, only pure technical stuff. The pointers to some specific design issues, products or solutions are allowed if they follow approved presentation flow and are relevant to subject covered. Last but not least - if You want to sponsor PLNOG we'd be more than happy to discuss this with You.
