Mark, > A EDNS referral from the root servers to the COM servers > already exceeded 512 bytes. The world hasn't fallen over. Actually, I was thinking to myself yesterday that the email world is going to be awfully fun when IPv6 sets in and we're all running mail servers with nice long AAAA records such as fc00:836b:4917::a180:4179. :)

Being as we are in Sydney, Australia and Gruber is in Phoenix, Arizona, USA, I don't think it'll be the most convenient arrangement. I just received a reply from APC saying even the warranty replacements don't get repaired. I guess there's a landfill somewhere full of faulty PDUs... -- Regards, Oliver Hookins Anchor Systems

Out of warranty APC PDU repair
by Oliver Hookins 27 May '09

27 May '09

Hi all, hopefully this isn't too off topic (since it's datacentre related). We have an APC AP7952 rack PDU which has stopped working. I believe the management module is faulty, and it is about 5 years old. APC don't service these outside of warranty at all so I'm trying to find a 3rd-party repairer. So far APC doesn't seem to understand this concept. Can anyone suggest a company that would work on these units in Sydney, Australia or nearby? -- Regards, Oliver Hookins Anchor Systems

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 have a pure curiosity question for the NANOG crowd here. If you run your facility/datacenter/cage/rack on 120 volts, why? I've been running my facility at 208 for years because I can get away with lower amperage circuits. 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
