nanog53 network status
by Anton Kapela 10 Oct '11

10 Oct '11

Attendees, At present, we're aware of several issues affecting access to the NANOG attendee network -- in short, they include: -Apparent 'lumping' of iDevices, picking 11b/g channels of "1" and "6" (while channel 11 AP's sid idly by); adjusting additional AP's power and channel configuration to perturb this sub-optimal client selection logic. -AP's were permitting all frame bitrates (1 through 54 mbit encodings); these have been adjusted to include 5.5 mbits (cck, b) and 12 mbits (ofdm, g) encodings or greater (this reduces transmission duty cycles, frees up airtime, reduces contention, and hopefully performs better). -DHCP timer was set at 600 seconds; I'm informed that the lease time was increased to 3600 seconds at ~10:30AM PST today. Please relay any outstanding issues my way--I'll route to Verilan, which is handling the network and wireless support for the meeting. Best, -Tk

There was a reason the IETF kept going back to Minneapolis for meetings and it wasn't just the wild rice porridge at Hell's Kitchen. The Hilton there was extremely geek friendly and allowed us to take over both show floor and room networks. Great venue for network... - Lucy > /John > >

Re: Were A record domain names ever limited to 23 characters?

Found a decent starting reference. It was a Network solutions limit... I *knew* it! LOL http://www.123-domain-register.com/longdomainnames.htm The domain in question was inspectorgadgetthemovie.com 27 characters long including the .tld. I was off by one, the limit was 22 characters for the A record name and 4 characters for .com, .net, .org, .gov and .edu. >From the 123-domain-register web page: > The word is out... and the experts have been taking advantage of a change > in Domain Name regulations that allows up to 67 characters in domain names. > > How this will impact you: > > - > > Long domain names filled with keywords can get you ranked higher on the > search engines.

Announcement of University of Washington routing study
by Ethan Katz-Bassett 10 Oct '11

10 Oct '11

Hi NANOG, >From August 24 to October 4, the University of Washington and Georgia Tech will conduct an Internet routing study using AS-PATH poisoning. The study will *only* affect the Georgia Tech experimental prefix 184.164.224.0/19(and its sub-prefixes). The prefix serves *no active users/services* so the study should not affect any production prefixes or users. We plan to insert AS numbers into our announcements to route around some networks. We will always start AS-PATHs with our own ASN 47065. We will limit ourselves to at most 10 announcement changes per hour (and generally will change the announcement for a given sub-prefix at most every 90 minutes). This experiment is almost identical to one that Georgia Tech conducted in June and July without problems or complaints (http://mailman.nanog.org/pipermail/nanog/2011-June/037527.html) so we do not anticipate any issues. Others have done similar studies in the past (e.g., Randy Bush et al.: http://www.psg.com/~olaf/measurements/as3130/visibility.pdf<http://www.google.com/url?sa=D&q=http://www.psg.com/~olaf/measurements/as31…>). If, for any reason, you want us not to include your ASN in announcements for our prefix, please opt-out at any time before August 24 at: http://www.surveymonkey.com/s/9P2TD7T . A few ASes opted out of the previous Georgia Tech study, and we will continue to honor those opt-outs. Please feel free to contact me directly with any questions. Cheers, Ethan Katz-Bassett http://www.cs.washington.edu/homes/ethan/ University of Washington

2011.10.10 NANOG53 day 1 morning session notes
by Matthew Petach 10 Oct '11

10 Oct '11

I tried to take my usual notes from the video stream, but the quality of the stream was really bad; it kept pausing for 10 seconds, then jumping ahead on the audio, so there's big gaps that just didn't exist. :( I'm hoping the post-lunch stream will be better behaved. Posting the notes anyway, in case there's people who couldn't even get the choppy stream. Morning session notes are at http://kestrel3.netflight.com/2011.10.10-nanog53-morning-session.txt Matt

Amazon diagnosis
by Kristen Eisenberg 10 Oct '11

10 Oct '11

Sure they can, but as a thought exercise fully 2n redundancy is difficult on a small scale for anything web facing. I've seen a very simple implementation for a website requiring 5 9's that consumed over $50k in equipment, and this wasn't even geographically diverse. I have to believe that scaling up the concept of "doing it right" results in exponential cost increases. To illustrate the problem, I would give you the first step in the thought exercise: first find two datacenters with diverse carriers, that aren't on the same regional power grid (As we've learned in the (iirc) 2003 power outage, New York and DC won't work, nor will Ohio, so you need redundant teams to cover a very remote site).

NeuStar locality .us domains.
by Alex Romanauskas 09 Oct '11

09 Oct '11

I know it's not very common these days but I am a big fan of the <locality>.<ST>.us domain structure as it was setup 25+ years ago. Having been in the ISP industry for more than half that time I have also dealt with 100's of these registrations although maybe only 25 in the last year. Guess I have been lucky since all of them were with previously delegated localities. So today I go to register a domain for a friend, in what I consider to be a large enough city to have at least been delegated in the past (Lowell, MA) but of course it is currently assigned to NeuStar. I send in the request anyways, figuring there will just be some additional paperwork. This is the response I receive. ..... The US Department of Commerce has specifically stated that only certain 4th level domains can be registered until further notice. The DoC has only allowed us to register fourth level domain names beginning with "borough", "ci." for city, "co." for county, "twp." or "town" for township, or "vil." for village. ..... I have had a couple back and forths with there support department. Waiting for a response coming during the work week. Does anyone know the actual status of the locality .us structure? Are they trying to push people to the .us pay domains? Isn't NeuStar up for renewal on their last 1 year extension? -- Alex Romanauskas ZipLink / GNAPs
