Resilient streaming protocols
by Aria Stewart 11 Jun '11

11 Jun '11

Anyone have any interest in a forward-error-corrected streaming protocol suitable for multicast, possibly both audio and video? Good for when there's some packet loss. ---- Aria Stewart

World of Warcraft may begin using IPv6 on Tuesday
by Kevin Day 09 Jun '11

09 Jun '11

For those that don't know, World of Warcraft is currently the largest online role playing game, with somewhere over 12 million subscribers. Version 4.1 of the game is expected to be released this Tuesday, which will be automatically pushed to all clients. The current Beta version of 4.1 has full IPv6 support. In the beta, it's automatically enabled if you have native IPv6 (non-6to4, non-Teredo). While Blizzard has been pretty silent about this, barring a last minute revert or delay of this patch, there are suddenly going to be a bunch more users that can potentially use IPv6. And these users are the type who are going to be especially sensitive to latency, jitter and packet loss, since this is a real-time game platform. For those of you with Help Desks who have to support users like this, the associated setting in the game's Options menu is apparently called "Enable IPv6 when available". It's apparently grayed out if you do not have IPv6 at all, unchecked by default if you are on 6to4 or Teredo, and checked by default if you are on native v6. The tooltip says: "Enables the use of IPv6, the technology behind the next-generation Internet. Requires IPv6 connectivity to the internet. Checking this box without IPv6 connectivity may prevent you from playing WoW." Anyone from Activision/Blizzard who would like to chime in with more details? :) -- Kevin

IPv6 Availability on XO
by Ryan Rawdon 07 Jun '11

07 Jun '11

I've heard some mixed reports of XO's IPv6 availability - some that they have full deployment/availability, but others like the answer back from our XO reseller that XO does not offer IPv6 on circuits under 45mbit/s. What is the experience of NANOG on this matter, particularly with XO connectivity under 45mbit/s?

blocking annoying 'bounce mail' "feature" from customers use.
by Eric J Esslinger 06 Jun '11

06 Jun '11

Mac Mail (and others) have a "feature" that allows my customers to generate a fake NDR message and send it back through my server. I get about a customer every few months that discovers this 'solution' to spam emails, and when it happens they cause delivery problems for my customer mail server by generating backscatter. Today I just ended up on a list that won't take me off for quite a while (or unless I pay). Does anyone know of a way for me to block the following, using postfix, either via refusing to accept the mail or by dropping it in /dev/null: Mail from <> or postmaster that originates within our customer IP blocks/is sent using authentication at the submission port and/or that does not have a valid local recipient. I can't find any ready made recipies online for this sort of thing in a short dig around for it, and while I think it's possible, I was wondering if anyone else was already dealing with this and could say 'oh yeah just put line blah in header_checks'. I would think it would be simple once you find it but you know how it is. (I've already dealt with the customer in question but I'm getting tired of this popping up every month or three.) __________________________ Eric Esslinger Information Services Manager - Fayetteville Public Utilities http://www.fpu-tn.com/ (931)433-1522 ext 165 This message may contain confidential and/or proprietary information and is intended for the person/entity to whom it was originally addressed.

Yahoo and IPv6
by Franck Martin 01 Jun '11

http://help.yahoo.com/l/us/yahoo/ipv6/general/ipv6-05.html "Will IPv6 become a permanent change on June 8, 2011? No. World IPv6 day is a 24-hour trial period in which we will publish our content on both the IPv4 and IPv6 servers. Yahoo! is participating in order to help prepare our services (as well as your hardware) to help ensure a smooth transition for when the IPv4 addresses run out. " Huh… I thought IPv4 addresses had run out already…. At IANA level and now for anyone in the AP region at least.

Verisign Internet Defence Network
by Jim Mercer 01 Jun '11

01 Jun '11

Heyo, So, I asked to look into the viability and usefullness of the "Verisign Internet Defence Network" service. I don't claim to be any kind of expert in DDoS mitigation, but some of the claims made by the product descriptions seem suspect to me. it claims to be "Carrier-agnostic and ISP-neutral", yet "When an event is detected, Verisign will work with the customer to redirect Internet traffic destined for the protected service to a Verisign Internet Defense Network site." anyone here have any comments on how this works, and how effective it will be vs. dealing directly with your upstream providers and getting them to assist in shutting down the attack? -- Jim Mercer jim(a)reptiles.org +1 416 410-5633 You are more likely to be arrested as a terrorist than you are to be blown up by one. -- Dianora

Deploying IPv6 globally
by eric clark 31 May '11

31 May '11

Many North American based organizations operate with their ARIN issued BGP AS distributed globally. When I discussed obtaining IPv6 space from ARIN a few years ago, they told me to submit an individual request for each of my sites (and they'd issue a /48 or larger based on the site). This is the process I've been following, until now, for my North American sites... My question is, has anyone started deploying ARIN IP space to their global offices? If so, how are you registering those sites with ARIN? Or did they tell you something else? Thanks -C

Cablevision's company line on IPv6 to the home
by Greg Ihnen 31 May '11

31 May '11

I just got off the phone with a level 1 tech support guy about an issue with my parents Cablevision/Optimum Online service and decided to ask the fellow if there's any official company news about IPv6 being in the works. His comments were that there is a test coming up (he was referring to World IPv6 Day), though he admitted that Cablevision is choosing not to participate in the "test" because they want to wait to see that IPv6 actually works without problems before they turn it on. He said it with a tone that seemed to express that the World IPv6 Day "test" is an irresponsible diversion. I politely and without any noticeable condescension (I believe) told him "that's what I expected" and bid him adieu. It's neat how they're going to skip that irresponsible testing phase and just turn it on one day and it's going to work perfectly. And I wonder how they'll know when IPv6 is done. Maybe is has one of those things that frozen turkeys have, that pops out when it's done. I've got my HE tunnels up and running on a Mikrotik hardware on the little networks I manage. I can't wait for IPv6 Day. So someone on the list please let Cablevision/Optonline know when you've finished IPv6. I'm sure they'd appreciate it. Greg
