TWTelecom DNS issues...
by Wil Schultz 03 Mar '11

03 Mar '11

ns1.twtelecom.net and ns2.twtelecom.net (along with some other DNS servers, ns1.orng.twtelecom.net and ns1.ptld.twtelecom.net) suddenly stopped serving DNS for domains it's not authoritative for this morning. Requests are being actively refused from within their network. Caused a small issue for us, just thought I'd pass along. -wil

Switch with 24x SFP PVLAN QinQ Layer 2
by Adam Armstrong 02 Mar '11

02 Mar '11

Hi All, I'm scouring the Internet for potential devices to use in a FTTB/FTTP scenario. Requirements are basically just 24/48 SFP ports, PVLAN and selective QinQ. Most devices that fit the requirements are Layer 3, which pushes the cost per port too high. Has anyone come across anything I've not found yet? Thanks, adam.

Ok, see, now I (like, I suspect, Frank Bulk) am confused again: when you say "which L2 channels the RTP packets were flowed onto", that sounds to me a *whole* lot like "which VLAN on the end-user drop carried the RTP packets from the terminal adapter in their cable box to our concentrator"... which is pretty much the point I was originally trying to make, if perhaps in slightly different terms. Am I still misunderstanding you? Cheers, -- jra

IPv6? Why, you are the first one to ask for it!
by George Bonser 02 Mar '11

02 Mar '11

Fairly major global network provider likes to call themselves a "Tier 1". Asking about native IPv6 in one of their colo facilities in the UK. They say their US facilities won't be v6 capable until Q4 2011. The UK rep acted like it was the first he'd ever heard of it and implied we were the very first to ask for it. Note to providers: That might have worked a couple of years ago but when we hear that today, we know it is false. Please be honest in your responses to that question. If you aren't going to deploy it for another year or two, just say so. The notion that we are the very first ones to ever ask for it from a global provider in a major country is just lame. George

Issues with 23.1.64.0/20?
by Ernie Rubi 02 Mar '11

02 Mar '11

Anyone else see anything / know of any odd behavior on the prefix yesterday afternoon/today? Here in Miami (NAP) we saw some issues through one of our upstreams and ended up disabling the BGP session, then re-enabling it with a filter to block said prefix. We've since removed the filter and things are stable but would be nice to know what broke 'out there.' Ernesto M.

Video explaining [RPKI] Resource Certification
by Alex Band 02 Mar '11

02 Mar '11

Under the NRO flag, we have just released a short video about Resource Certification, giving a high-level explanation of what it is and why it is important for your organisation: http://youtu.be/rH3CPosGNjY I hope to release another video going into more detail, outlining what it means practically for an operator. To get an idea of the practical side for now, here is a video we released earlier on how to set up and use the hosted Resource Certification service the RIPE NCC provides: http://youtu.be/Q0C0kEYa1d8 Kind regards, Alex Band Product Manager, RIPE NCC

Request for assistance with BGP feeds
by Geoff Huston 02 Mar '11

02 Mar '11

Hi I am conducting some research relating to BGP behaviour and I need some eBGP multihop feeds - IPv4 and/or IPv6 eBGP, and full eBGP route table feeds please. These are incoming feeds only (I will be announcing _nothing_ back in these sessions - I'll filtering outbound and you should defensively filter inbound of course). I am looking at the real time behaviour of BGP updates in a relatively dense multi-peer environment, which is why I am looking for a number of full route feeds. Please drop me a note if you can assist me with this activity. Thanks in advance, Geoff -- Geoff Huston APNIC

Is anyone on the list that knows about the Coffer MAC address vendor database (http://www.coffer.com/mac_find/)? I have used this resource for years and I am now getting a permission error (403 Forbidden) when I try to go to any page on that site. Otherwise, anyone have recommendations for another resource for this information? Thanks, -Scott
