Distributed DNS/etc checking
by Todd Snyder 04 Apr '12

04 Apr '12

Good day all, There have been a few instances where we've wanted to check our external DNS servers from various external networks, so we've utilized the existing looking glass tools provided by many of you. However, it's a very manual process, given that all LG's I've found say no automating/scripting. If we want to check from a couple dozen sites around the world, it's a lot of clicking and typing and collecting. If we wanted to create an tool that our NOC could use to verify our services, we would need something we could script. Ideally, we'd be able to run this constantly to do health checks on our services, but one step at a time. I've been googling, but so far I'm unable to find any larger scale projects/toolsets that we could use to simplify this process. Is anyone aware of something that would allow for me to submit a "job" to some sort of distributed service (I care about DNS, but others may care about traceroutes, pings, bgp information, etc), that will then run run the "job" and give me back an answer? Similarly, but perhaps differently, those of you who may run large anycast DNS services, how do you gather "external" stats about routing, response time, availability, and so on? It seems like this sort of thing would be a fairly common requirement (lets see how my network looks to those outside of it) but everything I can find is very manual at this point. This looks like a somewhat promising option, however I don't think I could get buy-in to run a node in our network, so it's not on the table for now: https://ring.nlnog.net/ This same functionality would likely be very helpful internal to large networks as well. I would love to know if I'm missing something obvious, or pieces of something obvious we could work with. Failing something already existing, I'd value any information people care to share about how they do this now, either on or off list. I can summarize any findings if the community is interested. Cheers, Todd.

Charter regional(nationwide?) flapping/multi outages
by jamie rishaw 03 Apr '12

03 Apr '12

[ This email takes place and context between 0817 GMT and 0910 GMT ] Charter is/was/has been/may still be hit by regional to national outages, starting ~ 0817 GMT Not only is my home ofc (100mb, quad doc3/rg6, hangs off chi) down (dying well within the network and not at cpe-adjacent gear), Charter NOC and Eng's cant even get to their ticketing and status/testing systems. They're dead in the water. (Voice service aside) ... : Three thoughts come to mind. 1) Tech says Charter (according to internal talk) has no v6 deploy plans until 2013. Someone stop me from pulling out my hair on this -- Does 3q '13 align with others' plans for v6 deployment ? 2) Eating your own dogfood is awesome, but where is a backup plan? My traces out during the ~30 mins on the horn had me routing thru Chi, Cle, and MO, dying at border/cores every time. Tethering my laptop to my android, I saw similarly-stopping routes inbound. (BGPlay disagrees, but thats another issue). Does it not behoove call centers and NOCs to have local access to replicated ticket and status dbs, failing over to alt carriers during severe outages (or any outage that takes down primary support)? 3) The first line tech suggested "it's DNS" (yet I run two of my own nameservers @ home, and roll neustar for global) -- Are we (senior types) just trying to get nocs off the phone with whatever answer, even if it involves lies that (we're naive to think) there /aren't/ those without clue that will challenge this, from premise to organization, sometimes *(cough)*. bringing these issues to a national stage? Thoughts, comments, insults, jokes, bring it. Anonymization assured should you want to go OTR and have me repost.

Step-by-step procedure for doing IPv6 subnetting
by Mukom Akong T. 03 Apr '12

03 Apr '12

Hello all I often get lots of people who want to know the procedure for doing IPv6 subnetting like we are used to in IPv4. Before using tools and utilities to make things easy, I always like to know the general principles. I've put up a post about a general and quick procedure on how to subnet in IPv6 which I believe gives anyone an good theoretical framework for how to do it. Please do check it out and let me feedback.

Reachability issue 193.56.43.0/24AS25186 from AS701
by Jérôme Nicolle 02 Apr '12

02 Apr '12

Hi, Just changed the upstream for this network and a few customers can't reach our services anymore. According to RIPE stats, reachability, is not optimal on the north american zone, but is perfect everywhere else (see https://stat.ripe.net/193.56.43.124) One of the complaining customer is on AS1660 and the route breaks within AS701. Could anyone confirm the reachability for this prefix from the US ? Anyone at Verizon to check and fix if necessary ? Thanks ! -- Jérôme Nicolle +33 6 19 31 27 14

French Regulator to ask all your information about your Peering
by Raphael MAUNIER 02 Apr '12

02 Apr '12

Hello All, This is now the end. The French regulator ( Arcep ) is now asking all the people with an ASN in France ( with a L33 license ) to get all their information on their peering. The Arcep claim it's for the "net neutrality" and still don't understand it works because it's self regulated. So, some of US network with a L33 License will also have to respond ( obligation because you have the L33-1) The documents can be downloaded here http://www.arcep.fr/index.php?id=8571&L=&tx_gsactualite_pi1[uid]=1508&tx_gs actualite_pi1[backID]=1&cHash=ed82d44a55 : ( french for now, english courtesy version will come soon ) The document is asking for informations like : BW, Prices, contract or not, level of use, date of the contract S You have to give them information twice a year We ( @Neo Telecoms ) and other folks in France will probably setup something with other carriers ( I already had some discussion with some of you ) to talk to them on a single voice. -- Raphaël Maunier NEO TELECOMS CTO / Directeur Ingénierie AS8218

RE: airFiber
by Nick Olsen 02 Apr '12

It will need perfect line of site. And won't deal with NLOS like most 2/5 ghz gear can. It's 24ghz. They claim 15Km. Maybe in the desert. In any climate with rain, Like our's here in Florida even 2 miles is going to be a stretch as 24ghz will rain fade easy. A great application for this would be like between two buildings requiring highspeed backhaul. (Were talking roof-top to roof-top of maybe a few thousand feet or more between them.

I am very interested in hearing about folks experience with this hardware once it ships. I almost posted it in the last-mile thread. Even compared to other hardware in the space the price-performance of it for the bitrate is amazing. I also recommend watching the video they posted: http://www.ubnt.com/themes/ubiquiti/air-fiber-video.html You are leaving out that it's an unlicensed band, so you can use this to have a decent backhaul to your house just by rigging it yourself on each end. - Jared -- Jared Mauch | pgp key available via finger from jared(a)puck.nether.net clue++; | http://puck.nether.net/~jared/ My statements are only mine.
