Google DNS intermittent ServFail for Disney subdomain

Hi Nanog, I am principal network engineer for sister-studio to Disney Studios. They have been struggling with DNS issues since Thursday 12th October. By all accounts it appears as though *some* of the Google DNS resolvers cannot reach the authoritative nameservers for "studio.disney.com". This

Updating Geolocation of /24 within corporate /16

Hi NANOG, You have given good advice on updating IP Geolocation data in the past, including visiting 'www.google.com' from a mobile device and selecting "use exact location [from GPS]". This worked out well for us a few years ago for a single IP which we were NATting out of in a new geographic

Re: IPv6-enabled multi-factor providers (not DUO)

Ahhh, a recent development — that's great news! Yes, it should be exceedingly simple for Duo to implement IPv6 :-) Thanks for the edification, all! -Dave On Thu, Feb 2, 2017 at 11:41 AM, Christopher Morrow <morrowc.li...@gmail.com > wrote: > > > On Thu, Feb 2, 2017 at 11:32 AM

IPv6-enabled multi-factor providers (not DUO)

Hi NANOG, (Apologies if this is slightly off-topic; there are a lot of IPv6-advocates here who might have some insights). At my day job, we use Duo Security for MFA. It works well, with the caveats that it's cloud-based and heavily dependent on Amazon AWS. We had an IPv4 outage last weekend and

Re: Need Comcast IPv6 routing assistance please

Hi John, I have been working with Courtney Smith and a fix has been implemented. Apparently a bunch of new Level(3) peering circuits were turned up on 5/15 and that's when the chronic packet loss problem started for our users. I have not been informed of the details as to what was causing such

Hello NANOG, Could someone from Comcast IPv6 routing team please contact me directly? I am both a business and residential comcast customer and my employer is a Level(3) HSIP customer at multiple sites. I'm seeing *consistent* 46.1% packet loss between Comcast Res/Bus services in Northern CA and

Re: 10G-capable customer router recommendations?

Thanks Aaron. Unless something has changed recently, I don't think the Brocade ICX series does NAT either. On Fri, Apr 15, 2016 at 2:52 PM, Aaron wrote: > Not a lot of 10G capable CPEs out there. For our 10G residential > customers we install Brocade ICXs. > >

10G-capable customer router recommendations?

Hello masters of the Internet, I was recently asked to set up networking at a VIP's home where he has Comcast "Gigabit Pro" service, which is delivered on a 10G-SR MM port on a Comcast-supplied Juniper ACX-2100 router. Which customer router would you suggest for such a setup? It needs to do IPv4

Really? Nobody here knows how one goes about updating IPv6 geolocation data? Our /48 is still being denied access to Google sites due to unknown geolocation. Help? Best, David On Tue, Dec 22, 2015 at 1:34 PM, David Sotnick <sotnickd-na...@ddv.com> wrote: > Hello, and Season's Greeting

How to update IPv6 geolocation data? Google sites blocked.

Hello, and Season's Greetings! We recently lit up a new IPv6-connected location and expanded our ARIN-allocated /48 network to a /44 network to accommodate the additional location (and future locations). However, since moving our small satellite office off our primary /48 and onto their own /48

Multiple vendors' IPv6 issues

Hi NANOG, The company I work for has no business case for being on the IPv6-Internet. However, I am an inquisitive person and I am always looking to learn new things, so about 3 years ago I started down the IPv6 path. This was early 2012. Fast forward to today. We have a /44 presence for our

Severe latency at both San Jose and Los Angeles Level3/ATT peering

Hi Nanog, I have a ticket open with Level 3, with whom I have 1gig pipes in Oakland, CA and Las Vegas, NV. One of our users noticed very slow file transfer/media delivery from the Bay Area to L.A., and on investigating it appears as though the peering point between Level3 and ATT in SF was
