Perhaps something similar would work here. Concur that this is the least-improbable model, absolutely. But keep in mind that subscriptions/services for in-home wiring were (and are) also a tiny percentage of the user base. ----------------------------------- Roland Dobbins <rdobbins(a)arbor.net>

routing issues between NTT/ATT/Level3?
by Nick Ellermann 26 Sep '16

26 Sep '16

Starting on 9/23 and really bad over the weekend we have had issues with end points out on AT&T's US network specifically in the Texas and Michigan areas. When our end points with AT&T drop, we end up losing monitored endpoints on Level3's network as well. Really bad periods of packetloss. Both of which for us are utilizing NTT as our upstream out of Ashburn. We have opened a ticket with NTT. Anyone else seeing similar issues? Since about noon today 9/26, it's gotten a little better but still periods of packet loss and dropped customer VPN tunnels. Probably not bothering the average web surfer but killing our customers voip and vpn traffic. It's really hard to diagnose and fix other vendors' networks!

by Matthew Crocker 26 Sep '16

Hello, Does anyone know the RTBH community for Lightower? I’ve tried 46887:666 but that doesn’t work. I have a /32 I need to blackhole, Lightower is the last ISP and it doesn’t appear they support RTBH ☹ Thanks -Matt -- Matthew Crocker President – Crocker Communications matthew(a)corp.crocker.com<mailto:matthew@corp.crocker.com>

IPv6 traffic percentages?
by nanog-isp＠mail.com 26 Sep '16

26 Sep '16

Hello all, Would those with IPv6 deployments kindly share some statistics on their percentage of IPv6 traffic? Bonus points for sharing top IPv6 sources. Anything else than the usual suspects, Google/YouTube, Netflix and Facebook? Some public information I've found so far: - Comcast around 25% IPv6 traffic ( http://www.lightreading.com/ethernet-ip/ip-protocols-software/facebook-ipv6… ) - Comcast has over 1 Tb/s (of mostly YouTube traffic) over IPv6 ( http://corporate.comcast.com/comcast-voices/comcast-reaches-key-milestone-i… ) - Swisscom 26% IPv6 traffic, 60% YouTube ( http://www.swinog.ch/meetings/swinog27/p/01_Martin_Gysi.pdf ) I'd be very much interested in hearing from smaller ISPs, especially those having a very limited number of IPv4 addresses and/or running out. Thanks, Jared

One year ago today, at 12:36pm EDT, Facebook On This Day reminds me, John Curran announced that the last IPv4 address block in ARIN's Free Pool had been assigned.
