Traceroute troubleshooting
by Joe Maimon 02 Nov '15

02 Nov '15

So we all know that its much more difficult to diagnose using that tool than just reading its output more often than not. Whats usually more important is correlation, over time and at any specific time. While tools such as mtr provide over time viewpoints, what can be run, user style, that will show packet loss/jitter over successive hops or in some sort of diagnosable pattern, as snapshots of data, when running the tool for some period of time where the long term averages/cumulative numbers will render such events mere statistical noise? Thanks! Joe

New ISPs getting of the ground without IPv4?
by nanog-isp＠mail.com 02 Nov '15

02 Nov '15

Surprisingly enough demand for Internet services did not end when we ran out of IPv4. I'd like to hear from the guys and gals starting new ISPs how they are facing this brave new world. Is it NATs all the way down? Is IPv6 the knight in shining armor? Are you getting enough IPs? If not, how are you coping? Buying/renting some, tunneling to somebody who has some, what? It's all good and well hearing about how you should dual stack and reading about how established players handle IPv6 and IPv4 exhaustion, but what do you do when dual stacking isn't an option and IPv6 only takes you so far? Now is your chance to shine and bring us some tales from the trenches :) Jared
