I have an InterNAP connection as well, and things are working fine if they pass through there.

Other than the two numbers/email addresses on their website does anyone know a contact for either one of these companies? The estimated hold time is less than 1 minute however I have been waiting 2 hours. I have tried their email addresses but only received the auto response (6 hours ago). .myke

Google it. And you're naive to you think its just VoIP anymore. The whole, nasty, underlying issue with 'network inequity' is that it is a bubble in its truest sense -- some infrastructure simply will not support tens of thousands, etc. unicast streams, AND also support traditional 'best effort' traffic. It's the old 'ten pounds of shite in a five pound bag' dilemma. Somethings gotta give ($) or something's gotta go ($) -- or be degraded somehow. Warnings on this were sounded ten (or more) years ago. :-) - ferg ps. Funny that -- the complexities of things these days vs. traditional recurring telco revenue streams. ;-) -- Alain Hebert <ahebert(a)pubnix.net> wrote: Eric Germann wrote: >Except when an ISP blocks Vonage completely, then they aren't neutral and it >is QoS (unless the QoS == 0 for VoIP) > > We (or its just me) might be curious about which ISP did that.

IP ranges, re- announcing 'PA space' via BGP, etc
by Alexander Koch 16 Apr '06

16 Apr '06

Folks, I see very often that customers in the US send morespecs all over the place, deaggregate whole /14s or such scary crap, ask us to accept random stuff out of 4/8 and 8/8 (L3 space) by example. I am practically asking what is (if any) the normal way for any of this. I am working by the principle that not everything I could do I should do, especially not right away. Is there any accepted procedure / policy for anyone to a) announce and b) accept (the transit supplier) and have that sanctioned formally? Maybe nobody cares, then tell me. ;-) Coming from Europe where pretty much everyone is RIPE LIR and has its own /21 at the least I might not see the problem that allegedly some (many) US ISPs do have. Enlighten me. (And, no, I do not fall for the urban legend that RIPE or ARIN are by default evil, clearly not. I do have real- life experience that whenever you can rightfully justify even large IP assignments you do get it.) Thanks, Alexander

RE: Open Letter to D-Link about their NTP vandalism
by Church, Chuck 14 Apr '06

14 Apr '06

"Service Area: Networks BGP-announced on the DIX" Since the intended (and announced) use of this server is just for DIX networks, blocking NTP from any other networks should be trivial. That IP address will still be hit by D-Link devices looking for a suitable server, but with no response, they'll move onto another device, and probably never try the DIX address again, at least until they're rebooted. That alone should kill off 95% of the unwanted traffic hitting the box, and probably 80% of the traffic even being sent to DIX in the first place. Chuck

Common Carrier Question
by Eric Germann 14 Apr '06

14 Apr '06

Folks, I'm working on a graduate policy paper regarding Internet filtering by blocking ASN's or IP prefixes. It is a variation of Net Neutrality, just by a different name. Is anyone in the IANAL field aware of any cases where : a. an ISP successfully defended a common carrier position b. an ISP unsuccessfully defended a common carrier position c. an ISP was treated as a common carrier, even if didn't want to be. d. an ISP was not treated as a common carrier, even if they wanted to. It seems to be way back in the 90's, Compuserve may have been involved in one variation of the above, but the cobwebs are too thick. Replies off list and I will summarize if there is interest. Eric
