Getting a "portable" /19 or /20
by mike harrison 09 Apr '01

09 Apr '01

With the demise of Winstar/good.net locally, and us having to renumber anyway, I am getting started on the idea of getting a 'portable' /19 from Arin. We are currently using a non-portable /20 and a couple of /24's. Any words of advice as we start this process? I'd like to do this right the first time and could use an experienced viewpoint.

This is actually an improvement, it used to take me that long to convince them we had a problem. I miss the days they were good.net and I could email actual people with a clue. Overall, they had been pretty decent to deal with and I'll miss them. --Mike--

Maybe you didn't realize you'd also contacted the administrators for AS7046: AS Nets then Nets now Net gain/loss AS7046 333 so low it's off the CIDR report! This may not be all your doing; I'd like to think the Internet community would have been working on it anyway, but social pressure does seem to help. Another 100,000 routes and we'll all be fine. Let me point out that the views of Messrs. Nussbacher and Huston are not incompatible. The ASNs appearing on Tony Bates's CIDR Report do seem to have made significant progress, but the Huston report at NANOG (reprised at ARIN) suggest that most growth is due to medium sized multihoming, which may not be reflected in the CIDR Report.

Now I guess some of these would have reduced their routing announcements in any event. Is this a scientific study? No. Does it show that perhaps the routing table growth can be flattened via contacting ASN admins? I believe the answer is yes. -Hank PS I have contacted AS8013 (PSA Canada) on March 6 (swip(a)PSI.CA, noc(a)psi.ca) No response and only a large growth over the past month.

BGP Economics ?
by Marshall Eubanks 09 Apr '01

Dear Geoff; I just noticed the remarkable flattening in the recent growth of the BGP table in your BGP graphs at : http://www.telstra.net/ops/bgp/index.html It didn't even seem this striking at Minneapolis. Is this cessation of growth real ? Is this a sign of the recent economic slow-down, or is there some more technical explanation (such as more aggressive aggregation at Telstra)?

I don't have any historical data to work with, but it would be interesting if someone could break down the total prefix count by length.

I'm located in Old Town Alexandria. We experienced no power problems of any sort during this time period. We also co-lo in Herndon and had no indications of any problems there either. -----Original Message----- From: Sean Donelan [mailto:sean@donelan.com] Sent: Thursday, April 05, 2001 9:41 PM To: nanog(a)merit.edu Subject: Northern Viriginia Power On Thu, 05 April 2001, John Starta wrote: > The service interruption was apparently a result of a major regional power > failure in Northern Virginia.

Other than a couple of stories about AOL IM being down, I couldn't find any news coverage of a major regional power outage in Northern Viriginia. The only story I found was an electrical fire at Dullas Town Center near the Gap store. VEPCO customer service didn't know of any power outages.
