You can use one AS and communities to seperate your traffic/policies. -jim ------Original Message------ From: Ryan Finnesey To: NANOG list Subject: regional ASN's Sent: Dec 1, 2010 1:13 PM I see various people are recommending networks setup regional ASN's.

Anyone know where I can buy cage nuts and rack screws locally near SAVVIS DC3 in Sterling, VA? They don't seem to have a local supply here, and somehow the racks we bought came with a 2:1 screw:nuts ratio. -cjp

New IPv4 blocks allocated to RIPE NCC
by Andrea Cima 01 Dec '10

01 Dec '10

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 [Apologies for duplicate mails] Dear Colleagues, The RIPE NCC received the IPv4 address ranges 5/8 and 37/8 from the IANA in November 2010. We will begin allocating from these ranges in the near future. The minimum allocation size for these two /8s has been set at /21. You may wish to adjust any filters you have in place accordingly. More information on the IP space administered by the RIPE NCC can be found on our web site at: <https://www.ripe.net/ripe/docs/ripe-ncc-managed-address-space.html> Additionally, please note that three "pilot" prefixes will be announced from each /8. The prefixes are: 5.0.0.0/16 5.1.0.0/21 5.1.24.0/24 37.0.0.0/16 37.1.0.0/21 37.1.24.0/24 They all originate in AS12654. More information on this "pilot" activity is available in the draft document "De-Bogonising New Address Blocks" which can be found at: <http://www.ripe.net/ripe/docs/ripe-351.html> Kind regards, Andrea Cima Registration Services Manager RIPE NCC -----BEGIN PGP SIGNATURE----- Version: GnuPG/MacGPG2 v2.0.11 (Darwin) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iEYEARECAAYFAkz2My0ACgkQXOgsmPkFrjOT7wCgnNa0eUFwK/ebtSeus3YgMoxZ GnUAnRAPMBMth/eSgX2F/opnY0fQI+Co =z5iw -----END PGP SIGNATURE-----

This depends on the eventual regulatory mechanism and the goals it intends to promote. Everyone in our industry has been aware that security mechanisms related to BGP are needed, but after major incidents making it into the news regularly for ten years, little progress has been made. A regulator putting the hammer down might be a driving force to solve some of our basically solvable problems that no one is willing to spend any time or money on. Additionally, it is easy to make the argument that reduced interconnection cost for end-user ISPs would never motivate any innovation. If any network with 1000 DSL users could connect to the closest PAIX (in every NFL city, of course) and gain access to all the big players for nothing but the cost of transport, it would not significantly reduce their cost to serve their customers. The DSLAMs, tech support monkeys, transport, idiotic implementation choices, etc. cost an order of magnitude more than transit. No regulator is going to believe that eliminating the cost of transit will encourage more broadband deployment, higher broadband speeds, or new inventions that tax the network more heavily. On the other hand, it is very easy for regulators to imagine that, if Youtube had to bear the whole cost of moving bits from them to the end-user, and broadband access was free for anyone with a house and mailbox, developing new applications would be much more expensive and happen less frequently. I think eyeball networks had better start demonstrating how they are innovating new things that benefit the public, and working hard to run their networks and businesses efficiently, before the regulation gauntlet is thrown down. Otherwise, they will be on the losing end. In either case, I don't think it automatically must be bad for all networks, and everyone except those eyeball networks should hope it turns out to be good for the public, increasing consumer choice and bringing new forms of information and entertainment into their homes. -- Jeff S Wheeler <jsw(a)inconcepts.biz> Sr Network Operator / Innovative Network Concepts

Static routes and reverse DNS with Cogeco
by Brian Raaen 30 Nov '10

30 Nov '10

I am assist a small cable system that is using cogeco as their backbone provider, and am running into some issues. I was wondering if anyone else has had sucess working with them. My issues are the following. 1. They absolutly refuse to delagate rDNS authority for a /24 2. I was told they "do not do static routes" when I asked if I could have my /24 circuit converted to a /30 and have the remaining subnets routed to my end of /30. Their suggested meathod is to put a router running proxy arp in front of my CMTS. I am trying to escalate my case, but it looks like I am being forced into some kind of proxy-arp setup. --- Brian Raaen Network Architech
